Paper Abstract

A new approach is presented for determining left ventricular (LV) shape in a sequence of gated blood pool single photon emission computed tomography data. The approach consists of the automatic extraction and fitting of an analytical ellipsoidal surface that well-approximates the shape of the LV. Data from all slices and geometric characteristics of the analytical surface are exploited to enable robust and (over- constrained) recovery of the LV shape parameters. Examination of 3D renderings of the surface coupled with computation of LV volume and motion parameters over the systolic cycle can allow qualitative and quantitative determination of LV function.
