ULTRASONIC DIAGNOSTIC DEVICE AND CONTROL PROGRAM THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device which allows an operator to recognize deviation between a sound ray direction of an ultrasonic wave and a movement direction of a biological tissue.SOLUTION: An ultrasonic diagnostic device comprises: a distortion calculation part which calculates distortion in the sound ray direction of the ultrasonic wave being distortion of each portion in the biological tissue on the basis of two echo signals on the same sound ray that are different from each other timewise and acquired by an ultrasonic probe; an elastic image data creation part which creates data on an elastic image in accordance with the distortion calculated by the distortion calculation part; a movement detection part which detects the movement of the biological tissue in a B-mode image BI; an angle calculation part which calculates an angle between the sound ray direction of the ultrasonic wave transmitted/received by the ultrasonic probe and the movement direction of the biological tissue detected by the movement detection part; and an image display processing part which displays an indicator In indicating the angle.SELECTED DRAWING: Figure 5
