ABSTRACT:
The present invention aims at providing an ultrasonic diagnostic apparatus capable of displaying a stable spatial distribution of elastic characteristics for each heart beat without depending on the measurement of blood pressure and the accuracy or stability of such measurement, where an ultrasonic wave transmitted from an ultrasonic probe13and reflected by biomedical tissue is input to a computing section19by way of a receiving section15,a delay time control section16, phase detection section17and filter section18. In accordance with the phase detection signal acquired from the phase detection section17,the computing section19computes a relative elastic characteristic which is an elastic characteristic normalized by an elastic characteristic of an arbitrary reference area in the biomedical tissue. A distribution of relative elastic characteristics computed by the computing section is displayed on a display section21.
