Abstract A technique for constructing a three-dimensional (3-D) human heart model is proposed for study of anatomy of theheart and the coronary vessels as well as the dynamic changes in the shape of left and right ventricles throughout thecardiac cycle. The proposed model consists of the 3-D surfaces of epi- and endo-cardium of the heart with the coronarytree attached on the epicardium. The spatial 3-D geometry of coronary arteries is constructed from the stereoscopicradiographic images. The 3-D surfaces of epi- and endo-cardium of the heart are reconstructed from serial ultra fastCT cross-sectional images. For each cross section, the regions of epi- and endo-cardium are first identified by usingan adaptzve segmentation algorithm. The boundaries of these regions are then extracted. Using these boundaries,additional cross sections are generated by means of an elastic interpolation algorithm. The set of interpolated crosssections are then employed to form a cardiac surface which is subsequently smoothed using a spline-based surfaceinterpolation method.
