Description

  The present invention relates to a medical image display system and program.

  In recent years, the incidence of breast cancer in women has been increasing. Breast cancer is a disease with a high cure rate if detected early, and regular screening is recommended for early detection. In order to improve the detection rate of breast cancer, it is said that it is effective to perform overreading on an X-ray image of the breast. Overreading means that a second doctor interprets a medical image obtained by imaging a patient after the first doctor interprets it. However, at present, in breast cancer screening, the number of doctors who interpret breast images is absolutely insufficient, and it is actually impossible to perform sufficient screening.

  Under such circumstances, computer-aided diagnosis (CAD) has appeared due to the development of computer technology. This function is a function that analyzes a digitally taken medical image (mainly a CR image), adds an annotation to a region that appears to be a lesion, displays it on a display, and helps a doctor interpret the image. For a breast image, an abnormal shadow candidate region that may be a lesion such as a tumor or microcalcification is detected. The effectiveness of CAD has been confirmed in digital image diagnosis, and products are provided by various manufacturers.

  For example, in an image processing method for displaying a medical image by marking a portion that matches a predesignated condition, a method that enables selection of display / non-display of each mark has been proposed (see Patent Document 1). . Conditions include, for example, marking all suspicious parts such as malignant tumors, marking only parts with higher malignancy, marking only parts with the highest malignancy, and the like.

  In general, when displaying / hiding the CAD result in a state where the CAD result indicating the position of the abnormal shadow candidate is displayed on the medical image, the CAD result is displayed / hidden from the menu on the operation screen. The user must explicitly instruct to display / hide the CAD result, such as selecting or inputting an instruction to that effect from the keypad.

JP 2004-159739 A

  However, when the CAD result is displayed on the medical image, there is a possibility that the lesioned part and the CAD result may overlap when the interpretation is actually performed. When the lesioned part and the CAD result overlap, it is necessary to perform interpretation while hiding the CAD result, which causes a troublesome work for the user and a problem of reducing the interpretation efficiency.

  The present invention has been made in view of the above problems in the prior art, and an object thereof is to improve the interpretation efficiency of medical images.

When the zoom mode is selected on the operation screen while the medical image is displayed on the display unit 43, an operation for enlarging or reducing the medical image becomes possible. The zoom mode is a mode for enlarging or reducing a medical image.

  Specifically, when enlarging a medical image, the user moves the mouse forward (in a direction away from the user) with the left button of the mouse down. On the other hand, when reducing the medical image, the user moves the mouse backward (in a direction approaching the user) with the left button of the mouse down. The control unit 41 executes a medical image enlargement / reduction process in accordance with the amount of movement of the mouse in the front-rear direction, from the mouse down operation to the up operation.

Next, the operation will be described.
FIG. 5 is a flowchart showing a medical image display process A executed in the client terminal 40. This process is realized by software processing in cooperation with the CPU of the control unit 41 and the image viewer program 461 stored in the storage unit 46.

  First, an image file D1 of a medical image to be interpreted is selected by a user's operation from the operation unit 42, and the selected medical image is transmitted to the image server device 30 by the communication unit 44 under the control of the control unit 41. An acquisition request for the image file D1 of the image is transmitted. Then, the control unit 41 acquires the medical image image file D1 and the CAD result file D2 associated with the image file D1 from the image server device 30 via the communication unit 44, and loads them onto the memory 47. . Next, the control unit 41 displays the medical image on the display unit 43 based on the medical image image file D1. Here, the zoom mode is selected by an operation from the operation unit 42 by the user.

  After the zoom mode is selected, the control unit 41 determines whether or not a mouse down event of the left mouse button has been acquired based on an operation signal output from the operation unit 42 (step S1). Until the mouse down event of the left button of the mouse is acquired, it is in a standby state.

  When the mouse down event of the left mouse button is acquired (step S1; YES), the control unit 41 displays the CAD result on the medical image displayed on the display unit 43 based on the CAD result file D2. (Step S2). Specifically, the control unit 41 adds and displays a mark at the position of the abnormal shadow candidate on the medical image displayed on the display unit 43.

  Next, the control unit 41 determines whether or not the mouse has moved in the front-rear direction based on the operation signal output from the operation unit 42 (step S3). When the mouse has moved in the front-rear direction (step S3; YES), the control unit 41 executes a medical image enlargement / reduction process (step S4). Specifically, the control unit 41 acquires the movement direction and movement amount of the mouse in the front-rear direction based on the operation signal output from the operation unit 42. When the mouse is moved forward (in the direction away from the user), the control unit 41 calculates the enlargement ratio of the medical image according to the amount of movement of the mouse, and the mouse moves backward (in the direction approaching the user). In such a case, the reduction rate of the medical image is calculated according to the amount of movement of the mouse by the control unit 41. Next, the medical image is enlarged according to the calculated enlargement rate or reduction rate by the control unit 41. Alternatively, the image is reduced and displayed on the display unit 43, and the mark added to the position of the abnormal shadow candidate on the medical image is also enlarged or reduced according to the same enlargement rate or reduction rate.

  When there is no movement of the mouse in the front-rear direction in step S3 (step S3; NO), or after step S4, the control unit 41 outputs the mouse of the left button of the mouse based on the operation signal output from the operation unit 42. It is determined whether an up event has been acquired (step S5). When the mouse up event of the left button of the mouse is not acquired (step S5; NO), the process returns to step S3, and the processes of steps S3 to S5 are repeated.

When the mouse up event of the left mouse button is acquired in step S5 (step S5; YES), the CAD result (mark) on the medical image displayed on the display unit 43 is not displayed by the control unit 41. Only the medical image is displayed on the display unit 43 (step S6).
Thus, the medical image display process A ends.

  6A to 6C show examples of medical images (breast images) displayed on the display unit 43. FIG. 6A is a medical image before enlargement, FIG. 6B is a medical image during enlargement processing, and FIG. 6C is a medical image after enlargement.

  As shown in FIG. 6A, the CAD result is not displayed on the medical image before enlargement. When the down operation of the left mouse button is performed in the state shown in FIG. 6A, a mark M1 indicating the position of the abnormal shadow candidate is displayed on the medical image as shown in FIG. 6B.

  When the mouse is moved forward while the left button of the mouse is pressed, the medical image is enlarged according to the movement amount. As the medical image is enlarged, the mark M1 displayed on the medical image is also enlarged.

  If the left button of the mouse is operated while the mark M1 is displayed, the mark M1 on the medical image is not displayed. The mark M1 is displayed on the medical image from FIG. 6 (a) to FIG. 6 (c) through FIG. 6 (c), that is, from the mouse down operation to the up operation. After the operation for enlarging the image, only the medical image is displayed.

  As described above, according to the medical image display system 100 in the first embodiment, the client terminal 40 marks the position of the abnormal shadow candidate on the medical image during the operation to change the display target area. After the operation for changing the display target area is completed, only the medical image is displayed on the display unit 43, so that the interpretation efficiency of the medical image can be improved.

  Specifically, in the client terminal 40, the mouse down event is used as a cue to start the enlargement / reduction process, the enlargement / reduction process is performed using the amount of movement of the mouse in the front-rear direction, and the mouse up event is terminated. The signal is as follows. As described above, the enlargement / reduction processing of the medical image is performed according to the operation on the mouse, and the display / non-display control of the CAD result is performed. Therefore, the CAD result can be displayed or hidden at an appropriate timing. While the medical image enlargement / reduction process is being performed, the CAD result can be displayed to alert the interpretation doctor, while after the medical image enlargement / reduction process is completed, the CAD result is not displayed. , It is possible to prevent the display of the CAD result from overlapping the lesioned part or the like.

[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described.
Since the medical image display system in the second embodiment has the same configuration as the medical image display system 100 shown in the first embodiment, FIGS. 1 to 4 are used, and the configuration is illustrated and described. Description is omitted. Hereinafter, a configuration and processing characteristic of the second embodiment will be described.

  As an example of changing the display target area displayed on the display unit 43 in the medical image performed in the client terminal 40, an operation method for moving the display target area will be described. The movement of the display target area refers to moving the display target area in the plane of the medical image. When the pan mode is selected on the operation screen while the medical image is displayed on the display unit 43, an operation for moving the display target area in the medical image is possible. The pan mode is a mode for moving the display target area in the medical image.

  Specifically, when moving a medical image, the user moves the mouse forward / backward / left / right with the left button of the mouse down. The control unit 41 executes a movement process of the display target area in the medical image according to the moving direction and the moving amount of the mouse during the mouse down operation to the up operation. For example, when the user moves the mouse to the right with the left button of the mouse down, the display target area in the medical image moves to the right. In addition, when the user moves the mouse forward (in a direction away from the user) with the left button of the mouse down, the display target area in the medical image moves up.

Next, the operation will be described.
FIG. 7 is a flowchart showing the medical image display process B executed in the client terminal 40. This process is realized by software processing in cooperation with the CPU of the control unit 41 and the image viewer program 461 stored in the storage unit 46.

Then, the control unit 41 acquires the medical image image file D1 and the CAD result file D2 associated with the image file D1 from the image server device 30 via the communication unit 44, and loads them onto the memory 47. . Next, the control unit 41 displays the medical image on the display unit 43 based on the medical image image file D1. Here, the pan mode is selected by an operation from the operation unit 42 by the user.

  After selecting the pan mode, the control unit 41 determines whether a mouse down event of the left mouse button has been acquired based on the operation signal output from the operation unit 42 (step S11). Until the mouse down event of the left button of the mouse is acquired, it is in a standby state.

  When the mouse down event of the left mouse button is acquired (step S11; YES), the control unit 41 displays the CAD result on the medical image displayed on the display unit 43 based on the CAD result file D2. (Step S12). Specifically, the control unit 41 adds and displays a mark at the position of the abnormal shadow candidate on the medical image displayed on the display unit 43.

  Next, the control unit 41 determines whether or not the mouse has moved based on the operation signal output from the operation unit 42 (step S13). If the mouse has moved (step S13; YES), the control unit 41 executes a process for moving the display target area in the medical image (step S14). Specifically, the control unit 41 acquires the movement direction and the movement amount of the mouse based on the operation signal output from the operation unit 42. Then, the display target area after movement is calculated by the control unit 41 according to the movement direction and movement amount of the mouse. Next, the calculated display target area is displayed on the display unit 43 by the control unit 41, and the mark added to the position of the abnormal shadow candidate on the medical image is similarly moved and displayed.

  When there is no movement of the mouse in step S13 (step S13; NO), or after step S14, a mouse up event of the left button of the mouse is performed by the control unit 41 based on the operation signal output from the operation unit 42. It is determined whether or not it has been acquired (step S15). When the mouse up event of the left button of the mouse is not acquired (step S15; NO), the process returns to step S13, and the processes of steps S13 to S15 are repeated.

When a mouse up event of the left mouse button is acquired in step S15 (step S15; YES), the CAD result (mark) on the medical image displayed on the display unit 43 is not displayed by the control unit 41. Only the medical image is displayed on the display unit 43 (step S16).
Thus, the medical image display process B ends.

  8A to 8C show examples of medical images (breast images) displayed on the display unit 43. FIG. FIG. 8A shows a medical image before movement, FIG. 8B shows a medical image during movement processing, and FIG. 8C shows a medical image after movement.
