  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 is divided into an ultrasonic image area A1 where the ultrasonic image P is displayed and an operation component display area A2 for dragging the ultrasonic image P, as in the prior art. First, in the ultrasonic image area A1, which is the first display area of the present invention, only the ultrasonic image P and the cursor C are displayed, and the cursor C does not move even when touched. The ultrasonic image area A1 may not have a touch panel, but may have a touch panel for other uses.

  Further, the operation component display area A2 as the second display area has a touch panel, and includes a touch pad area 100 for moving the cursor C, a start button 101, a set button 102, Next button 103, button 104 for other modes, and the like are displayed. When the touch pad area 100 is dragged with the finger F, the apparatus moves the cursor C according to the drag direction and the drag distance (C1 → C2 in the figure). For this reason, it is possible to prevent the ultrasonic image area A1 from becoming dirty due to fingerprints or scratches, and to make the ultrasonic tomographic image P easier to see.

  As shown in FIG. 2, by displaying the finger image 100a in the touch pad area 100, it is possible to alert the user not to drag the ultrasonic tomographic image P. In addition, assuming that the operator touches the ultrasonic image area A1 by mistake, if the ultrasonic image area A1 is touched, “Do not touch the ultrasonic image area A1 on the display screen. By displaying a warning message such as “to be performed in the operation component display area A2” or by causing the operation component display area A2 to blink or change the brightness to warn the operator and call attention. It is possible to prevent the display portion of the ultrasonic tomographic image from being smudged with fingerprints or scratches, and to make the ultrasonic tomographic image easier to see. Furthermore, when the drag operation is started, the operator's identification information is input. If the same operator erroneously touches the ultrasonic image area A1 a plurality of times during a predetermined period, the warning level ( The attention may be further increased by increasing the frequency of blinking and the amount of change in luminance.

  Here, the drag operation is not only valid within the touchpad area 100 but also valid outside the touchpad area 100 as shown in FIG. At this time, when a button 104 for another mode is touched while dragging outside the touch pad area 100, the touch operation of the button 104 for another mode is disabled and the drag operation is enabled. When the drag operation ends, the touch operation of the button 104 for another mode in which the touch operation is invalidated is validated.

  As an application for moving the cursor C displayed in the ultrasonic image area A1, there is a case where the fetal image is displayed in the ultrasonic image area A1 to measure the diameter of the head of the fetus. The cursor C designates both ends (start point and end point) of the head. When both ends of the head are designated, both ends of the head are measured based on the relationship with the size of the fetal image and displayed as 105 (xxxxmm) in FIG.

  FIG. 3 is a block diagram showing a configuration of an ultrasonic diagnostic apparatus that executes the above-described measurement control. First, the display device with a touch panel includes a display device 4 and a touch panel 5. The ultrasonic transmission / reception unit 2 controls the ultrasonic transmission of the ultrasonic probe 1 and the reception of the reflection signal thereof, and the signal processing unit 3 processes the received reflection signal to generate an ultrasonic image as shown in FIG. P is displayed in the ultrasonic image area A1 of the display device 4, and display control for displaying various operation buttons in the operation component display area A2 is executed based on the control of the screen display control unit 13. The control unit 10 includes an input information control unit 11, a calculation unit 12, and a screen display control unit 13. The input information control unit 11 receives user operation information (event) from the touch panel 5 and the operation panel 6 and processes the information. In particular, when both ends of the head of the fetal image are designated by the cursor C, the calculation unit 12 measures the both ends of the head based on the relationship with the size of the fetal image and displays the measurement result. 13 is instructed.

  FIG. 4 is a flowchart for explaining the processing of the arithmetic unit 12 that executes the above-described measurement control. The process shown in FIG. 4 starts when the start button 101 is touched. First, it is checked whether or not the set button 102 is touched (ON) (step S1), and touch (ON). Then, the current position of the cursor C is stored as a starting point (step S2). Next, it is also checked whether or not the Set button 102 has been touched (ON) (step S3). If touched (ON), the current position of the cursor C is stored as the end point (step S4), and then The distance between the start point and the end point of the ultrasonic image P is measured (step S5). Further, it is checked whether or not the next button 103 has been touched (ON) (step S6). When the next button 103 is touched (ON), the process returns to step S1 to measure the distance of other parts.

  As another example of the drag operation, the cursor movement can be continued when the drag continues at the edge of the touch pad area 100 with the inside of the touch pad area 100 as the drag start position as shown in FIG. Further, as shown in FIG. 6, it is possible to trace the inside of the touch pad area 100 with a finger a plurality of times in the same direction.

  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. For example, biotechnology can be applied.

  According to the present invention, when an ultrasonic tomographic image displayed on a display device with a touch panel is dragged, it is possible to prevent the display portion of the ultrasonic tomographic image from becoming dirty due to fingerprints or scratches. This has the effect of making it easy to see the tomographic image, and can be used in an ultrasonic diagnostic apparatus or the like.
