The Inverse Monte Carlo (IMOC) reconstruction algorithm achieved compensation for two degrading collimator effects in SPECT imaging: position dependence and radial/tangential asymmetry in reconstructed resolution. With filtered backprojection using a ramp filter, Full Width at Half Maximum (radial and tangential respectivly) for a line source on axis with a high sensitivity collimator were 19.3mm and l6.4mm. At 12cm off axis, FWHM were 14.8mm and 8.2mm respectivly. With IMOC after 35 iterations, FWHM on axis were 8.4mm and 7.7mm while off axis FWHM were 6.0mm and 7.4mm respectivly. Thus, for the simple imaging task of line sources with no background activity using simulated projection data, IMOC provides compensation for the collimator effects in addition to providing higher resolution. © 1988 IEEE
