Abstract
There is provided an ultrasonic diagnostic apparatus capable of measuring hardness information of a subject with high time resolution and spatial resolution.The apparatus is provided with a ultrasonic probe 1 and a displacement generation unit 10 configured to displace an inside of a subject and is configured to transmit an ultrasonic beam for displacement detection to a plurality of detection positions of the subject from the ultrasonic probe 1, and to detect a shear wave velocity based on the displacement at the plurality of detection positions in a control unit 3 by using a reflection signal detected in a detection unit 20, thereby outputting hardness information of the subject. The ultrasonic beam for displacement detection is transmitted to one of the plurality of detection positions. A waveform analysis unit 26 of the control unit 3 is configured to perform a change control of analyzing a shear wave resulting from the displacement to thus transmit the ultrasonic beam for displacement detection to another position of the plurality of detection positions. Thereby, it is possible to measure the shear wave velocity with high time resolution and spatial resolution, so that it is p…
