Abstract
The present invention provides an ultrasonic diagnostic apparatus. The ultrasonic diagnostic apparatus comprises an ultrasonic probe ( ) for transmitting ultrasonic pulses into a living body and receiving ultrasonic reflected waves from the living body, a phase-detecting section ( ) for detecting each phase of the ultrasonic reflected waves, and a phase-difference detecting section ( ) for determining a phase difference in the repetition period of the ultrasonic transmitting/receiving operation according to the detected phase signals. The ultrasonic diagnostic apparatus further includes a data analyzing section ( ) for calculating the movement velocity of the living body tissue and the blood flow velocity according to the phase difference of the ultrasonic reflected waves and tracking the movements of the living body tissue and the blood according to the movement values calculated by the velocities, and a display section ( ) for displaying the tracked results and the movement value and velocity waveform of the living body tissue and the blood simultaneously through a display control section ( ).
