Region-Based Partial Volume Correction Techniques for PET Imaging: Sinogram Implementation and Robustness

Figure 3

Five VOIs plus background (a) were chosen from the Zubal brain phantom. These VOIs were assigned different relative uptake values to create an ideal PET image in MR-space (b). The ideal PET image was then downsampled, forward projected, filtered, and reconstructed to create a simulated PET image (c) for GTMo and sGTMo PVC methods.
