At this point, the description will be made based on an example of the image displayed on the display unit 38a. As described later, ac actual content displayed in each region is properly changed according to each photography mode. The display region 60 includes a photography mode selection region 62, an illustration display region 70, a first photography condition setting region 80, and a second photography condition setting region 90.
The photography mode selection region 62 is a region where photography mode selection images 63, 64, 65, and 66 corresponding to plural X-ray photography modes are displayed. In this case, the photography mode selection region 62 is set to an upper region of the display region 60. The photography mode selection region may be set to another place of the display region, for example, a left region.
More specifically, the photography mode selection region 62 includes the panoramic photography mode selection image 63 corresponding to the panoramic photography mode, the cephalo photography mode selection image 64 corresponding to the cephalo photography mode, the CT photography mode selection image 65 corresponding to the CT photography mode, and the pseudo-intraoral radiography mode selection image 66 corresponding to the pseudo-intraoral radiography mode.
The panoramic photography mode is a photography mode that is performed to obtain one image of a whole mouth (or a part of the mouth) along a tooth row. For example, in the panoramic photography mode, the X-ray photography is performed with the turning arm 24 rotated within a predetermined range. An image indicating characters “Pan” is displayed as the panoramic photography mode selection image 63.
The cephalo photography mode is a photography mode that is performed to take a roentgenographic cephalogram. For example, in the cephalo photography mode, the X-ray photography of the head is performed from a given direction while the rotation of the turning arm 24 is stopped. An image indicating characters “Ceph” is displayed as the cephalo photography mode selection image 64.
The CT photography mode is a photography mode that is performed to obtain a tomographic image of the whole tooth row (or a part of the tooth row). For example, in the CT photography mode, the X-ray photography is performed while the turning arm 24 is rotated. An image indicating characters “CT” is displayed as the CT photography mode selection image 65.
The pseudo-intraoral radiography mode is a photography mode in which photography similar to the conventional intraoral radiography is performed by extraoral radiography in which a photograph is taken while the X-ray detector is disposed outside the mouth. Specifically, for example, tomosynthesis photography is performed while the whole photography region is irradiated with the X-ray during the photographing, and the image similar to the conventional intraoral radiography is taken based on the photography data of the tomosynthesis photography. For example, in the pseudo-intraoral radiography mode, the X-ray photography is performed while the turning arm 24 is rotated within a predetermined range. An image indicating characters “TTS” (meaning Teeth Tomosynthesis) is displayed as the pseudo-intraoral radiography mode selection image 66.
The panoramic photography mode selection image 63, the cephalo photography mode selection image 64, the CT photography mode selection image 65, and the pseudo-intraoral radiography mode selection image 66 are horizontally arrayed from left to right in this order in the photography mode selection region 62. The images displayed as the photography mode selection images 63, 64, 65, and 66 are not limited to the examples in
In the preferred embodiment, the four selection images of the panoramic photography mode selection image 63, the cephalo photography mode selection image 64, the CT photography mode selection image 65, and the pseudo-intraoral radiography mode selection image 66 are displayed in the photography mode selection region 62. There is no limitation to the selection images displayed in the photography mode selection region 62. Preferably at least two of the panoramic photography mode selection image corresponding to the panoramic photography, the cephalo photography mode selection image corresponding to the cephalo photography, the CT photography mode selection image corresponding to the CT photography, and the pseudo-intraoral radiography mode selection image corresponding to the pseudo-intraoral radiograph are displayed as the plural photography mode selection images in the photography mode selection region 62.
The touch detector 38b of a two-dimensional position detector that detects a touch position in the display region 60 is provided on the display region 60 of the display unit 38a. When a user touches one of the photography mode selection images 63, 64, 65, and 66, the touch detector 38b receives the selection operation for one of the photography mode selection images 63, 64, 65, and 66. When the selection operation is received, one photography mode selection image is displayed according to the selection operation while visually distinguished from other photography region selection images.
The illustration display region 70 is a region where illustration images 72 corresponding to the plural X-ray photography modes are displayed. The illustration display region 70 is disposed in a vertically middle portion of the display region 60 and in the widest range. In the illustration display region 70, an illustration image 72 suitable to display the photography mode selection images 63, 64, 65, and 66 is displayed according to the selection operation for the photography mode selection images 63, 64, 65, and 66 of the photography mode selection region 62.
The first photography condition setting region 80 is a region where the photography condition setting images corresponding to the plural X-ray photography modes are displayed. The first photography condition setting region 80 is provided in a right portion of the display region 60. At this point, a region-of-interest setting image 83A, a patient size selection image 83B, a projection setting image 83C, and a dental arch shape selection image 83D are displayed as the photography condition setting image corresponding to the panoramic photography mode in the first photography condition setting region 80. In the preferred embodiment, the region-of-interest setting image 83A is an image in which a region-of-interest illustration image is added beside characters “ROI”, the patient size selection image 83B is an image in which the illustration image indicating an upper half of the body and a character “M” indicating the size are added beside characters “Size”, the projection setting image 83C is an image in which the illustration images indicating the dental arch and a projection method is added beside characters “Proj”, and the dental arch shape selection image 83D is an image in which a dental arch shape is added beside characters “Jaw” or “Chin”. That is, the first photography condition setting region 80 mainly includes images used to set the photography conditions related to the subject in photography conditions. As described later, even in the same photography mode, existence and content of the display of one of the photography condition setting images 83A, 83B, 83C, and 83D can be changed according to the setting operation for the other of the photography condition setting images 83A, 83B, 83C, and 83D.
The second photography condition setting region 90 is a region where the photography condition setting images corresponding to the plural X-ray photography modes are displayed. The second photography condition setting region 90 is provided in a lower portion of the display region 60. At this point, in the second photography condition setting region 90, an irradiation setting image 93A, a tube voltage setting image 93B, a tube current setting image 93C, and a photographing speed setting image 93D are displayed as the photography condition setting image corresponding to the panoramic photography mode. The irradiation setting image 93A is an image in which a character “M” indicating manual setting is added below characters “Exp”, the tube voltage setting image 93B is an image in which a numerical character (in this case, “70”) indicating a tube voltage setting value is added below characters “kV” indicating a unit of tube voltage, the tube current setting image 93C is an image in which a numerical character (in this case, “8”) indicating a tube current setting value is added below characters “mA” indicating a unit of tube current, and the photographing speed setting image 93D is an image in which a setting state of speed (in this case, characters “HS” indicating High Speed) is added below characters “Spd” indicating the speed. That is, the second photography condition setting region 90 mainly includes images used to set photography device operating conditions such as an irradiation condition and an arm speed in the photography conditions. As described later, even in the same photography mode, the existence of the display of one of the photography condition setting images 93A, 93B, 93C, and 93D can be changed according to the setting operation for the other of the photography condition setting images 93A, 93B, 93C, and 93D.
<Entire Display Processing>
Entire display processing performed with the display unit 38a under the control of the main body controller 30 will be described with reference to
After positioning the subject M1 with respect to the photographing main body 20, the user sets the photography mode and the photography condition using the touch panel device 38 including the display unit 38a and the touch detector 38b.
In step S1, the main body controller 30 displays a setting screen. The example in
In step S2, the main body controller 30 receives the selection operation for one of the plural photography modes (step (b)). The user touches one of the photography mode selection images 63, 64, 65, and 66 displayed in the photography mode selection region 62, which allows the user to select the photography mode in which the photograph is taken. The touch detector 38b receives the user selection. In the case that any photography mode selection images 63, 64, 65, and 66 are not selected, the already-selected photography mode may continuously be selected.
The flow goes to step S3 when the panoramic photography mode is selected in step S2, the flow goes to step S6 when the cephalo photography mode is selected in step S2, the flow goes to step S9 when the CT photography mode is selected in step S2, and the flow goes to step S12 when the pseudo-intraoral radiography mode is selected in step S2.
In step S3, the image corresponding to the panoramic photography mode is displayed on the display unit 38a. For example, the image in
At this point, in the photography mode selection region 62 of the display unit 38a, one of the plural photography mode selection images 63, 64, 65, and 66 is displayed in the visually distinguishable manner according to the selection operation. In the example of
The illustration image is displayed in the illustration display region 70 of the display unit 38a according to the selection operation. For the example in
A first photography condition setting image is displayed in the first photography condition setting region 80 of the display unit 38a according to the selection operation. For the example in
A second photography condition setting image is displayed in the second photography condition setting region 90 of the display unit 38a according to the selection operation. For the example in
In step S4, first photography condition setting is received using the region-of-interest setting image 83A, patient size selection image 83B, projection setting image 83C, and dental arch shape selection image 83D in the first photography condition setting region 80 displayed on the display unit 38a.
In step S5, second photography condition setting is received using the irradiation setting image 93A, tube voltage setting image 93B, tube current setting image 93C, and photographing speed setting image 93D in the second photography condition setting region 90 displayed on the display unit 38a.
Then, the flow goes to step S15.
The flow goes to step S6 when the cephalo photography mode is selected in step S2.
In step S6, the image corresponding to the cephalo photography mode is displayed on the display unit 38a.
In steps S7 and S8, the first photography condition setting and the second photography condition setting are received similarly to steps S4 and S5. Then the flow goes to step S15.
The flow goes to step S9 when the CT photography mode is selected in step S2.
In step S9, the image corresponding to the CT photography mode is displayed on the display unit 38a.
Then, in steps S10 and S11, the first photography condition setting and the second photography condition setting are received similarly to steps S4 and S5. Then, the flow goes to step S15.
The flow goes to step S12 when the pseudo-intraoral radiography mode is selected in step S2.
In step S12, the image corresponding to the pseudo-intraoral radiography mode is displayed on the display unit 38a.
In steps S13 and S14, the first photography condition setting and the second photography condition setting are received similarly to steps S4 and S5. Then the flow goes to step S15.
Image examples corresponding to the cephalo photography mode, the CT photography mode, and the pseudo-intraoral radiography mode in the illustration display region 70, image examples in the first photography condition setting region 80, and image examples in the second photography condition setting region 90 will be described later while the display screens are illustrated.
In step S15, the main body controller 30 determines whether a photography start instruction is issued. For example, the photography start instruction is issued when the user touches a key 61 (in this case, a region “READY” displayed in a bottom right) displayed in the display region 60 of the display unit 38a. When the photography start instruction is not issued in step S15, the flow returns to step S2, and the pieces of processing from step S2 are repeated. When the photography start instruction is issued in step S15, the flow goes to step S16. In step S16, according to the set photography mode and photography condition, the drive part 27, the X-ray generator 22, and the X-ray detector 23 are controlled to perform the photography. Therefore, the processing related to the photography mode setting and the photography condition setting is ended.
As described above, when the selection operation is received in step S2, the processing of displaying one of the plural photography mode selection images 63, 64, 65, and 66 in the visually distinguishable manner in the photography mode selection region 62 is performed in steps S3, S6, S9, and S12 (step (c)). When the selection operation is received in step S2, the processing of displaying the illustration image 72 in the illustration display region 70 is performed according to the selection operation (step (d)). When the selection operation is received in step S2, the processing of displaying the photography condition setting image (such as the region-of-interest setting image 83A, the patient size selection image 83B, the projection setting image 83C, and the dental arch shape image example 83D) in the first photography condition setting region 80 is performed according to the selection operation in steps S3, S6, S9, and S12 (step (e)).
<Display Processing in Panoramic Photography Mode>
A display processing example in the case that the panoramic photography mode is selected will be described more specifically.
As described above, the display image example of the display unit 38a in the case that the panoramic photography mode is selected includes the photography mode selection region 62, the illustration display region 70, the first photography condition setting region 80, and the second photography condition setting region 90.
In the photography mode selection region 62, the case that the panoramic photography mode selection image 63 is displayed in color (including different shade of color) different from the mode selection images 64, 65, and 66 while being distinguishable from the mode selection images 64, 65, and 66.
The illustration display region 70 is the region where the illustration images 72 corresponding to the plural X-ray photography modes are displayed. For the example in
As illustrated in
As described above, the region-of-interest setting image 83A, the patient size selection image 83B, the projection setting image 83C, and the dental arch shape selection image 83D are displayed as the photography condition setting image corresponding to the panoramic photography mode in the first photography condition setting region 80.
As described above, the irradiation setting image 93A, the tube voltage setting image 93B, the tube current setting image 93C, and the photographing speed setting image 93D are displayed as the photography condition setting image corresponding to the panoramic photography mode in the second photography condition setting region 90.
<First Photography Condition Setting Processing>
In step S21, the setting of the region of interest (ROI) is received using the region-of-interest setting image 83A. That is, the region-of-interest setting image 83A is the image in which the region-of-interest illustration image is added beside the characters “ROI”. When the user touches the region-of-interest setting image 83A, plural region-of-interest setting images 83A1 to 83A4 are displayed as illustrated in
The setting of the region of interest (ROI) is received when the user touches one of the horizontally-displayed images 83A1 to 83A4. In the case that the reception of the setting of the region of interest is not changed, the flow goes to the next processing while the current region of interest is not changed.
In the case that the standard panorama setting image 83A1 is selected, the image in
In the case that the maxillary sinus panorama setting image 83A2 is selected, as illustrated in
In the case that the jaw or chin joint setting image 83A3 is selected, as illustrated in
In the case that the right-and-left-part panorama setting image 83A4 is selected, as illustrated in
As described above, an item that can be set as a first condition depends on the setting of the region of interest. The following processing will be described with the case that the standard panorama setting image 83A1 having the most setting items is selected as an example.
In step S22, the setting of the size is received using the patient size selection image 83B. That is, the patient size selection image 83B is the image in which the illustration image indicating the upper half of the body and the character indicating the size are added beside the characters “Size”. When the user touches the patient size selection image 83B, the plural patient size selection images 83B1 to 83B4 are displayed as illustrated in
When the user touches the patient size selection image 83B, the images 83B1 to 83B4 are horizontally displayed instead of the illustration image 72. At this point, the currently-set patient size is displayed while being distinguishable from other patient sizes. For the example in
The setting of the patient size is received when the user touches one of the horizontally-displayed images 83B1 to 83B4. In the case that the reception of the setting of the patient size is not changed, the flow goes to the next processing while the current patient size is not changed.
The processing of setting the patient size using the patient size selection image 83B is similarly performed even in the case that the photography of another region of interest is performed in the panoramic photography mode and the case that the photography is performed in another photography mode.
In step S23, the setting of the projection method is received using the projection setting image 83C. That is, the projection setting image 83C is the image in which the illustration image indicating the projection method and the characters indicating the projection method are added beside the characters “Proj”. When the user touches the projection setting image 83C, plural projection setting images 83C1 to 83C3 are displayed as illustrated in
When the user touches the projection setting image 83C, the images 83C1 to 83C3 are horizontally displayed instead of the illustration image 72. At this point, the currently-set projection method is displayed while being distinguishable from other projection methods. For the example in
The setting of the projection method is received when the user touches one of the horizontally-displayed images 83C1 to 83C3. In the case that the reception of the setting of the projection method is not changed, the flow goes to the next processing while the current projection method is not changed.
Even in the panoramic photography mode, the setting of the projection method varies depending on the region of interest. The projection setting image suitable to indicate the projection method is displayed according to the set region of interest. Sometimes the projection method is not set depending on the region of interest.
In step S24, the dental arch shape is received using the dental arch shape selection image 83D of the patient. That is, the dental arch shape selection image 83D is the image in which the illustration image indicating the dental arch is added beside the characters “Jaw” or “Chin”. When the user touches the dental arch shape selection image 83D, plural dental arch shape selection images 83D1 to 83D3 are displayed as illustrated in
When the user touches the dental arch shape selection image 83D, the images 83D1 to 83D3 are horizontally displayed instead of the illustration image 72. At this point, the currently-set projection method is displayed while being distinguishable from other projection method. For the example in
The setting of the dental arch shape is received when the user touches one of the horizontally-displayed images 83D1 to 83D3. In the case that the reception of the setting of the dental arch shape is not changed, the flow goes to the next processing while the current dental arch shape is not changed. In the case that the illustration image 72 indicating the plan view of the dental arch is displayed as the illustration image 72, the shape of the plan view of the dental arch displayed as the illustration image 72 may be changed according to the dental arch shape set in step S24. For example, in the case that the dental arch having the horizontally narrow width is selected, the image indicating the dental arch having the horizontally narrow width may be displayed as the illustration image 72.
Even in the panoramic photography mode, the setting screen of the dental arch shape is eliminated in the case that the photography is performed while another region of interest is set.
In step S25, the setting of the partial region to be photographed is received. The setting of the partial region is received using the entire jaw or chin panorama illustration image 72 displayed in the illustration display region 70. That is, as illustrated in
When the photography region selection operation is received, the photography region of the selected partial panorama is displayed in the visually distinguishable manner. For the example in
For the example in
As illustrated in
When the user touches one of the regions of the illustration image 72, the photography region selection operation is received, and the processing related to the reception of the setting of the first photography condition is ended. In the case that the reception of the setting of the photography region is not changed, the processing is ended while the current photography region is not changed.
<Second Photography Condition Setting Processing>
In step S31, the irradiation setting is performed using the irradiation setting image 93A. That is, the irradiation setting image 93A is the image in which the content of the irradiation setting is added below the characters “Exp”. When the user touches the irradiation setting image 93A, irradiation setting images 93A1, 93A2, and 93A3 are displayed as illustrated in
When the user touches the irradiation setting image 93A, the images 93A1, 93A2, and 93A3 are vertically displayed instead of the illustration image 72. At this point, the currently-set irradiation setting (in this case, “M” setting) is distinguishably displayed.
When the user touches one of the images 93A1, 93A2, and 93A3, the irradiation setting is received. In the case that the reception of the irradiation setting is not changed, the current irradiation setting is applied as is.
In step S32, the tube voltage is set using the tube voltage setting image 93B. That is, the tube voltage setting image 93B is the image in which a numerical value of the tube voltage is displayed below the unit of voltage “kV”. When the user touches the tube voltage setting image 93B, a tube voltage adjustment image 93B1 is displayed instead of the illustration image 72 as illustrated in
In step S33, the tube current is set using the tube current setting image 93C. That is, the tube current setting image 93C is the image in which a numerical value of the tube current is displayed below the unit of current “mA”. When the user touches the tube current setting image 93C, the tube current adjustment image 93C1 is displayed instead of the illustration image 72 as illustrated in
In step S34, the photographing speed setting is received using the photographing speed setting image 93D. That is, the photographing speed setting image 93D is the image in which a speed setting state is added below the characters “Spd”. When the user touches the photographing speed setting image 93D, plural photographing speed setting images 93D1 and 93D2 are displayed instead of the illustration image 72 as illustrated in
In the case that the automatic setting or the off setting is performed in step 31, the tube voltage setting image 93B and the tube current setting image 93C can be eliminated, or changed to another setting image.
It is possible that the embodiment example of the first and second photography condition setting processing can be regarded as an embodiment example of a processing to display a plurality of photography condition setting images corresponding to a plurality of photography conditions in or on a photography condition setting region.
The photography conditions may contain a photography condition comprising a plurality of subordinate photography conditions into which the photography condition is divided (The photography condition is a superordinate photography condition against the subordinate photography conditions).
For example, the first photography conditions may contain a photography condition such as a region-of-interest setting (83A in
The subordinate photography conditions may contain a photography condition (83A2 in
For example, the region of interest setting (83A in
The maxillary sinus panorama setting (83A2 in
A setting of the subordinate photography condition may be reflected on a display of a photography condition setting image of superordinate photography condition. For example, as shown in
As described in the explanation about
For example, the display of the illustration image 72 is replaced for the display of the photography condition setting images 93D1, 93D2 when the timing of the photography condition setting, and after the setting, the display of the photography condition setting images 93D1, 93D2 is replaced for the display of the illustration image 72.
It is possible to replace a display of an image for another one between timing of superordinate photography condition setting and timing of subordinate photography condition setting.
The above may be preferable for a display area of a display panel with a limited width.
<Display Processing in Cephalo Photography Mode>
The case that the cephalo photography mode selection image 64 is displayed in color (including different shade of color) different from the mode selection images 63, 65, and 66 while being distinguishable from the mode selection images 63, 65, and 66 is illustrated in the photography mode selection region 62.
For the example in
A region-of-interest setting image 84A, a patient size selection image 84B, a density correction setting image 84C, and a density correction start position setting image 84D are displayed as the photography condition setting image corresponding to the cephalo photography mode in the first photography condition setting region 80. According to the setting content of the region-of-interest setting image 84A, the existence of the display of one of the images 84B, 84C, and 84D can be changed, or the images 84B, 84C, and 84D can be changed to another image.
An irradiation setting image 94A and a tube voltage setting image 94B are displayed as the photography condition setting image corresponding to the cephalo photography mode in the second photography condition setting region 90. According to the setting content of the region-of-interest setting image 84A, another image (for example, the tube current setting image) can be added to the second photography condition setting region 90.
The setting of the region of interest, the selection of the patient size, the setting of existence of density correction, and the setting of the density correction start position are received using the first photography condition setting region 80. The reception setting processing in each of the region-of-interest setting image 84A and patient size selection image 84B is similar to that in the panoramic photography mode. In the processing of receiving each setting using the density correction setting image 84C, a soft tissue and a hard tissue can simultaneously be drawn by putting the display of the density correction setting image 84C into an on state, and the soft tissue is not drawn by putting the display into an off state. In the processing of receiving each setting using the density correction start position setting image 84D, when the display of the density correction start position setting image 84D is put into the on state, a numerical character indicating a density correction start position is displayed stepwise on a head illustration displayed in the illustration image display region 72, and the density correction start position and a density correction direction can be set back and forth in a stepwise manner from a surface of the soft tissue of the subject.
There is display processing in the case that the region-of-interest setting image 84A is selectively received as a recognizable processing example that is one of features in the cephalo photography mode. That is, the region-of-interest setting image 84A is the image in which the region-of-interest illustration image is added beside the characters “ROI”. The region-of-interest setting image 84A can also be recognized as the photography region selection image. When the user touches the region-of-interest setting image 84A, plural region-of-interest setting images 84A1 to 84A4 are displayed as illustrated in
The region-of-interest setting image 84A1 may be prepared for front cephalo photography. The region-of-interest setting image 84A2 may be prepared for side cephalo photography. The region-of-interest setting image 84A3 may be prepared for X-ray projection image photography in an angle between the front cephalo photography and the side cephalo photography. The region-of-interest setting image 84A4 may be prepared for X-ray projection image photography of a hand.
When the user touches the region-of-interest setting image 84A, the images 84A1 to 84A4 are horizontally displayed instead of the illustration image 72. At this point, the currently-set region of interest is distinguishably displayed. When the user touches one of the horizontally-displayed images 84A1 to 84A4, the setting of the region of interest (ROI) is received. In the case that the reception of the setting of the region of interest is not changed, the flow goes to the next processing while the current region of interest is not changed.
The reception of the selected setting of the region of interest also reflects the illustration image 72. That is, the illustration image indicating the head front external form is displayed similarly to the region-of-interest setting image 84A2 when the region-of-interest setting image 84A2 is selectively received, the illustration image indicating the head obliquely-rear external form is displayed similarly to the region-of-interest setting image 84A3 when the region-of-interest setting image 84A3 is selectively received, and, when the region-of-interest setting image 84A4 is selectively received, the illustration image indicating the hand external form is displayed similarly to the region-of-interest setting image 84A4 and an X-ray transmission image of the hand can be taken by putting a palm on the photography position.
Thus, the setting of the region of interest is received, and the setting reception processing is performed on other first photography conditions.
In the cephalo photography mode, the setting of the partial region to be photographed can be received using the illustration image 74. For example, the setting of the partial region is received using the illustration image 74 indicating the side face of the external head shape displayed in the illustration display region 70. That is, as illustrated in
When the photography region selection operation is received, the photography region of the selected partial panorama is displayed in the visually distinguishable manner. For the example in
The boundary line dividing the illustration image 74 is not necessarily displayed. Examples of the configuration in which the photography region is distinguishably displayed include a configuration in which the illustration image 74 is displayed while the photography region and the non-photography region are distinguished from each other using different colors, a configuration in which the photography region is surrounded by a frame, and a configuration in which the photography region is displayed with a pattern.
As illustrated in
When the user touches one of the regions of the illustration image 74, the photography region selection operation is received, and the processing related to the reception of the setting of the first photography condition is ended. In the case that the reception of the setting of the photography region is not changed, the processing is ended while the current photography region is not changed.
The description of the second photography condition setting processing will be omitted because the second photography condition setting processing is similar to the setting reception processing in the panoramic photography mode.
<Display Processing in CT Photography Mode>
The case that the CT photography mode selection image 65 is displayed in color (including different shade of color) different from the mode selection images 63, 64, and 66 while being distinguishable from the mode selection images 63, 64, and 66 is illustrated in the photography mode selection region 62.
For the example in
A region-of-interest setting image 85A, a patient size selection image 85B, a CT photography mode selection image 85C, a photography region setting image 85D, and a scan mode selection image 85E are displayed as the photography condition setting image corresponding to the CT photography mode in the first photography condition setting region 80. According to the setting content of the region-of-interest setting image 85A, the existence of the display of one of the images 85B, 85C, 85D, and 85E can be changed, or the images 85B, 85C, 85D, and 85E can be changed to another image.
An irradiation setting image 95A, a tube voltage setting image 95B, a tube current setting image 95C, and a resolution setting image 95D are displayed as the photography condition setting image corresponding to the CT photography mode in the second photography condition setting region 90.
The setting of the region of interest, the selection of the patient size, the selection of the CT photography mode, the setting of the photography region, the selection of a scan mode and the like are received using the first photography condition setting region 80. The reception setting processing using each of the irradiation setting image 95A, the tube voltage setting image 95B, the tube current setting image 95C, and the resolution setting image 95 is similar to that in the panoramic photography mode except for a specific content of each setting and the kind of each image.
There is display processing in the case that the region-of-interest setting image 85A is selectively received as a recognizable processing example that is one of features in the CT photography mode. That is, the region-of-interest setting image 85A is the image in which the region-of-interest illustration image is added beside the characters “ROI”. When the user touches the region-of-interest setting image 85A, plural region-of-interest setting images 85A1 to 85A3 are displayed as illustrated in
The reception of the selected setting of the region of interest also reflects the illustration image 72. That is, the illustration image indicating the jaw or chin joint in planar view is displayed similarly to the region-of-interest setting image 85A2 when the region-of-interest setting image 85A2 is selectively received, the illustration image indicating the side view of the whole dental arch including the jaw or chin joint is displayed similarly to the region-of-interest setting image 85A3 when the region-of-interest setting image 85A3 is selectively received, and the display of the FOV 85D in
In the case that the setting of the region-of-interest setting image 85A1 is received, the illustration image 75 indicating the whole dental arch in planar view is displayed, and the photography region for the dental arch is distinguishably displayed in the illustration image 75. For the example in
Thus, the setting of the region of interest is received, and the setting reception processing is performed on other first photography conditions.
In the CT photography mode, the setting of the partial region (size) can be received using the photography region setting image 85D. That is, the photography region setting image 85D is the image in which the image of the numerical vale (such as a diameter and a height) indicating the size of the photography region is added to the illustration (for example a columnar shape) three-dimensionally expressing the shape of the photography region, and the photography region setting image 85D can be recognized as the CT photography region size selection image. When the user touches the photography region setting image 85D, plural photography region setting images 85D1 to 85D8 are displayed instead of the illustration image 72 as illustrated in
The reception of the selected setting of the photography region also reflects the illustration image 75. That is, the photography region displayed in the illustration image 75 is changed according to the set diameter of the photography region. For example, when the photography region is set to the small diameter, the photography region (surrounded by a circle) displayed in the illustration image 75 becomes small as illustrated in
The reception of the selected setting of the photography region also reflects the photography region setting image 85D. That is, the image displayed in the photography region setting image 85D is changed according to the set diameter of the photography region. The displayed image is identical to the image selected from one of the photography region setting images 85D1 to 85D8. The photography region setting images 85D1 to 85D5 indicate different CT photography region sizes, and each of the photography region setting images 85D1 to 85D5 includes a columnar portion having a different size and a numerical value indicating the size (the diameter and the height). When the selection of the local CT photography mode (the selection of each of the images 85D1 to 85D2) is received, the local CT illustration image (one of the images 85D1 to 85D2) indicating the size of the local CT photography region is displayed as the photography region selection image 85D that is of the mode selection image. Therefore, the user can easily understand the size of the local CT photography region in performing the local CT photography.
In the CT photography mode, the setting of the partial region to be photographed can be received using the illustration image 74. For example, as illustrated in
The CT photography region may be set on an already-photographed panoramic image or a two-directional scout image (X-ray images from the front and side directions). In this case, the selection operation is performed using the CT photography mode selection image 85C, which allows the photography region to be set based on the panoramic image or two-directional scout image in addition to the setting of the photography region of the dental arch.
The processing of receiving the setting of the first photography condition is ended when the user ends the reception of the setting of the partial region to be photographed using the illustration image 74. In the case that the reception of the setting of the photography region is not changed, the processing is ended while the current photography region remains.
The description of the second photography condition setting processing will be omitted because the second photography condition setting processing is similar to the setting reception processing in the panoramic photography mode.
<Display Processing in Pseudo-Intraoral Radiography Mode>
The case that the pseudo-intraoral radiography mode selection image 66 is displayed in color (including different shade of color) different from the mode selection images 63, 64, and 65 while being distinguishable from the mode selection images 63, 64, and 65 is illustrated in the photography mode selection region 62.
For the example in
A photography condition setting image 86A, a patient size selection image 86B, and a dental arch shape selection image 86D are displayed as the photography condition setting image corresponding to the pseudo-intraoral radiography mode in the first photography condition setting region 80.
An irradiation setting image 96A, a tube voltage setting image 96B, a tube current setting image 96C, and a resolution setting image 96D are displayed as the photography condition setting image corresponding to the pseudo-intraoral radiography mode in the second photography condition setting region 90.
The setting of the photography condition, the selection of the patient size, the setting of the dental arch shape and the like are received using the first photography condition setting region 80. One of plural kinds of photography conditions can be selected in the setting of the photography condition. Each piece of setting reception processing using the photography condition is similar to that in the panoramic photography mode except for a specific content of each setting and the kind of each image.
Processing of receiving the setting of the partial region to be photographed using the entire jaw or chin panorama illustration image 76 can be cited as a recognizable processing example that is one of features in the pseudo-intraoral radiography mode. That is, previously-prepared plural selectable region images 76E overlap the entire jaw or chin panorama illustration image 76. Although a boundary of each region image 76E is added in
In the examples of
In
The selected region image 76E may be displayed while the images except for the region image 76E are eliminated. In addition to the touch on the display unit 38a by the user, the plural regions may be set by the selection using the mouse. Alternatively, a selection switch is separately provided in the operation panel, and one of the regions may be selected by the operation of the selection switch.
In the preferred embodiment, by way of example, the photographing target region is switched in a unit of block in which the plural teeth are collected by the 10-film method, the 12-film method, and the 14-film method. Alternatively, the photography region may be switched in a unit of tooth.
The pseudo-intraoral radiography region may be set on the already-photographed panoramic image. The region can similarly be set when each region overlaps the panoramic image.
When the user ends the reception of the setting of the partial region to be photographed using the illustration image 76, the processing of receiving the setting of the first photography condition is ended. In the case that the reception of the setting of the photography region is not changed, the flow goes to the next processing while the current photography region is not changed.
The description of the second photography condition setting processing will be omitted because the second photography condition setting processing is similar to the setting reception processing in the panoramic photography mode.
<Modifications Related to Region Designation>
In the preferred embodiment, the pseudo-intraoral radiograph region is set using the entire jaw or chin panorama illustration image 76. Alternatively, it is also conceivable that the region is set using the dental formula image as described below.
In the example of
As illustrated in
<Application of Region Designation of Local CT Photography>
The region designation processing applied in performing the pseudo-intraoral radiograph can also be used to designate the local photography region of the photographing target in performing the local CT photography.
Particularly, the region setting processing using the dental formula images 176 and 276 and the processing of visibly displaying the designated region, which are performed in the pseudo-intraoral radiograph as illustrated in
<Photographed Image Example>
Preferably the X-ray image obtained by photographing with the medical X-ray photography apparatus 10 is displayed while at least upper, lower, right, and left symbols overlap the X-ray image.
For example, in an example of
The image that is displayed while the upper, lower, right, and left symbols overlap the image may be the panoramic photography image, the cephalo photography image, and the CT image.
The dental formula number, the direction, or the block number may be displayed while overlapping the partial panorama image or the local CT photography image.
The photographed image example is not limited to the medical X-ray photography apparatus that performs the above-described pieces of processing, but can be applied to the various medical X-ray photography apparatuses
As described above, in the preferred embodiment, when the user operates one of the plural photography mode selection images 63, 64, 65, and 66, the operation receiver such as the touch detector 38b receives the selection operation, one of the plural photography mode selection images 63, 64, 65, and 66 is displayed in the visually distinguishable manner in the photography mode selection region 62 according to the selection operation, and the illustration image 72 is displayed in the illustration display region 70 according to the selection operation. Therefore, the user easily recognizes the selected photography mode before and after the selection operation, and the user easily sets the photography mode. After the selection operation, the user easily sets the photography region using the illustration image 72 displayed according to the selection operation in the display unit 38a.
When at least two of the panoramic photography, the cephalo photography, the CT photography, and the pseudo-intraoral radiograph are included as the photography mode to which the display processing is applied, the photography mode and the photography region are easily set during the selection of the panoramic photography, the cephalo photography, the CT photography, and the pseudo-intraoral radiograph.
When the selection operation for one of the plural photography mode selection images 63, 64, 65, and 66 is received, the photography condition setting image (such as the region-of-interest setting image 83A, the patient size selection image 83B, the projection setting image 83C, and the dental arch shape selection image 83D for the panoramic photography mode) is displayed in the first photography condition setting region 80 according to the selection operation. Therefore, the user can easily set the detailed photography condition corresponding to the photography mode.
Similarly, the user can easily set the detailed photography condition corresponding to the photography mode using the first photography condition setting region 80.
When the panoramic photography mode is selected, the illustration image 73 indicating the entire jaw or chin panorama or the illustration image 73a indicating the plan view of the dental arch is displayed in the illustration display region 70. Therefore, the user can easily set the photography region using the illustration image 73 indicating the entire jaw or chin panorama or the illustration image 73a indicating the plan view of the dental arch.
The user easily sets the photography region using the entire jaw or chin panorama illustration image 73. Because the selected photography region is displayed in the visually distinguishable manner in the entire jaw or chin panorama illustration image 73, the user easily sets the photography region while recognizing the selected photography region.
When the panoramic photography mode is selected, at least one of the patient size selection image 83B and the image indicating the jaw or chin shape of the photographing target is displayed as the image indicating the patient size in the first photography condition setting region 80, so that the user can easily set the detailed photography condition of the panoramic photography mode.
Because the dental arch shape selection image 83D is displayed as the photography condition setting image corresponding to the panoramic photography mode in the first photography condition setting region 80, the standard dental arch illustration image 83D1 indicating the standard dental arch and the protraction dental arch illustration image 83D2 indicating the protraction dental arch are displayed on the display unit 38a when the user selects the dental arch shape selection image 83D. When the user selects the standard dental arch illustration image 83D1 or the protraction dental arch illustration image 83D2 indicating the protraction dental arch, the illustration image is displayed in the illustration display region 70 according to the selection operation. Therefore, the user can easily change the illustration image displayed in the illustration display region 70.
When the user operates the patient size selection image 83B displayed in the first photography condition setting region 80 in each photography mode, the plural patient size selection images 83B1 to 83B4 are displayed. The user can easily set the patient size by selectively operating the plural patient size selection images 83B1 to 83B4.
The tube current setting image 93C and the tube voltage setting image 93B are displayed in the second photography condition setting region 90, the tube current or tube voltage adjustment image is displayed by the selection operation, so that the user can easily adjust the tube current and tube voltage while easily recognizing the tube current and tube voltage.
When the cephalo photography mode is selected, the illustration image 74 or 74(1) indicating the front or side face of the external head shape is displayed in the illustration display region 70. Therefore, the user easily sets the photography region using the illustration image 74 or 74(1) indicating the front or side face of the external head shape.
The illustration image 74 or 74(1) indicating the front or side face of the external head shape is divided into the plural regions while being able to be divided as the partial cephalo photography region, and the selection operation for at least one of the plural regions is received. Therefore, in the illustration image 74 or 74(1) indicating the front or side face of the external head shape, the selected photography region is displayed in the visually distinguishable manner, so that the user can easily designate the partial cephalo photography region.
When the CT photography mode is selected, the illustration image 75 indicating the plan view of the dental arch is displayed in the illustration display region 70. Therefore, the user easily sets the photography region using the illustration image 75 indicating the plan view of the dental arch.
The photography region setting image 85D that is of the CT photography region size selection image is displayed as the photography condition setting image corresponding to the CT photography mode in the first photography condition setting region 80. When the user selects the photography region setting image 85D, the photography region setting images 85D1 to 85D8 having different CT photography regions are displayed. The user can easily change the CT photography region size when touching one of the displayed images 85D1 to 85D8.
The user can easily change the region where the local CT photography is performed while checking the position of the circular shape indicating the local CT photography region of the illustration image 75 indicating the plan view of the dental arch.
When the pseudo-intraoral radiography mode is selected, the entire jaw or chin panorama illustration image 76 is displayed in the illustration display region. Therefore, the user easily sets the photography region using the entire jaw or chin panorama illustration image 76. Because the selected photography region is displayed in the visually distinguishable manner in the entire jaw or chin panorama illustration image 76, the user more easily sets the photography region while recognizing the selected photography region.
When the pseudo-intraoral radiography mode is selected, the dental formula image 176 or 276 is displayed in the illustration display region such that the photography region can be selected in each tooth number or each block including the plural tooth numbers using the dental formula image. At this point, the user easily sets the photography region in each tooth number or each block including the plural tooth numbers using the dental formula image. Because the selected photography region is displayed in the visually distinguishable manner in the dental formula image, the user more easily sets the photography region while recognizing the selected photography region.
The upper, lower, right, and left symbols overlap the actually-photographed X-ray image, which allows the user to easily recognize the direction of the X-ray image.
The configurations described in the preferred embodiment and modifications can properly be combined with each other unless the configurations are inconsistent with each other. Specifically, the combination machine having the panoramic photography function, the cephalo photography function, the CT photography function, and the pseudo-intraoral radiography function is mainly described in the preferred embodiment. However, the X-ray photography apparatus having at least one of the panoramic photography function, the cephalo photography function, the CT photography function, and the pseudo-intraoral radiography function is included in the scope of the present invention.
While the invention has been shown and described in detail, the foregoing description is in all aspects illustrative and not restrictive. It is therefore understood that numerous modifications and variations can be devised without departing from the scope of the invention.
