Ultrasonic diagnosing apparatus

摘要

In an ultrasonic diagnosing apparatus of an electronic sector-scanning type in which a target plane in a body is observed by directly contacting a probe with the body surface of a patient, a circuit for setting a depth from the body surface to the target plane has a function to compensate for variations of the depth and the swing angle of the probe arising from the unevenness on the body surface and those of the distance from the probe to the target plane due to a sector-scanning change of the ultrasonic beam.
