Explanatory drawing which shows the example of a display of the conventional ultrasonic diagnostic apparatus

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing a display example of an embodiment of an ultrasonic diagnostic apparatus according to the present invention. The display screen shown in FIG. 1 includes an ultrasonic image area A1 where the ultrasonic image P is displayed and a display content change button for selecting the change content of the ultrasonic image P (for example, Fov in the drawing). , Pos, ROI, Dop) (hereinafter sometimes simply referred to as a button) is divided into an operation component display area A2, which differs from the prior art in the following points.

  First, only the ultrasonic image P is displayed in the ultrasonic image area A1, and the ultrasonic image P does not change even when touched for image change according to the present invention. The ultrasonic image area A1 may not have a touch panel, but may have a touch panel for other uses. Furthermore, the operation component display area A2 has a touch panel, and when the displayed content change buttons (Fov, Pos, ROI, Dop in the figure) are selectively touched and dragged with the finger F, the device side The display image P in the ultrasonic image area A1 is changed according to the selected change content and the drag direction. However, even if another button b is touched during this dragging, the touch operation is invalidated on the device side. For this reason, it is possible to prevent the ultrasonic image region A1 from becoming dirty due to fingerprints or scratches, and to make it easier to see the ultrasonic tomographic image.

Here, an example of a button for changing the display image P in the ultrasonic image area A1 in FIG. 1 will be described.
(1) Fov (Field of View): The angle of the display image P in the ultrasonic image region A1 in the one-dimensional scanning direction is changed.
(2) Pos (Position): The position of the display image P in the ultrasonic image area A1 in the one-dimensional scanning direction is changed.
(3) ROI (Region of Interest): The size and position of the display image P in the ultrasonic image region A1 in the two-dimensional direction are changed, or color display is performed.
(4) Dop: The position of the Doppler sampling gate of the display image P in the ultrasonic image area A1 is moved.

  FIG. 1 shows an operation when the position of the Doppler / sampling gate G of the display image P in the ultrasonic image area A1 in (4) is moved, and the Dop button displayed in the operation component display area A2 is touched. It shows a case where it is dragged in the right direction. Here, since the Dop button is set with a rule so that the position of the Doppler sampling gate G is moved in that direction when dragged in the left-right direction in advance, on the device side based on this rule, The position of the Doppler sampling gate G of the display image P in the ultrasonic image area A1 is moved according to the drag direction. Further, the button b is touched as a button of another function during the dragging, but the touch operation of the button b is invalidated. Therefore, the button b can be dragged from the position of the Dop button. Further, when the touch panel is not touched during the dragging, it is determined that the operation of the Dop button is finished, and the touch operation of the button b which has been invalidated is validated. As a rule to be set for each button, a change operation rule such as moving the target image left and right and up and down, enlarging or reducing the width or the entire image can be set.

  2 and 3 show other display examples of buttons in the operation component display area A2. FIG. 2 shows an operation when the position of the display image P in the ultrasonic image area A1 in (2) is changed in the one-dimensional scanning direction, and the POS button displayed in the operation component display area A2 is touched. When dragged in the horizontal direction, the apparatus changes the position of the display image P in the ultrasonic image area A1 from the position indicated by the dotted line to the position indicated by the solid line according to the drag direction. FIG. 3 shows an operation when the angle in the one-dimensional scanning direction of the display image P in the ultrasonic image area A1 in (1) is changed, and the FOV button displayed in the operation component display area A2 is touched. When dragging in the horizontal direction, dragging in the right direction is ruled as “angle expansion” and dragging in the left direction as “angle reduction”. On the device side, the ultrasound image area A1 is selected according to the drag direction. The angle (fan-shaped opening angle) of the display image P is changed. In FIG. 3, since it is dragged in the left direction, it is changed from a fan shape having a large opening angle (wide) shown by a dotted line to a fan shape having a small opening angle (narrow) shown by a solid line. Here, since the drag direction of the POS button and the FOV button is only in the horizontal direction of the display image in the ultrasonic image area A1, they are arranged in the horizontal direction at the lower end of the screen as an example.

  FIG. 4 shows another display example of buttons in the operation component display area A2, and a Focus button for changing the focus position of the display image P in the ultrasonic image area A1 and the depth of the display image P in the ultrasonic image area A1. A Depth button for changing the depth and a Zoom button for zooming the display image P in the ultrasonic image area A1 are provided, and the drag direction of these buttons is perpendicular to the display image in the ultrasonic image area A1. Since it is only the direction, as an example, it is arranged in the vertical direction at the right end of the screen. Here, the arrangement position of these buttons is the ultrasonic image area A1 in which the buttons are not normally arranged. However, the area where the ultrasonic image P is not displayed is determined and can be switched using the dedicated key. Is shown. (This right end surface of the display device may be fixed to the operation component display area from the beginning.) As shown in FIG. 4, when the Focus button is touched and dragged in the vertical direction, the device side drags. The focus position of the display image P is changed according to the direction, and the focus mark is moved.

  FIG. 5 is a block diagram showing the configuration of an ultrasonic diagnostic apparatus that executes the above display control. First, the display device with a touch panel includes a display device 4 and a touch panel 5. The ultrasonic control unit 2 controls ultrasonic transmission of the ultrasonic probe 1 and reception of the reflected signal. The display control unit 3 processes the received reflected signal and displays an ultrasonic image in the ultrasonic image area A1 of the display device 4 as shown in FIGS. Display control for displaying in the area A2 is executed. The input control unit 6 detects the touch position of the touch panel 5, and the ultrasonic control unit 2 changes the image of the ultrasonic image area A 1 of the display device 4 according to the touch position of the touch panel 5 detected by the input control unit 6. Control for.

  FIG. 6 is a flowchart for explaining the display control. First, a touch detection process is executed (step S1), and if not touched, the process returns from step S2 to step S1, while if touched, the process proceeds from step S2 to step S3. In step S3, the touch position is detected, and then it is checked whether or not the touch detection position is a draggable region (step S4). If it is a draggable area, the touch panel operation other than the display content change button is prohibited (step S5), and then the operation content is selected as the change content of the display content change button touched for the operation (step S6). .

  Next, in order to monitor the touch state, the touch detection function is first activated (step S7), and if touched, the process proceeds from step S8 to step S9. In step S9, the movement distance of the touch position is detected, and if there is a movement, the process proceeds from step S10 to step S11, the display change value corresponding to the movement distance is changed (display state change), and then the process returns to step S7. If there is no movement in step S10, the process returns to step S7. If it is not touched in step S8, the display change is canceled (step S12), then touch panel operations other than the display change button are permitted (step S13), and then the process returns to step S1. If the area is not a draggable area in step S4, a touch detection process is executed (step S14). If not touched, the process returns from step S15 to step S1, while if touched, the process proceeds from step S15 to step S14. Note that the timing for changing the display state as described above is not only performed in real time in accordance with the movement of the touch position, but may also be changed after the movement of the touch position is completed.

  Note that each functional block used in the description of the above embodiment is typically realized as an LSI which is an integrated circuit. These may be individually made into one chip, or may be made into one chip so as to include a part or all of them. The name used here is LSI, but it may also be called IC, system LSI, super LSI, or ultra LSI depending on the degree of integration. Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after manufacturing the LSI, or a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used. Further, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology or a derivative other technology, it is naturally also possible to carry out function block integration using this technology.

  The present invention can prevent a display portion of an ultrasonic tomographic image displayed on a display device with a touch panel from being smudged with fingerprints or scratches when the display content of the ultrasonic tomographic image is changed by a drag operation. As a result, the ultrasonic tomographic image can be easily seen and can be used for an ultrasonic diagnostic apparatus.
