The image type may be displayed at the user interface.

Description

INTRODUCTION

Medical imaging is used for visualizing the inner structures and conditions of the human body. In the context of breast imaging, medical imaging contemplates detection of cancerous cells in breast tissue. A plurality of different imaging processes, image acquisition parameters, and image processing techniques are used to enhance images for better detection of abnormal tissue. A significant number of different images may be taken of a single breast or of a single patient. A technologist taking these images must work efficiently and accurately to take the images. Imaging errors may necessitate follow-up imaging, thereby exposing the patient to excess radiation.

SUMMARY

Examples of the present disclosure describe systems and methods relating to a method for determining an imaging type, the method including: displaying a visual representation of a breast and a visual representation of a medical imaging system capable of imaging the breast, wherein the visual representation of the medical imaging system includes a visual representation of a compression mechanism and a visual representation of an x-ray detector; receiving an indication to move the visual representation of the medical imaging system to a position and an orientation relative to the visual representation of the breast; displaying the visual representation of the medical imaging system in the position and the orientation relative to the visual representation of the breast; based on the position and the orientation of the visual representation of the medical imaging system relative to the visual representation of the breast, determining an image type of the medical imaging system; displaying the image type; and automatically adjusting at least one component of the medical imaging system based at least in part on the determined image type. In an example, the method further includes acquiring, while the breast is compressed by the imaging system, an x-ray image of the breast according to the determined image type. In another example, the method further includes receiving an indication to rotate the visual representation of the breast. In yet another example, the indication to rotate the visual representation of the breast is associated with rotation relative to a vertical axis along a length of the visual representation of the breast. In still another example, the orientation of visual representation of the medical imaging system is tilted relative to the visual representation of the breast.

In another example of the above aspect, the visual representation of the medical imaging system includes two parallel lines. In an example, the indication to move the visual representation of the medical imaging system includes an indication to rotate the visual representation of the medical imaging system in one of a clockwise or counter-clockwise direction. In another example, the indication to move the visual representation of the medical imaging system is a click and drag. In yet another example, the position and the orientation of the visual representation of the medical imaging system aligns with a predetermined position and a predetermined orientation.

In another aspect, the technology relates to a user interface for breast imaging, the user interface including: a visual representation of a breast; a visual representation of a medical imaging system capable of imaging the breast, wherein the visual representation of the medical imaging system includes: a visual representation of a compression paddle of the imaging system; and a visual representation of an x-ray detector of the imaging system; wherein the visual representation of the compression paddle and the visual representation of the x-ray detector are rotatable and positionable relative to the visual representation of the breast; and wherein an image type is displayed, based on a position and an orientation of the visual representation of the medical imaging system relative to the visual representation of the breast. In an example, the visual representation of the breast is three-dimensional. In another example, the visual representation of the breast is rotatable. In yet another example, the visual representation of the breast deforms based on the position and the orientation of the visual representation of a compression paddle and the visual representation of the platform relative to the visual representation of the breast. In yet another example, the visual representation of the breast includes a visual representation of two breasts. In still another example, the visual representation of the medical imaging system includes two parallel lines.

In another example of the above aspect, the two parallel lines are fixed relative to each other. In an example, the visual representation of the compression paddle and the visual representation of the x-ray detector are rotatable and positionable relative to a predetermined position and a predetermined orientation. In another example, the predetermined position and the predetermined orientation are associated with a specific image type. In yet another example, the image type is selected from a group consisting of: craniocaudal (CC); mediolateral oblique (MLO); mediolateral (ML); exaggerated craniocaudal lateral (XCCL); exaggerated craniocaudal medial (XCCM); cleavage view (CV); lateromedial (LM); tangential (TAN); caudocranial from below (FB); axillary tail (AT); lateromedial oblique (LMO); superoinferior oblique (SIO); and inferomedial superolateral oblique (ISO).

In another aspect, the technology relates to an apparatus for breast imaging, the apparatus including: an x-ray source capable of selectively moving relative to a breast; an x-ray detector; a compression system for compressing the breast, the compression system disposed between the x-ray source and the x-ray detector; a display; a processor; and memory storing instructions that, when executed by the processor, cause the apparatus to perform a set of operations including: displaying, at the display, a visual representation of the breast, a visual representation of the compression system, and a visual representation of the x-ray detector; receiving an indication to move the visual representation of the compression system and the visual representation of the x-ray detector relative to the visual representation of the breast; displaying, at the display, the visual representation of the compression system and the visual representation of the x-ray detector in a position and an orientation relative to the visual representation of the breast, based on the indication; based on the position and the orientation of the visual compression system and the visual representation of the x-ray detector relative to the visual representation of the breast, determining an image type; and displaying, at the display, the image type.

DETAILED DESCRIPTION

Various aspects of the disclosure are described more fully below, with reference to the accompanying drawings, which show specific example aspects. However, different aspects of the disclosure may be implemented in many different forms and should not be construed as limited to the aspects described herein; rather, these aspects are provided so that this disclosure will be thorough and complete and will fully convey the scope of the aspects to those skilled in the art. Aspects may be practiced as methods, systems, or devices. The following detailed description is, therefore, not to be interpreted in a limiting sense.

Breast cancer is one of the leading causes of cancer-related mortality of women. Abnormalities may be identified in the breast tissue by implementing one or more imaging techniques such as breast CT, breast tomosynthesis, and digital mammography. The imaging techniques are employed by emitting x-ray radiation from a source and detecting the radiation at a detector. A breast that is being imaged is placed between the source and the detector, and is typically compressed or immobilized therebetween. Placement and orientation of the source and detector relative to the breast may be adjusted. For example, different relative angles of radiation emitted through the breast may provide different view angles to view and/or assess an abnormality in the breast. The image types (otherwise referred to as image views) are based on the relative position and orientation of the source and detectors relative to the breast. Examples of image types include craniocaudal (CC), mediolateral oblique (MLO), mediolateral (ML), exaggerated craniocaudal lateral (XCCL), exaggerated craniocaudal medial (XCCM), cleavage view or “valley view” (CV), lateromedial (LM), tangential (TAN), caudocranial from below (FB), axillary tail (AT), lateromedial oblique (LMO), superoinferior oblique (SIO), inferomedial superolateral oblique (ISO), specimen, among others. Image types may be associated with one or more imaging modalities, such as conventional mammography, tomosynthesis, HD tomosynthesis, mammography/synthesis combination, HD combination, 2D contrast-enhanced, 2D contrast-enhanced combination, biopsy, quality control, etc.

Desired imaging type(s) are selected by a medical professional such as a technologist prior to imaging a breast with a medical imaging system. Traditionally, imaging type(s) are selected from a list of all available imaging types for a specific imaging modality. The list of image types may be provided as a list of images showing a breast relative to components of an imaging system (e.g., source and/or detector). This approach, however, requires the medical professional to scan through a list of options and navigate through different tabs on an interface. Additionally, by looking through a list of options, the medical professional needs to compare each list option with the configuration of the medical imaging system. Thus, the list format burdens the medical professional.

Accordingly, the present disclosure provides systems and methods for displaying, identifying, and selecting an image type for a medical imaging system. In an example, the present technology provides a user interface. The user interface includes a visual representation of a breast and a visual representation of a medical imaging system. The visual representation of the medical imaging system includes a visual representation of one or more of a detector, a source, and a compression paddle. The visual representation of the medical imaging system may be rotatable and positionable relative to the visual representation of the breast. Based on the relative position and orientation of the visual representation of the medical imaging system relative to the visual representation of the breast, an image type is determined. The image type may be displayed at the user interface. While the present disclosure is directed to breast imaging, the concepts and functions described herein are also applicable to imaging of other body parts (e.g., the abdomen, appendages such as arms and feet, etc.). Certain body parts, such as limbs, are more amenable to rotation thereof relative to a static imaging system. The systems and methods described herein that depict rotation of an imaging system relative to a static breast are equally applicable to rotation of a body part relative to a static imaging system; necessary or desirable modifications thereof would be apparent to a person of skill in the art upon reading this disclosure.

FIGS. 1A-1B show different views of an example imaging system 100. FIG. 1A depicts a schematic view of the example imaging system 100 and FIG. 1B depicts a perspective view of the example imaging system 100. The descriptions provided herein may be applied to either an upright (shown) or prone (not shown) imaging system 100. For simplicity, the following discussion includes examples for use with an upright breast tomosynthesis imaging system (such as the Dimensions Breast Tomosynthesis imaging system provided by Hologic, Inc.).

The imaging system 100 immobilizes a patient's breast 102 for x-ray imaging (either or both of mammography and tomosynthesis) via a breast compression immobilizer unit 104 that includes a static breast support platform 106 and a foam compressive element 108. Different paddles, each having different purposes, are known in the art. Certain examples paddles are also described herein for context. The breast support platform 106 and the foam compressive element 108 each have a compression surface 110 and 112, respectively, that move towards each other to compress, immobilize, stabilize, or otherwise hold and secure the breast 102 during imaging procedures. In known systems, the compression surface 110, 112 is exposed so as to directly contact the breast 102. Compression surface 110 may be a rigid plastic, a flexible plastic, a resilient foam, a mesh or screen, and so on. Compression surface 112 is a lower surface of the foam compressive element 108. The platform 106 also houses an image receptor 116 and, optionally, a tilting mechanism 118, and optionally an anti-scatter grid (not depicted, but disposed above the image receptor 116). The immobilizer unit 104 (otherwise referred to herein as the compression system 104) is in a path of an imaging beam 120 emanating from x-ray source 122, such that the imaging beam 120 impinges on the image receptor 116.

The immobilizer unit 104 is supported on a first support arm 124 via a compression arm 134, which is configured to be raised and lowered along the support arm 124. The x-ray source 122 is supported on a second support arm, also referred to as a tube head 126. For mammography, support arms 124, 126 can rotate as a unit about an axis 128 between different imaging orientations such as craniocaudal (CC) and mediolateral oblique (MLO), so that the imaging system 100 can take a mammogram projection image at each orientation. (The terms front, lower, and upper pertain to using a CC imaging orientation, with the patient facing the front of the imaging system, although it should be understood that other imaging orientations, including MLO, are used with the same equipment.) In operation, the image receptor 116 remains in place relative to the platform 106 while an image is taken. The immobilizer unit 104 releases the breast 102 for movement of arms 124, 126 to a different imaging orientation. For tomosynthesis, the support arm 124 stays in place, with the breast 102 immobilized and remaining in place, while at least the second support arm 126 rotates the x-ray source 122 relative to the immobilizer unit 104 and the compressed breast 102 about the axis 128. The imaging system 100 takes plural tomosynthesis projection images of the breast 102 at respective angles of the imaging beam 120 relative to the breast 102.

Concurrently and optionally, the image receptor 116 may be tilted relative to the breast support platform 106 and in sync with the rotation of the second support arm 126. The tilting can be through the same angle as the rotation of the x-ray source 122 but may also be through a different angle selected such that the imaging beam 120 remains substantially in the same position on the image receptor 116 for each of the plural images. The tilting can be about an axis 130, which can but need not be in the image plane of the image receptor 116. The tilting mechanism 118 that is coupled to the image receptor 116 can drive the image receptor 116 in a tilting motion. For tomosynthesis imaging and/or CT imaging, the breast support platform 106 can be horizontal or can be at an angle to the horizontal, e.g., at an orientation similar to that for conventional MLO imaging in mammography. The imaging system 100 can be solely a mammography system, a CT system, or solely a tomosynthesis system, or a “combo” system that can perform multiple forms of imaging. An example of such a combo system has been offered by the assignee hereof under the trade name Selenia Dimensions.

When the system is operated, the image receptor 116 produces imaging information in response to illumination by the imaging beam 120 and supplies it to an image processor 132 for processing and generating breast x-ray images. A system control and workstation unit 138 including software controls the operation of the system and interacts with the operator to receive commands and deliver information including processed-ray images.

The imaging system 100 includes a floor mount or base 140 for supporting the imaging system 100 on a floor. A gantry 142 extends upwards from the base 140 and rotatably supports both the tube head 208 and a support arm 210. The tube head 126 and support arm 124 are configured to rotate discretely from each other and may also be raised and lowered along a face 144 of the gantry 142 so as to accommodate patients of different heights. The x-ray source 122 is disposed within the tube head 208. Together, the tube head 126 and support arm 124 may be referred to as a C-arm 124.

A number of interfaces and display screens are disposed on the imaging system 100. Additionally or alternatively, a number of interfaces and display screens are disposed at the workstation unit 138, which may be located outside of a room of other components of the imaging system 100. These include a foot display screen 146, a gantry interface 148, a support arm interface 150, and a compression arm interface 152. In general, the various interfaces 148, 150, and 152 may include one or more tactile buttons, knobs, switches, as well as one or more display screens, including capacitive touch screens with graphical user interfaces (GUIs) so as to enable user interaction with and control of the imaging system 100. In general, the foot display screen 146 is primarily a display screen, though a capacitive touch screen might be utilized if required or desired.

FIG. 2 depicts a configuration of a user interface 200 for selecting an image type for a medical imaging system. The user interface 200 includes a set of image types 202, a set of image modalities 204, and imaging plan elements 206. The set of image types 202 includes a list of selectable image types on each tab for the set of image modalities 204. As shown, the “Conventional” modality tab is selected and shows a set of image types 202 organized by left and right breast imaging. Each tab for the set of image modalities 204 may include a different set of image types 202 associated with the selected tab. The imaging plan elements 206 include an “Add” element and a “Clear” element to add or remove one or more image types to a list. In an example, a medical professional using the user interface 200 may add one or more image types into a plan prior to imaging a breast. The image types may all be added to the plan before position the breast or after positioning the breast, or one or more image types may be added after positioning the breast for each image type.

FIG. 3 depicts an example user interface 300 for a medical imaging system. The user interface 300 includes a visual representation of a breast 302 and a visual representation of a medical imaging system 304. The visual representation of the breast 302 may be two-dimensional or three-dimensional. Additionally, the visual representation of the breast 302 may rotate along an axis disposed substantially parallel to the user interface 300 (or of the screen on which the user interface is displayed). For example, the visual representation of the breast 302 may swivel or pivot about an axis representing a position of a spine of a patient. The visual representation of the breast 302 may change in shape to deform based on the relative position and orientation of the visual representation of the medical imaging system 304. For example, the visual representation of the breast 302 may deform to mimic deformation of breast tissue under compression by the imaging system. The visual representation of the breast 302 may include visual representations of one or two breasts. An example that might be more intuitive for a technologist, however, includes a visual representation of both breasts 302 of the patient, as depicted in FIG. 3. This representation of both breasts 302 may remain fixed in a position that is consistent with the patient standing or sitting at an imaging system, e.g., the representation of both breasts 302 does not rotate. By not rotating, this provides the technologist with a consistent frame of reference.

The visual representation of the medical imaging system 304 includes a visual representation of a detector 308 and a visual representation of one or more of a source 306 or a compression paddle 306 of the imaging system. In FIG. 3, a paddle 306 is depicted. In this regard, the representation of both the detector 308 and the paddle 306 is again intuitive for a technologist, since the breast contacts the paddle and detector (or support platform under which the detector is located) during imaging. Regardless, as further described herein, a specific source 306 may additionally or alternatively be visually represented. As further described herein, the visual representation of the medical imaging system 304 may be rotatable and positionable relative to the visual representation of the breast 302. This may be the most intuitive configuration for a technologist, since during most breast imaging procedures, the patient remains upright while the detector, source, and compression system of the imaging system rotate. The visual representation of a detector 308 and the visual representation of the source or paddle 306 may be fixed relative to each other or, alternatively, may be independently moved (e.g, towards or away from each other) or rotated. To rotate the visual representation of the medical imaging system 304, a rotation element 310 may be selected. Although one rotation element 310 is shown, multiple rotation elements may be appreciated (e.g., one for the visual representation of a detector 308 and one for the visual representation of the source or paddle 306 and/or one for the visual representation of the breast 302). Interaction with the rotation element 310 at the user interface 300 (e.g., a click, a click and drag, etc.) may result in rotation of the associated visually represented element. Rotation may be stepwise or may be based on an amount of drag or time with which the rotation element 310 is interacted. Rotation of a visually represented element may be about a center of the element or a predefined point on an element. Rotation may also be about a point predefined by an approximate midway point between the detector 308 and the source or paddle 306. Rotation may be clockwise or counterclockwise along an axis of rotation.

The visual representation of the medical imaging system 304 shown in FIG. 3 includes two, two-dimensional parallel lines representing the detector 308 and the source and/or paddle 306. The distance between the parallel lines may be fixed or variable and may by representative of the relative position of the detector to the compression paddle. Additionally, the visual representation of the medical imaging system 304 may be two-dimensional or three-dimensional. The dimensions of the visual representation of the medical imaging system 304 may be the same as or different than the visual representation of the breast 302. In an example, the visual representation of the breast 302 is three-dimensional and the visual representation of the medical imaging system 304 is two-dimensional. In another example, both the visual representation of the breast 302 and the visual representation of the medical imaging system 304 are three-dimensional. In a further example, both the visual representation of the breast 302 and the visual representation of the medical imaging system 304 are two-dimensional.

Based on the relative position and orientation of the visual representation of the medical imaging system 304 relative to the visual representation of the breast 302, an image type is determined. The image type may be determined based on predetermined zones or regions containing the visual representation of the medical imaging system 304. Alternatively, the position and orientation of the visual representation of the medical imaging system 304 may be compared to predetermined positions/orientations, with each position/orientation associated with a specific imaging type. In an example, the actual position/orientation of the visual representation of the medical imaging system 304 relative to the visual representation of the breast 302 is compared with the predetermined positions/orientations to determine which predetermined position/orientation is closest. The visual representation of the medical imaging system 304 may be moved or rotated based on a click and drag action. In an example, the visual representation of the medical imaging system 304 may snap to the nearest predetermined position/orientation upon release of the click and drag action. The image type may be displayed at the user interface. Additionally, based on the determined image type, an image of a real breast is captured while the breast is compressed or immobilized by the imaging system.

Elements on the user interface 300 may include controls, graphics, charts, tool bars, input fields, icons, etc. Alternatively, other suitable means for providing input may be provided at the medical imaging system or at the workstation, for instance by a wheel, dial, knob, keyboard, mouse, bezel key, or other suitable interactive device. Thus, commands associated with the user interface 300 may be accepted through a display as touch input or through other input devices. Inputs may be received by the medical imaging system from a medical professional. A variety of gestures may be supported by the user interface 300, including a swipe, double-tap, drag, touch and hold, drag and drop, etc. A drag gesture may include an uninterrupted selection and movement. For example, a drag may include movement of a touch interaction across a touch surface without losing contact with the touch surface. The drag gesture may be similar to a swipe gesture over a longer time and/or at a slower speed. As further described herein, a drag gesture at the user interface 300 may visually change a portion of the user interface 300, such as by rotating or moving the visual representation of the breast 302 or the visual representation of the medical imaging system 304.

FIGS. 4A-4D depict different configurations of the example user interface of FIG. 3. For example, a first configuration 400A shows the visual representation of the medical imaging system 304 in a horizontal position/orientation relative to the visual representation of the breast 302 that is associated with an LCV (or Left Cleavage View) image type. In another example, a second configuration 400B shows the visual representation of the medical imaging system 304 in a horizontal position/orientation relative to the visual representation of the breast 302 that is associated with an LCC (or Left Craniocaudal) image type. In another example, a third configuration 400C shows the visual representation of the medical imaging system 304 in a tilted position/orientation relative to the visual representation of the breast 302 that is associated with an LMLO (or Left Mediolateral Oblique) image type. In a further example, a fourth configuration 400D shows the visual representation of the medical imaging system 304 in a vertical position/orientation relative to the visual representation of the breast 302 that is associated with an LML (or Left Mediolateral) image type. Although only four configurations are shown, other configurations associated with other image types are contemplated. For example, FIG. 2 depicts a number of breast image types, as known in the conventional mammography modality. A representation of any known or developed image type in any known or developed imaging modality may be utilized.

In an example application, a doctor or other specialist may, prior to an imaging procedure, select one or more image types to be later obtained by a technologist who is working with the patient and the imaging system. The specialist may select one or more image types depending on a previously-identified region of interest that requires further investigation, a prior diagnosis, or a to investigate a new suspect location. In most examples, the specialist may select the representation from a predefined list of representations of image types (such as the image types depicted in FIG. 2 or as otherwise known in the art). These particular representations may be saved to the patient's record, then accessed by a technologist during the imaging procedure. The technologist may select the image on a workstation or on an imaging system itself. The imaging system may then adjust automatically the position of any number of components to place those components in the general position required to take the selected image type. For example, for a right mediolateral oblique (RMLO) image type, the breast support platform and detector may tilt to an angle consistent with such an image type, as would the compression paddle. A tube head containing the x-ray source may move to a position out of the way of the technologist as she assists in placing and compressing the breast. Adjustments to the position of the detector and/or compression paddle may be possible to fine tune positioning as required or desired to accommodate patient comfort, anatomy, height, etc. Thereafter, the patient's breast may be compressed and the imaging procedure may be performed. Subsequent to imaging and release of the breast from the imaging system, the technologist may select the next required representation and the imaging system may automatically position its components as required in preparation therefor.

Each image type in a predefined list of image types includes a representation of the breasts, a representation of the detector (relative to the breast), and a representation of the paddle and/or source (relative to the breast and the detector), along with an indicator of image type (e.g., RCC, LXCCL, RCV, etc.). The technologies described herein, however, contemplate a user interface that may reflect non-standard relationships between a representation of the breast and the representation of the detector and paddle and/or source. In such a system, the representation of the detector and paddle and/or source may be movable relative to the representation of the breast. As such, based on the user control described above, the user may move the representation of the detector and the paddle and/or source along an x-axis (e.g., between the right breast representation and the left breast representation), along a y-axis (e.g., higher or lower along the breast representation), and about a z-axis (e.g., a rotation position reflected in the angle of the detector representation relative to the breast representation). Information may be provided on the interface (such as detector angle) for future reference by the technologist when preparing the imaging system. The ability to move the representations in the x-, y-, and z-axes allows the representation of the breast to reflect easy-to-understand conditions, so a technologist may readily ascertain the type of image required or desired.

Although the user interface technologies described herein are described primarily in the context of breast imaging, imaging of other types of body parts are also contemplated. Breast imaging is a particular type of imaging that allows for movement of the imaging system (e.g., detector and source) to accommodate an otherwise static body part (e.g., the breast is not easy or comfortable to manipulate). As such, adjustment of the representations of the detector and paddle and/or source are about three axes, generally. In imaging procedures for other body parts that are more easily manipulated relative to imaging system, position and rotation of the body part relative to the detector. For example, if the detector on an imaging system is fixed (e.g., such as with a table-type imaging system), the representation of the body part itself may be manipulated within the user interface, e.g., with regard to both position and degree of rotation, while a representation of the detector remains fixed. Imaging information such as specific pre-defined image type, angle of rotation of the body part, or other information, may be provided on the user interface.

In one example, based on a particular imaging procedure, a series of image types may be preloaded as a way to walk the specialist through an imaging procedure. For example, for a routine screening exam, it is typical to perform bilateral craniocaudal (CC) and mediolateral oblique (MLO) views. For patients undergoing a diagnostic exam, additional views may be indicated. The series of image types may be preloaded onto the workstation and displayed to the specialist. The series may be based on the types of screening exam, patient's electronic medical record, the practice at the imaging facility, the geographic region of the imaging facility, and prescribed indications by a radiologist.

FIG. 5 depicts an example method 500 for determining an image type for a medical imaging system. The method 500 may assist a user of an imaging system to determine an appropriate image type to image a breast, based on a configuration of the breast relative to the imaging system. The method 500 may be performed using systems described herein (e.g., imaging system 100 and user interface 300).

The method 500 begins at operation 502, where a visual representation of a breast and a visual representation of a medical imaging system are displayed. The display may be coupled to a medical imaging system or may be remote from a medical imaging system, such as at a remote workstation. The display shows a graphical user interface (GUI) that may have one or more features of the user interface 300 described with respect to FIG. 3. The visual representation of the medical imaging system may include visual representations of one or more components of the medical imaging system (e.g., the components shown in FIGS. 1A-1B of imaging system 100).

At operation 504, an indication to move the visual representation of the medical imaging system to a position and an orientation relative to the visual representation of the breast is received. The indication may be received at the GUI (e.g., via touch input) or may be received at a peripheral device connected to the display showing the GUI. In an example, movement and/or rotation of a visually represented element on the GUI may be a click and drag of the element. Visually represented elements being moved on the GUI may move relative to any received user input in real-time (e.g., an element moves according to a drag movement input).

At operation 506, the visual representation of the medical imaging system in the position and the orientation relative to the visual representation of the breast is displayed. The visual representation of the medical imaging system may snap to a closest position of a set of predetermined positions/orientations. For example, upon release of a click and drag input associated with the visual representation of the medical imaging system, the visual representation of the medical imaging system may be automatically re-positioned or re-oriented to align with a predetermined position/orientation. Each position/orientation of the set of predetermined positions may be associated with a unique image type.

At operation 508, an image type is determined based on the relative position and orientation of the visual representation. As further described herein, the image type may be based on which predetermined position/orientation is closest to the current position/orientation of the visual representation of the imaging system. Alternatively, the image type may be based on the current position/orientation of the visual representation of the medical imaging system being contained substantially within a predefined region or threshold. At operation 510, the image type is displayed. At operation 512, the imaging system may then adjust automatically the position of any number of components to place those components in the general position required to take the selected image type.

Operations 504-512 may repeat as required or desired. For example, if a visually represented element on the GUI is moved or reoriented relative to another visually represented element, the image type may be re-evaluated.
