The performance of three camera-based detector configurations for single photon emission computed tomography (SPECT) have been compared for system sensitivity and spatial resolution in the reconstructed images. These configurations are the flat detector with parallel channel collimation, the flat detector with focused channel collimation, and the fan-curved detector with focused channel collimation. The analysis was done by simulation of the projection data collection process in the collimator-detector assembly and subsequent image reconstruction for each configuration. Generally the results indicate that both the system sensitivity and image spatial resolution can be simultaneously improved by using large-area detectors with focused collimators. Although the depth-dependence of collimator spatial resolution introduces point spread function (psf) shape anisotropy along the radius varying both in the radial and azimuthal directions, it does not significantly degrade reconstructed image quality
