I have. With respect to these ultrasonic image diagnostic apparatuses, further improvements in convenience and operability are demanded by doctors and clinical laboratory technicians who are operators.

To meet these demands, various techniques have been applied to conventional ultrasonic diagnostic imaging apparatuses. Especially with the rapid spread of ultrasonic diagnostic imaging equipment in recent years,
Ultrasound imaging has come to be used routinely in medical settings. In particular, diagnostic methods based on blood flow information by the ultrasonic Doppler measurement method are rapidly spreading with the spread of ultrasonic image diagnostic apparatuses having a Doppler measurement function.

[0004] As one of the diagnostic methods based on such an ultrasonic Doppler measurement method, a B-mode image of a diagnostic site is displayed, and a position to be measured on an ultrasonic tomographic image in the B-mode is designated. There is a measurement function to measure the cardiac output at a specified position.

This measurement function is performed as one of so-called ultrasonic echo examinations, and is, for example, a TCS (Touch Command Scr) provided on a console of an ultrasonic diagnostic imaging apparatus.
The inspection function is selected via the display panel of FIG. In the TCS, the inspection function is displayed as a menu so that the operator can select it, and is called a TCS menu. When the operator touches the name of a desired inspection function in the displayed TCS menu with a finger, the contact is electrically detected and the inspection function is selected. In addition, by using a trackball provided on the console, each part is measured by rolling the trackball and tracing around the measured part while looking at the measured part displayed on the monitor.

[0006]

However, the prior art has the following problems to be solved.

[0007] The method using a trackball while watching the monitor has a problem such as blurring at the time of tracing.

When displaying the measurement results on a screen,
When the number of measurement sites increases, the measurement results occupy the screen, hiding images and hindering diagnosis.

Further, when printed for pasting on a medical chart, an adverse effect is caused such that an image becomes difficult to see.

In view of these problems, the present invention can easily measure a measurement site, can switch and display a measurement screen and a monitor screen, and can reduce the time required for diagnosis. It is an object to provide a diagnostic device.
