Evaluation of the Feasibility and Quantitative Accuracy of a Generalized Scatter 2D PET Reconstruction Method
Figure 10
(a) The image using true coincidences reconstructed using an LOR-MLEM reconstruction algorithm. (b) The image using the same true coincidences plus scattered coincidences that fall into the 350–511 keV energy window reconstructed using the conventional LOR-MLEM algorithm as a comparison. (c) The image using coincidences with a 50% scattering fraction reconstructed using the GS-MLEM algorithm. The second row shows the profiles of the above images along horizontal and vertical direction passing through the center of the images, respectively.
