		<abstract>In this paper we present a new approach for quantitative analysis of myocardial perfusion SPECT studies and assessment of myocardium defect regions. Myocardial perfusion SPECT is widely used in the evaluation of post-infarction patients, in order to foretell the patients future conditions. Our approach is based on the use of polar maps, a two-dimensional plot of the reconstructed volume from the SPECT study. Using an automatic technique for polar map creation, based on image registration techniques, we were able to generate six different polar maps, allowing medical visual interpretation and analysis of myocardium defect regions.</abstract>
