摘要:
The present invention aims at providing an ultrasonic diagnostic apparatus capable of displaying a stable spatial distribution of elastic characteristics for each hear beat without depending on the accuracy or stability of measurement of blood pressure and without involvement of measurement of blood pressure.In an ultrasonic diagnostic apparatus of the present invention, an ultrasonic reflected wave transmitted from an ultrasonic probe 13 and reflected by biomedical tissue is input to a computing section 19 by way of a receiving section 15, a delay time control section 16, a phase detection section 17, and a filter section 18. In accordance with the phase detection signal acquired from the phase detection section 17, the computing section 19 computes 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 section 21.
