Paper Abstract

We have developed a new algorithm for determining the cross- section range of the heart from a sequence of SPECT projection images. The new algorithm provides accurate estimation of the heart range for a fully automatic myocardial perfusion SPECT processing system. The limits of the heart range are used for reconstructing transverse images for the subsequent analysis. The basis of the approach is the 1D pseudo motion analysis which has three major components, spatial feature to position mapping, knowledge-driven analysis of heart region, and heart range determination. The main advantage of the algorithm is that the processing is fully automatic regarding no user intervention and is less sensitive to the image intensity distribution comparing to other existing methods.
