Abstract: Patient motion during PET imaging acquisitions can result in distortions and artifacts that make accurate interpretation of the image sets difficult. In an attempt to develop a model-based approach, the feasibility of using Monte Carlo (MC) techniques for developing a probabilistic model for PET imaging is investigated. A two dimensional model and its formulation in the Radon space are presented in the scatter-free, scatter, and random noise situations. The reconstructed results using filtered back projection technique demonstrate the feasibility of the approach for clinical application.
