ABSTRACT:
A plurality of ultrasonic pulses are transmitted to the inside of a living body by an ultrasonic probe and an ultrasonic echo signal is received from within the living body. An auto-correlating unit effects auto-correlation processing on the ultrasonic echo signal to produce a real-part component and an imaginary-part component. A real-part component corrector adds an offset value to the real-part component so as to generate a new real-part component. A velocity detector detects a moving velocity of a tissue or blood from the new real-part component and the imaginary-part component.
