Abstract: In this paper, the authors/researchers will introduce the incremental optimisation transfer framework to estimate emission means in positron emission tomography. The proposed algorithms accelerate convergence speeds and ensure global convergence (to a stationary point) under mild regularity conditions without inconvenient relaxation parameters. In experiments using synthetic data and real phantom data, it was found that, for a fixed level of background noise, the proposed idea in this paper provides high-quality reconstructed images.

Keywords: positron emission tomography; PET; incremental optimisation transfer; IOT; penalised likelihood estimate; emission image reconstruction; reconstructed images.
