Abstract

The measurement of left ventricular function will be greatly enhanced when the 3-D shape of the ventricle can be closely assessed from biplane angiocardiograms taken from two perpendicular X-ray camera sets. The ventricle shape at a given time can be reconstructed by dividing each of the two orthogonal projection images into corresponding slices, processing each pair of corresponding slices to form a binary cross-sectional image, and stacking up these parallel cross-sectional images. The authors recently proposed an approach to reconstruct each cross section by estimating an equal-divisor curve instead of estimating the boundary directly. Here they extend the notion of the equal-divisor curve of a 2-D object to that of the equal-divisor surface of a 3-D object and develop a method of direct 3-D reconstruction of the left ventricle instead of piling up the parallel reconstructed 2-D cross sections.
