The purpose of OMEGA is twofold. First it is designed to allow easy, fast and efficient reconstruction of any PET data, including simulated GATE data. Secondly, it is intended for easy algorithmic development as it allows easy matrix-free implementation of the forward (A * x) and backward (A' * y) projections.
