Abstract

A novel technique for three-dimensional (3-D) mapping of left ventricular (LV) aneurysm is introduced, and utilized to map eight human hearts, studied in vivo by ultrafast tomography (cine-CT). The technique utilizes geometrical cardiograms (GCGs) to characterize the LV's 3-D geometry. The Karhunen-Loeve transform applied to a reference group of GCGs obtained from 10 healthy hearts can be reconstructed with a minimal mean square error (MSE) of approximation; the GCGs of abnormal hearts demonstrate a significantly larger MSE. 3-D maps of the LV indicating the suspected regions of aneurysm are obtained by studying the regional errors of approximation, and thresholding for a value that designates the limit for normal hearts. The maps are in good agreement with wall-thickness analysis.
