Abstract

Previous Single Photon Emission Computed Tomography (SPECT) myocardial perfusion imaging (MPI) research has explored the utility of numerical observers. One previous study proposed that the model of holistic visual search of a myocardial perfusion image by an expert human observer might improve the development of a SPECT MPI numerical observer. Further examination of numerical processing techniques that seem to be analogous to initial stage of human holistic image search has helped to further refine the numerical observer. The current numerical observer considers some fundamental issues in the refinement of the numerical observer: the need for background estimation, the determination of blobs and the 'search-like' selection of a few blobs for subsequent decision analysis.
