abstract
We present a novel analysis method for image reconstruction in emission tomography. The method, named Reconstructed Image from Simulations Ensemble (RISE), utilizes statistical physics concepts and Monte Carlo techniques to extract the parameters of a physical model representing the imaged object from its planar projections. Its capabilities are demonstrated and evaluated by reconstructing tomographic images from sets of simulated SPECT projections. The RISE results compare favourably to those derived from the well - known Maximum Likelihood Expectation Maximization (MLEM) method, the Algebraic Reconstruction Technique (ART) and the Filtered Back Projection (FBP).
