Abstract (in Japanese) (See Japanese page) 
(in English) We tried to analyze the change in shape of the left ventricle that was extracted from ECG-gated cardiac CT image using principal component analysis. ECG-gated cardiac CT images are 4-dimensional data, include heartbeat of one times separated by time phase. We applied the principal component analysis to left ventricle shapes in the CT images. We represented shape change by heartbeat of the normal and cardiac infarction cases using up to main components, which was determined based on the cumulative contribution rate by principal component analysis. We describe the result of the shape analysis.
