1. Field of the Invention
The present invention relates to a medical support system and a method thereof. More specifically, the present invention relates to the system that enables a conference through bi-directional sharing of an image using a network, and the method thereof.
2. Description of the Related Art
With a development of communication technology, video conferences can be performed via the network such as the Internet at places that are distant from each other. For example, when the conference is performed in a medical field, the video conference is generally performed using only voice or both voice and the image (video). Also, a medical image is generally transmitted and received over the network and displayed. However, when details of an observation about the image are discussed during the conference, it is difficult to indicate a specific site to the other person without the image even when anatomical terms are used. In addition, when the medical image is transmitted and received, the transmission and reception are generally performed with compressed data, and thus the image may be deteriorated. Furthermore, in a remote place such as a foreign country, it may be necessary to interact with places where band frequency of network lines are different from each other, and the system is also needed to enable the conference even in this case. For example, Japanese Patent Laid-Open No. 2008-217294 discloses a technology that a doctor in a medical facility discusses with a doctor outside of the medical facility using the medical images in real time.
However, Japanese Patent Laid-Open No. 2008-217294 discloses that the real-time discussion is performed using the medical image, but there is no means for indicating a specific site in the image. Therefore, there is a risk that the recognition of the specific site is not properly shared with each other during the discussion. Also, Japanese Patent Laid-Open No. 2008-217294 does not disclose that operation information is transmitted only in one direction without sharing the operation information with each other. When the real-time discussion is performed using the medical image, unless otherwise properly indicated any specific site in the image, it is difficult to recognize the specific site through exchange of only words to thereby make a wrong diagnosis. Therefore, it is preferable to share the specific site recognized with each other and the other operation information with each other. Furthermore, when the conference is performed in remote places, the medical image for conference is compressed and transmitted or received if the band frequency of the network line is narrow, and thus a difference in quality of the shared image may be occurred due to deterioration of the image or the like.
The present invention provides a medical support system in which a medical image can be shared interacted with each other via a network at distant places in any line situation.
According to an embodiment of the present invention, a medical support system that enables one server bidirectionally connected to one terminal to bidirectionally communicate with another server bidirectionally connected to another terminal is provided, wherein each of the one server and the other server comprises: a conference processing unit configured to perform a conference between the one terminal and the other terminal; an image sharing processing unit configured to bidirectionally share an image between the one server and the other server; and a control unit configured to control the entire server over a network, wherein the control unit of the one server transmits only operation information sent from the one terminal to the control unit of the other server, and the control unit of the other server controls based on the received operation information.
According to the present invention, a medical support system in which a medical image can be shared interacted with each other via a network at distant places in any line situation can be provided.
Further features of the present invention will become apparent from the following description of exemplary embodiments (with reference to the attached drawings).
A telemedicine network system according to embodiments of the medical support system of the present invention will be described with reference to the drawings. Further, the embodiments shown below are specific preferred examples of the telemedicine network system of the present invention, and although various limitations that are preferable in terms of treatment may be applied, the technical range of the present invention is not limited by these unless specifically described otherwise. Also, components in the embodiment shown below may be appropriately replaced with existing components, and various variations including combinations with other existing components are possible. Therefore, content of the present invention described in the claims is not limited by description of the embodiments shown below.
Firstly, with reference to
With reference to
Next, a flow of the conference processing when the conference is started from the terminal 4 to the terminal 5 will be described with reference to
Next, in step S306, the conference processing unit 6 of the server 2 determines whether or not there is the video device such as the web camera to be used during the conference. When there is no video device (N), the processing proceeds to step S307, and the conference is performed without displaying the video. When there is the video device (Y), the processing proceeds to step S308. Then, in step S308, the connection request for the video device is transmitted to the conference processing unit 13 of the server 3. In step S309, the conference processing unit 13 of the server 3 that has received the connection request for the video device determines whether or not there is the video device. When there is no video device (N), the processing proceeds to step S310 and the conference is performed without displaying the video. When there is the video device (Y), the processing proceeds to step S311. Then, step S311, the response of the video device connection is transmitted to the conference processing unit 6 of the server 2.
Next, in step 312, the conference processing unit 6 of the server 2 determines whether or not there is an audio device. When there is no audio device (N), the processing proceeds to step S313 and the conference is performed without outputting voice. When there is the audio device (Y), the processing proceeds to step S314 and the connection request for the audio device is transmitted to the conference processing unit 13 of the server 3. In step S315, the conference processing unit 13 of the server 3 that has received the connection request for the audio device determines whether or not there is the audio device. When there is no audio device (N), the processing proceeds to step S316 and the conference is performed without outputting voice. When there is the audio device (Y), the processing proceeds to step S317. Then, in step S317, the response of the connection for the audio device is transmitted to the conference processing unit 6 of the server 2. After the connection processing for the video device and the audio device is completed, in step S318, the conference is started. Note that, while the conference processing from the terminal 4 to the terminal 5 has been described in the present embodiment, the conference may be started from the terminal 5 to the terminal 4. In this case, the flow is opposite to the flow of the conference processing described the above. In addition, the flow is not limited thereto and may be executed in a different order or the flows may be executed at the same time.
Next, the flow of the image sharing processing will be described with reference to
Next, in step S408, the image sharing processing unit 7 of the server 2 loads the medical image to be shared and temporarily stores the medical image in the image storage unit 8. When the medical image is temporarily stored in the image storage unit 8 of the server 2, in step S409, the control unit 10 of the server 2 creates a control thumbnail of the medical image to be shared. After or simultaneously with the processing in step S409, in step S410, the operation information for loading the image is transmitted to the image sharing processing unit 14 of the server 3. In step S411, the image sharing processing unit 14 of the server 3 receives the operation information transmitted from the image sharing processing unit 7 of the server 2, loads the medical image to be shared, and temporarily stores the medical image in the image storage unit 15 of the server 3. When the medical image is temporarily stored in the image storage unit 15, in step S412, the control unit 17 of the server 3 creates the control thumbnail. The sharing processing of the medical image required during the conference is completed with completion of the control thumbnail creation in the server 2 and the server 3 (step S413), and the respective servers hold the same medical image.
Next, a flow in which one of the servers does not have the medical image necessary to be shared in the conference will be described with reference to
Since the processing in steps S512 to S517 are the same as in steps S408 to S413 described above, detailed description thereof will be omitted. Note that, while the image sharing processing is performed from the server 2 to the server 3 in the present embodiment, the image sharing processing may be performed from the server 3 to the server 2. In this case, the flow is opposite to the flow of the image sharing processing as described the above. In addition, the flow is not limited thereto and may be executed in the different order or the flows may be executed at the same time. The shared medical image is displayed on the respective terminals 4 and 5 through the image display units 9 and 16. At this time, the shared medical image is not subjected to processing such as the compression processing or the like, and thus, when both the terminals 4 and 5 use the same display unit, fidelity of the medical image displayed on the terminal 4 is the same as the fidelity of the medical image displayed on the terminal 5.
In the present embodiment, the flow that the image sharing processing is performed after the conference processing has been described, but the present invention is not limited thereto and the processing may be independently executed at the same time or the conference processing may be executed after the image sharing processing. The conference processing is independently from the image sharing processing at the same time to thereby be able to shorten the time from start of the connection by the terminals between those who perform the conference to start of the actual conference.
Next, an operation of the medical image to be shared during the conference and a method for sharing information regarding the operation will be described with reference to
Next, the method for sharing the operation information when the plurality of images are displayed will be described with reference to
Next, the method for sharing the operation information when pointers of each other are caused to be displayed in the terminals 4 and 5, respectively will be described with reference to
Next, after or simultaneously displaying the pointer 1, the control unit 17 of the server 3 causes the image display unit 16 to display the pointer 2 operable on the terminal 5, the image display unit 16 transmits the display information to the terminal 5, and the pointer 2 operable on the terminal 5 is displayed on the screen of the terminal 5 in addition to the pointer 1. After or simultaneously causing the image display unit 16 to display the pointer 2, the control unit 17 of the server 3 transmits the operation information for displaying the pointer 2 to the control unit 10 of the server 2. The control unit 10 of the server 2 causes the image display unit 9 of the server 2 to display the pointer 2 based on the received operation information, the image display unit 9 transmits the operation information to the terminal 4, and the pointer 2 that is not operable on the terminal 4 is displayed on the screen of the terminal 4 in addition to the pointer 1.
In this case, colors of the pointer 1 and the pointer 2 displayed on the screen are changed so that the pointer 1 and the pointer 2 are distinguished from each other. For example, on the screen of the terminal 4, the pointer 1 operable on the terminal 4 is displayed in white, and the pointer 2 that is not operable on the terminal 4 is displayed in black. In contrast, on the screen of the terminal 5, the pointer 2 operable on the terminal 5 is displayed in white, and the pointer 1 that is not operable on the terminal 4 is displayed in black. After both pointers are displayed, the pointer 1 or the pointer 2 is moved based on the operation information sent from the terminal 4 or the terminal 5. For example, firstly, when the operation of laterally moving the pointer 1 operable on the terminal 4 is performed, the terminal 4 sends operation information to the control unit 10 of the server 2. The control unit 10 of the server 2 causes the image display unit 9 of the server 2 to display the pointer 1 moving based on the operation information, the image display unit 9 sends the display information to the terminal 4, and the pointer 1 is displayed so as to laterally move according to the operation on the terminal 4. After or simultaneously causing the image display unit 9 to display the pointer 1, the control unit 10 of the server 2 sends the operation information of the pointer 1 to the control unit 17 of the server 3. The control unit 17 of the server 3 causes the image display unit 16 of the server 3 to display the pointer 1 moving laterally based on the received operation information, the image display unit 16 sends the display information to the terminal 5, and the pointer 1 is displayed is displayed so as to laterally move on the terminal 5. In the present embodiment, while the colors of the pointers are white and black, the present invention is not limited thereto, and the colors of the pointers displayed on the screen of each terminal may be any colors as long as the operable pointer and the other pointer(s) (that is (are) not operable) can be distinguished from each other.
The operation of the medical image to be shared and the method of sharing the information for the operation during the conference have been described above. However, the present invention is not limited to this method, and the information for the operation performed by the terminal 4 or the terminal 5 may be shared over the network, and the operation may be performed based on the operation information and displayed on terminals of each other. Further, the operation of the medical image is not limited to the present embodiment, and may include, for example, at least one of various functions of a workstation according to the medical image, such as luminance/contrast adjustment display, zoom-in and zoom-out display, panning, partial zoom-in display, window frame fitting display, pixel equal-magnification display, full scale display, black and white highlight display, a color palette, an RGB component, an HSV component, an LUT, smoothing, sensitization, edge detection, a median filter, a threshold value, display condition preset, horizontal rotation display, vertical highlight display, horizontal highlight display, synchronized display of images in the same series, synchronized display of images in a plurality of series, angle measurement, measurement of angle relative to a reference line, length measurement, CT value measurement, oval ROI measurement, polygonal ROI measurement, arbitrary region ROI measurement, graphic drawing, text drawing, histogram display, marking, cardiothoracic ratio measurement, drawing overlay removal, image information display, overlay display/non-display, display layout setting, tile mode display, stack mode display, multiple series display, multiple series synchronized display, thumbnail image display, scout image display, reference line display, cine display, video display, series mode display, study mode display, hanging protocol function, display of mammography images in horizontal alignment, mammography image breast position automatic alignment, a mammography image horizontal interlocking magnifying glass, shaping measurement including any one of a cobb angle, FTA, and a sharp angle, implant simulation, an expansion correction function, or in the case of a 3D image a function of volume rendering, a 3D cursor, MPR, CPR, MIP, MinIP, Curved MPR, oblique, fusion, inter-volume calculation, a virtual endoscope, volume or distance measurement, fat measurement, extraction, composition, editing, or analysis. Also in this case, the operation information may be mutually shared with each other, and the same image or the like may be displayed between the terminals. Note that, after ending of the conference, the images temporarily stored in the image storage units 8 and 15 may be remained to be stored or may be erased.
Furthermore, in the present embodiment, the conference processing, the image sharing processing, and the operation of the shared image at the time of the conference between the terminal 4 and the terminal 5 via the servers 2 and 3 have been described. However, the present embodiment may be applied between the servers without using the terminal 4 and the terminal 5, for example, as long as each of the servers 2 and 3 includes the video device such as the web camera through which the conference is possible, the audio device such as the microphone, and the monitor or the display that displays the image to be shared.
Next, a flow in which the conference is performed among a plurality of (three or more) terminals will be described with reference to
According to the present embodiment, the image such as the medical image can be displayed and operated during the conference performed by transmitting the video and/or the voice with each other. Therefore, it is possible to provide a medical support system in which a medical image can be mutually shared over a network at distant places in any line situation and can be bidirectionally exchanged by mutual sharing of operation information.
