Evaluation of the Feasibility and Quantitative Accuracy of a Generalized Scatter 2D PET Reconstruction Method

<table>The CRC curves for the #4 (cold) disk calculated when only trues are present and with 50% scatter fraction calculated using the conventional LOR-MLEM approach and with the GS-MLEM approach using different thresholds defined by the ratio of the intersection area between the TCA and image matrix to the total image matrix area. Points #1, #2, and #3 identify the evaluation points for reconstruction using GS-MLEM method, only trues, and the LOR-MLEM, respectively.</table>
