Evaluation of Image Quality Improvements When Adding Patient Outline Constraints into a Generalized Scatter PET Reconstruction Algorithm
Figure 9
The CRC curves of no. 4 (cold) disk calculated using GS-MLEM with different phantom outline constraints. The CRC for 3 × 105 true coincidences and 6 × 105 coincidences with 50% scattered fraction using conventional LOR-MLEM were also reconstructed as a comparison.
