ABSTRACT:
An ultrasonic diagnosis system comprising a variable setting arrangement including an ultrasonic transducer array for transmitting a pulse-like ultrasonic wave to an object and detecting a reflection wave from the object, and assuming the acoustic velocity of the object; a control arrangement for determining the depth of electronic focusing in accordance with this assumed acoustic velocity; and a display for displaying the assumed acoustic velocity. The ultrasonic diagnosis system determines whether the reflection signal of the object at a predetermined position is in-focus or out-of-focus and knows the actual acoustic velocity of the object from the assumed acoustic velocity when the reflection signal is in-focus.
