Abstract

SPECT is one of the nuclear medicine imaging techniques and widely used in the clinical applications. Different from CT, SPECT achieved the functional image of the organ of interest, and the diseases can be found much earlier. Conebeam SPECT reconstruction can improve the photon density and spatial resolution of the reconstructed image, but it is time consuming. In clinic, doctors usually just care about the region of interest (ROI), such as heart, not whole body. Local reconstruction can reduce the reconstruction time. In this paper, based on Novikov's analytical SPECT reconstruction algorithm, we built a framework for local cone-beam SPECT reconstruction with non-uniform attenuation. The simulation results show our reconstruction framework is feasible
