  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a schematic configuration of a medical information system to which an information processing apparatus according to an embodiment of the present invention is applied. In this medical information system, a medical image photographing device (modality) 1, an image display device (interpretation workstation) 2 comprising the above information processing device, an image server 3, and an image database 4 can communicate with each other via a network 10. It is configured to be connected to a different state. Each device in this system is controlled by a program installed from a recording medium such as a CD-ROM. The program may be installed after being downloaded from a server connected via a network such as the Internet.

  The modality 1 includes an apparatus that captures an examination target region of a subject, generates image data of an image representing the region, adds the accompanying information such as examination information and patient information to the image data, and outputs the image data. included. The incidental information is in a format conforming to a standardized standard such as the DICOM standard and a manufacturer's standard such as a modality thereof. Specific examples of the modality 1 include a CT apparatus, an MRI apparatus, a PET apparatus, and an ultrasonic imaging apparatus.

  The image data handled in this example is image data indicating a tomographic image of a subject acquired by a CT apparatus as an example, and more specifically, image data of an axial dislocation image with a predetermined slice interval and slice thickness. It is an aggregate. However, data handled by the information processing apparatus of the present invention is not limited to such image data.

  The image display apparatus 2 is an apparatus used by an image interpretation doctor or the like who is the user for interpretation of an image and creation of an interpretation report. As shown in FIG. 2, the image display device 2 has a processing device 21 including a storage device such as a CPU and a hard disk, a memory, various interfaces, etc., one or two high-definition displays 22 (only one device). And a computer system comprising an input means 25 such as a keyboard 23 and a mouse 24.

  As shown in FIG. 3, the mouse 24 has a position detecting ball or optical means (not shown) arranged at the bottom in addition to the left button 24a, the right button 24b and the wheel 24c as in the normal case. Have.

  Based on a program installed in the processing device 21, the image display device 2 that constitutes the image interpretation workstation receives an image browsing request to the image server 3, various image processes for the image received from the image server 3, and structures in the image And various analysis processes including automatic detection and highlighting of lesion-like parts, image display, interpretation report creation support, interpretation report registration request and inspection request to interpretation report server (not shown), and reception from interpretation report server The interpretation report is displayed.

  On the other hand, the image server 3 is obtained by installing a software program for providing a function of a database management system (DBMS) on a general-purpose computer having a relatively high processing capability. The image server 3 includes a large-capacity storage for constructing the image database 4. This storage may be a large-capacity hard disk device connected to the image server 3 by a data bus, or connected to a NAS (Network Attached Storage) or SAN (Storage Area Network) connected to the network 10. It may be a disk device. The image server 3 also has a communication interface that communicates with the modality 1 and the image display device 2 via the network 10. When the image server 3 receives an image registration request from the modality 1, the image server 3 arranges the image in a database format and registers it in the image database 4.

  In the image database 4, the above-described image data of the three-dimensional image and incidental information are registered. The accompanying information includes, for example, an image ID for identifying individual images, a patient ID for identifying a subject, an examination ID for identifying examinations, a unique ID (UID) assigned to each image, and the image Examination date, examination time, type of modality used in the examination to obtain the image, patient information such as patient name, age, gender, examination site (imaging site), imaging information (imaging protocol, (Sequence of imaging, imaging method, imaging conditions, use of contrast agent, etc.) Information such as a series number or collection number when a plurality of images are acquired in one examination can be included.

  When the image server 3 receives a browsing request from the image display device 2 via the network 10, the image server 3 searches the image registered in the image database 4 and transmits the extracted image to the requesting image display device 2. .

  When a user such as an image interpretation doctor performs an operation for requesting viewing of an image to be interpreted, the image display device 2 transmits a viewing request to the image server 3 and acquires an image necessary for interpretation. The image display device 2 executes various image processes on the image and displays the image.

  Next, image display on the display 22 of the image display device 2 will be described with reference to FIG. One “examination” described below belongs to one “patient”. One “inspection” is composed of a plurality of “series”, and one “series” is composed of a plurality of “images”.

  When the user (operator) selects “inspection” from an inspection list (not shown) displayed on the display 22, an image display screen as shown in FIG. 4 is displayed on the display 22. As an example, the image display screen includes an examination list display area 22a arranged at the upper left, a thumbnail display area 22b arranged at the right side thereof, and an image display area 22c arranged below them.

  A list of examinations related to the patient is displayed in the examination list display area 22a. When an examination is selected on this list, the thumbnail display area is updated. In the thumbnail display area 22b, one thumbnail image of a series belonging to “examination selected in the examination list” is displayed.

  When one of the thumbnail images is selected and dragged and dropped onto the series display frame in the image display area 22c, the drag-source series including the thumbnail image is displayed in the drop-down series display frame. Is displayed.

  The image display area 22c includes a plurality of series display frames. One series is displayed in each series display frame. In the example of FIG. 4, four series are displayed in a 2 × 2 layout.

  Next, a specific operation for image interpretation will be described. The operator interprets images while performing an operation on each series displayed in the image display area 22c, that is, an operation for changing the gradation and the enlargement ratio. Operations for each series are performed mainly by clicking or dragging the mouse 24. In this click or drag operation, a function assigned to the button 24a or 24b of the mouse 24 is executed. The operation for this assignment will be described in detail later. In the following, functions that can be assigned to mouse buttons and specific display operations of each function will be described.

"tone"
When this gradation function is set, the gradation center value of the window changes when the mouse 24 is dragged up and down (for example, dragging with the left button 24a pressed). That is, the brightness of the display image changes. On the other hand, when the mouse 24 is dragged left and right, the gradation width of the window changes. That is, the contrast of the display image changes. FIG. 5 and FIG. 6 respectively show display image examples before and after the drag operation when this function is set.

《Enlarge》
When the enlargement function is set, when the mouse 24 is dragged up and down, the enlargement ratio of the display image changes. FIG. 7 and FIG. 8 respectively show display image examples before and after the drag operation when this function is set.

《Movement》
When this movement function is set, when the mouse 24 is dragged, the display image moves (pans) along the drag direction. FIG. 9 and FIG. 10 respectively show display image examples before and after a drag operation (the drag direction is the direction of the arrow attached to FIG. 10) when this function is set.

"paging"
When the paging function is set, when the mouse 24 is dragged up and down, the display image of the series is switched to the previous and next images so as to turn the page one by one. FIGS. 11 to 14 show examples of display images paged by a drag operation when this function is set.

<Select area>
When this area selection function is set, when the start point / end point is designated by dragging the mouse 24, the designated rectangular area is selected as in the area selection in general paint software. FIG. 15 shows an example of a display image in which an area is selected by this function.

<Pixel value>
When this pixel value function is set, when the mouse 24 is clicked (for example, the left button 24a is clicked), an annotation indicating the pixel value is given. FIG. 16 shows an example of a display image to which an annotation indicating a pixel value is given by this function.

"distance"
When the distance function is set, when the start point / end point is designated by dragging the mouse 24, an annotation indicating the distance between the two points is given. FIG. 17 shows an example of a display image to which an annotation indicating a distance is given by this function.

《Oval ROI》
When the ellipse ROI function is set, when the start point / end point is designated by dragging the mouse 24, an annotation indicating the ellipse ROI, the area of the ellipse ROI, the average value of the pixel values, and the like is given. FIG. 18 shows a display image example to which an annotation indicating an ellipse ROI or the like is given by this function.

《Rectangular ROI》
When the rectangle ROI function is set, when the start point / end point is designated by dragging the mouse 24, an annotation indicating the rectangle ROI, the area of the rectangle ROI, the average value of the pixel values, and the like is given. FIG. 19 shows an example of a display image to which an annotation indicating a rectangular ROI or the like is given by this function.

《Select and edit annotations》
When this annotation selection and editing function is set, when the displayed annotation is clicked with the mouse 24, the clicked annotation is selected. FIG. 20 and FIG. 21 show examples of display images before and after the click operation when this function is set, respectively. In this example, as shown in FIG. 21, a region including the selected annotation is indicated by a rectangular frame. Such a frame is preferably displayed in a clear color such as red.

  If the annotation selection and editing functions are set, the annotation is edited by dragging the displayed annotation with the mouse 24. Specific examples of this “editing” include movement of position and change of shape. FIG. 22 and FIG. 23 show examples of display images before and after the drag operation when this function is set, respectively. In this example, the lower right portion of the annotation indicating the rectangle ROI is dragged to reduce the size of the rectangle.

  It should be noted that the image display device 2 may be appropriately provided with a function that is executed by an operation other than the click or drag operation of the mouse 24 as described above. Examples of such functions include functions such as “Delete annotation”, “Copy to clipboard”, and “Customize”.

  The << deletion of annotation >> function is a function for deleting the annotation selected by the “select and edit annotation” function described above. The << copy to clipboard >> function is a function for copying the image data of the area selected by the above-mentioned "area selection" function to the clipboard. The << Customize >> function is a function for displaying a screen (not shown) for customizing various settings and changing the settings of shortcut keys for executing each function on the screen.

  Next, a method for assigning functions to the mouse 24 will be described. In the present embodiment, the following two types of methods can be applied to assign functions to the buttons of the mouse 24.

(1) Select a right-click menu item.

(2) A specific shortcut key on the keyboard 23 is pressed.

  Note that the function assignment described below is made based on a predetermined program by the processing device 21 shown in FIG. That is, in this embodiment, the processing device 21 constitutes a mouse function control unit.

[Setting of the first mode by the method (1)]
First, the method (1) will be described. When the mouse 24 is right-clicked on the display image of the display 22 shown in FIG. 2, for example, a right-click menu as shown in FIG. 24 is displayed. When the function is assigned to the mouse button from the right-click menu, the processing device 21 sets the first mode described above for the mouse operation. That is, when the “gradation” in the right-click menu shown in FIG. 24 is selected with the mouse cursor, for example, when the left button 24a of the mouse 24 is clicked, the above-described “gradation” function is assigned to the mouse button The first mode is set.

  In this case, the gradation of the image can be changed by dragging the mouse 24 (for example, dragging with the left button 24a pressed). Since the first mode is set, the << gradation >> function is kept assigned to the mouse button even after the mouse button (for example, the left button 24a) is released. Therefore, when it is desired to change the gradation continuously, the above drag operation may be repeated. As described above, in the first mode, the number of operations when it is desired to continuously execute one function a plurality of times can be reduced.

  Thereafter, in order to assign a function other than << gradation >> to the mouse button, another desired function may be assigned by using the right click menu or using a shortcut key described later.

[Setting of the first mode by the method (2)]
Next, the method (2) will be described. According to this method, both the first mode and the second mode described above can be set. First, the case where the first mode is set will be described. In this embodiment, as an example, when a specific shortcut key on the keyboard 23 is pressed and released, the first mode is set.

  Specifically, a case where the above << Grayscale >> function is assigned will be described. In this case, it is assumed that the aforementioned “enlargement” function is assigned as a default function to the mouse button. Under this state, when the “W” key, for example, of the keyboard 23 used as a shortcut key is pressed, the “gradation” function is assigned to the mouse button and the first mode is set.

  Therefore, also in this case, the gradation of the image can be changed by dragging the mouse 24. Since the first mode is set, the “gradation” function is kept assigned to the mouse button even after the mouse button is released. Therefore, when it is desired to change the gradation continuously, the above drag operation may be repeated. In this case as well, the number of operations when one function is continuously executed a plurality of times can be reduced.

  After this, to assign a function other than “Gradation” to the mouse button, use another shortcut key that is not the “W” key, or use the right-click menu to select another desired function. Can be assigned.

[Setting of second mode by method (2)]
Next, a case where the second mode is set by the method (2) will be described. In the present embodiment, as an example, when the mouse 24 is clicked or dragged while a specific shortcut key on the keyboard 23 is pressed, the second mode is set.

  Specifically, a case where the above << Grayscale >> function is assigned will be described. In this case also, it is assumed that the above-mentioned “enlargement” function is assigned as a default function to the mouse button. In this state, if the “W” key of the keyboard 23 that is used as a shortcut key is held down, the “gradation” function is assigned to the mouse button (for example, the left button 24a) and the second mode is set. Is done. Therefore, when the mouse 24 is dragged while the “W” key is held down, the gradation of the image changes.

  When the mouse button is released while the “W” key is held down, the assignment of the mouse button immediately returns to the immediately preceding function, ie, the “enlarge” function. The “W” key is then released. Accordingly, if the mouse 24 is dragged thereafter, the << enlargement >> function can be used. Even after the mouse button is released after using the "Enlarge" function in a drag operation, the "Enlarge" function remains assigned to the mouse button.

  As described above, according to the second mode, it is possible to reduce the number of operations when it is desired to execute a certain function only once and immediately return to the previous function.

  In the example described above, the “predetermined function” that is returned after executing a predetermined function once is set as the “previous function”, but the “default function” may be set as a predetermined “default function”. Even in this case, it is possible to reduce the number of operations when it is desired to execute a certain function only once and immediately return to the default function.

  By the way, when the image display device 2 is used, it may be desired to execute a specific process corresponding to the current assigned function immediately after using the function assigned to the mouse 24. For example, there are the following situations.

(A) I want to execute the “Copy to Clipboard” function immediately after selecting an area with the “Select Area” function.

(B) If an annotation indicating a rectangular ROI is added with the << Rectangle ROI >> function, it is desired to immediately use the << Select and Edit Annotation >> function.

  In order to cope with these situations, in another embodiment of the present invention, in addition to the first mode and the second mode as described above, the third mode can be set, and the three modes can be switched. Yes. Here, the third mode is a mode in which a specific process is executed subsequently when a predetermined function by the mouse 24 is used once.

  The predetermined function in the third mode and a specific process corresponding thereto can be set on the display screen of the display 22 as shown in FIG. 25, for example. That is, when a tool (function) for which “operation after tool operation” is set on the setting display screen is used, the third mode is set. For example, in the example of FIG. 25, the combination of “Copy to clipboard” is selected as “Area selection” and “Operation after tool operation”, and the “OK” button is clicked in this state. As soon as an area is selected with the << area selection >> function, the third mode in which the << copy to clipboard >> function is executed is set.

  In addition, in the example of FIG. 25, when a function such as << Distance >>, << Angle >>... << Rectangle ROI >> is used, the third mode in which the << Annotation selection and editing >> function is executed immediately is set It is also possible to do.

  In the embodiment described above, the third mode is set with priority over the first mode and the second mode. However, the present invention is not limited to this. For example, the second mode is set with priority over the third mode. May be. That is, when the mouse 24 is operated while a specific shortcut key on the keyboard 23 is pressed, the setting relating to the third mode is ignored, and the operation may always return to the default function.

  As described above, the embodiment configured to set the function related to the image display has been described. However, the method of the present invention can be applied to a case where a function related to a function other than the image display is assigned to the mouse. Even in this case, the above-described effects can be obtained similarly.

  Note that a program for causing a computer to execute the procedure of the function setting method of the information processing apparatus according to the present invention described above is also an embodiment of the present invention. Furthermore, a computer-readable recording medium in which such a program is recorded is one embodiment of the present invention.
