N2 - This study investigates the potential of improving spatial resolution in SPECT imaging using a combination of LaBr3:Ce detectors and 3D-OSEM image reconstruction algorithms. Potential spatial resolution improvement was assessed intrinsically and extrinsically using GATE Monte Carlo simulation. Significantly improved MTF of LaBr3:Ce detectors suggests better resolution performance at all spatial frequencies. In comparison to conventional Nal(Tl) scintillators, a combination of the LaBr3:Ce crystal and 3D-OSEM incorporating resolution recovery could significantly improve the extrinsic spatial resolution of SPECT images.
