Since the observation monitor for this purpose is semi-fixedly installed on the main body of the device, even if the observation monitor is rotated, the observation monitor will be separated from the doctor, so the doctor should make a diagnosis while looking into the position. There was a problem that I had to do. In obstetrics and gynecology, there is also a request to show the fetus to a pregnant woman lying on the bed, but in order for the pregnant woman to see the observation monitor, the observation monitor should be rotated toward the pregnant woman's face. It was very inconvenient because I had to wake up my upper body. Therefore, it is an object of the present invention to allow a doctor and a patient to easily view an observation monitor even during ultrasonic diagnosis.

[0004]

In order to achieve the above object, according to the present invention as set forth in claim 1, ultrasonic waves are applied to a region to be inspected by a probe for transmitting and receiving ultrasonic waves, and the intensity of the reflected waves thereof.
