Evaluation of the Feasibility and Quantitative Accuracy of a Generalized Scatter 2D PET Reconstruction Method
Figure 5
(a) The image created by reconstructing 106 true coincidences using an LOR-MLEM with 36 iterations. (b) The image reconstructed using 106 scattered coincidences and an LOR-MLEM approach which assumes that these photons are true coincidences. (c) It uses the same scattered coincidences dataset as in (b) but reconstructs them using a GS-MLEM approach with 62 iterations. The second row plots the profiles through the above images in the horizontal and vertical direction passing through the center of the images, respectively.
