Abstract
A technique for constructing a 3D human heart model is proposed for study of anatomy of the heart as well as the dynamic changes in the shape of left and right ventricles throughout the cardiac cycle. The model consists of 3D surfaces of epi- and endo-cardium of the heart which are reconstructed from serial ultrafast CT cross-sectional images. For each cross section, the regions of epi-and endo-cardium are first identified by using an adaptive segmentation algorithm. The boundaries of these regions are then extracted. With these boundaries, additional cross sections are generated by means of an elastic interpolation algorithm. The set of interpolated cross sections are then employed to form a cardiac surface which is subsequently smoothed using parametric surface schemes.
