Patent ID: 8343052

Claim:
An ultrasonic diagnostic apparatus, comprising: an ultrasonic probe; a transceiver configured to transmit and receive an ultrasonic wave to and from the ultrasonic probe; an image creating part configured to create image data of a series of tomographic images in time series for each of two or more sectional positions of a biological tissue on the basis of a received signal obtained as a result of transmitting and receiving the ultrasonic wave; a display part configured to display one tomographic image from among the series of tomographic images on the basis of the image data created for each of the two or more sectional positions; a designating part configured to designate a measurement image region on the one displayed tomographic image for each of the two or more sectional positions; and a calculator configured to calculate local motion information showing a motion state of the biological tissue in the designated measurement image region on the basis of the image data of the series of tomographic images for each of the two or more sectional positions, and configured to calculate motion information showing the motion state of the biological tissue on the basis of the local motion information calculated for each of the two or more sectional positions, wherein the local motion information indicates a time series displacement of the one tomographic image in a same measurement image region, the motion information indicates a difference of the local motion information between the two or more sectional positions, which are different sectional positions relating to different cross sections of the biological tissue, and the display part displays the motion information calculated by the calculator.
