<P>PROBLEM TO BE SOLVED: To provide a three-dimensional ultrasonic diagnostic apparatus highly accurately diagnosing abnormal movement of an object tissue. <P>SOLUTION: An edge detector 34 executes a process to extract a surface of an inner wall of a left ventricle from a binarized image output from a binarization circuit 30. A telediastolic edge memory 38 stores an intracardial surface image at the end of ventricular diastole from among intracardial surface images for respective phases output from the edge detecting means 34. A displacement detecting section 50 detects the amount of displacement between the phases for each site of the intracardial surface from the intracardial surface image at the end of diastole which is output from the telediastolic edge memory 38, a current intracardial surface image which is output from the edge detecting means 34, and a center-of-mass coordinate of the intracardial section at the diastole which is stored in a telediastolic center-of-mass memory 44. A coloring processing section 56 applies a coloring process to each site of the surface of the current intracardial surface image based on the amount of displacement and outputs the result to an image synthesizer section 58. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
