摘要
What is described is a method for determining the volume of epicardial fat of a heart, comprising: - acquiring a plurality of volumetric image data representing the heart; - morphologically characterizing a volume of interest represented by the volumetric image data, including identifying a predetermined number of reference contours (P i ) of the heart; - estimating the epicardial surface, ˆ‘, according to a three-dimensional series expansion of vector spherical harmonic functions based on the reference contours (P i ); and - determining the volume of epicardial fat based on the voxels which are located inside the estimated epicardial surface, ˆ‘, and which have a grey level within a predetermined range, characteristic of fatty tissue.
