Outline of Final Research Achievements |
It was subjected to analysis of the movement of the left ventricular wall of the four-dimensional cardiac CT image including a motion due to heart rate. We have studied (1) parametric techniques of expressing wall motion as a change of shape parameters, (2) non-parametric techniques for finding the correspondence between the points on the left ventricular wall based on the periodicity by the heartbeat, and (3) development of software tools to visualize changes and trajectory of the wall thickness. As a result of analyzing the change of shape parameters, the possibility of distinction between normal and abnormal findings was suggested.
