The detailed procedure for each stage. a The HU thresholds were automatically calculated by the multi-Otsu algorithm. At the same time, the investigator draws the basic guidelines after image processing. b The myocardial wall extracted based on the morphological dilation and threshold overlap. And the final thickness was calculated by the Laplace equation and Euler methods. c The commutative property of the points P and P’ by orthogonal projection distances were not suitable in the cardiac CT
