Cone beam collimation for single photon emission computed tomography (SPECT) offers increased sensitivity for brain scanning through more complete use of the detector area. Parallel hole and fan beam geometries for brain imaging can exclude up to 50% of the detector surface. Attention is given here to converging or cone beam geometries. Using Monte Carlo simulation techniques, it is found that these geometries yield an increase in sensitivity of between 1.4 and 3 times. A fully three-dimensional inverse Monte Carlo (IMOC) reconstruction algorithm is developed for cone beam acquisition which includes compensation for attenuation
