%X We present a new approach for creating polar maps of three-dimensional cardiac perfusion images. A polar map is a two-dimensional plot of the reconstructed volume from the SPECT study, which provides concise information on myocardial perfusion in a single easily interpretable image. Unlike the traditional approaches, our algorithm is automatic. It relies on image registration techniques to align the patient exam to a previously computed model, avoiding the need of manual intervention by a specialist. Preliminary analysis made by a specialist in nuclear medicine indicates that this new approach is comparable to the gold standard algorithm.
