摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic signal analyzer etc. which can make information about movement or deformation of a 2-dimensional (or 3-dimensional) tissue into video precisely by simple and speedy data processing by solving problems of a conventional method.;SOLUTION: Based on 2-dimensional or 3-dimensional tracking utilizing B-mode animation data, a first movement vector defined by the movement quantity and the movement direction of the tissue is obtained concerning a plurality of points of the tissue. Based on tissue Doppler animation data, the movement velocity of the plurality of points of the tissue along an ultrasonic scanning direction is obtained. Based on the first movement vector and the movement velocity, a second movement vector concerning the plurality of points of the tissue is obtained. Based of the second movement vector, an image about the movement of the tissue is generated. These are performed by the ultrasonic signal analyzer characteristically.;COPYRIGHT: (C)2007,JPO&INPIT
