Fig. 4From: The future of hybrid imaging—part 2: PET/CT a Spatial resolution of PET deteriorates towards the edge of the FOV because of the increased depth-of-interaction effects (b). Resolution recovery (RC) is possible by measuring a standard point source throughout the FOV and deconvolving the image signal with the spatially variant point spread function. c As a result, images are less noisy and spatial resolution is made more uniform, yielding an overall improved image quality.
