Description

MLEM methods are commonly used in PET and SPECT reconstruction. The paper presents a parallel implementation of MLEM using an OpenCL programming language. Evaluation of the algorithms is performed using simulated sinograms and real PET/SPECT data. Comparison with the CPU-based reference FBP and MLEM algorithms is performed
