ABSTRACT:
A diagnostic ultrasound system comprising an element for detecting a velocity of motion of a tissue, such as a cardiac muscle or a vascular wall, contained in an object at every sampling point in a section of the object and an element for creating two-dimensionally mapped data of the velocity in the section. The system further comprises an element for analyzing a motion state of the tissue on the basis of local velocities falling into a plurality of local regions set on the two-dimensionally mapped data of the velocity and an element for displaying analysis results of the motion state. The velocity detecting element transmits an ultrasonic pulse signal toward the tissue in order to acquire a Doppler shifted echo, according to a pulsed Doppler technique.
