Abstract:
1. A medical kinematic analysis apparatus, including a processor, to analyze a cardiac motion from time series image data obtained by capturing a heart, comprising: a tracking point coordinate acquiring unit configured to generate coordinate time series data indicating a coordinate of a tracking point on a heart from time series image data obtained by capturing the heart; an image data storing unit that stores the time series image data; a motion information acquiring unit configured to generate time series motion information of the tracking point from the coordinate time series data; a contour extraction unit configured to extract a cardiac contour of the heart from the time series image data; a direction acquiring unit configured to acquire a first cardiac motion direction in a normal direction with respect to the cardiac contour at a point on the cardiac contour nearest to the tracking point and a second cardiac motion direction in a tangential direction with respect to the cardiac contour at the point on the cardiac contour nearest to the tracking point; a first motion component computation unit configured to compute a first motion component of the first cardiac motion direction from the time series motion information; and a second motion component computation unit configured to compute a second motion component of the second cardiac motion direction from the time series motion information.
