Fully-3D Image reconstruction of a Derenzo phantom scanned on the mini-EXPLORER-II without and with our resolution model. (a) Single-ray tracing projector w/o PSF modeling; (b) Pre-calculated system matrix w/multiple-ray tracing projector PSF modeling. The 1.6 mm hot rods can be resolved using our accurate system matrix modeling with the 2.85x2.85x18.1 mm3 crystal
