<P>PROBLEM TO BE SOLVED: To provide an ultrasonograph for diagnosing abnormal motion of an object tissue with further good accuracy. <P>SOLUTION: According to a binarized ultrasonic image, a ventricle center of gravity operation part 26 computes a ventricle center of gravity point, and a valve ring part center of gravity operation part 36 computes a valve ring part center of gravity point. A readout control part 40 sets a readout address so that in the respective frames, straight lines passing the ventricle center of gravity point and the valve ring part center of gravity point overlap each other. An echo data in a frame memory 18 is copied still as it is with an address of an original image in a frame buffer 46. A buffer control part 44 reads out echo data from the frame buffer 46 and outputs the same to a display image forming part 50 and a displacement hysteresis image forming part 48 according to a readout address calculated by a readout address generator 42. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
