In this paper, an image-based and spatially variant resolution model (i.e. PSF model) was derived from reconstructions of a series of point sources, and used to recover the resolution loss in PET imaging. Since this PSF model was not only system dependent, but also reconstruction algorithm dependent, two reconstruction projectors were compared: one was the single-ray-tracing (1-ray) and another was...
We studied the impacts of CT dose reduction on PET quantitation with combination of currently available techniques by phantom and human studies on a Toshiba PET/CT prototype scanner with TOF capability. For the phantom studies, an anthropomorphic torso phantom and an IEC phantom were scanned using both diagnostic quality CT protocols and dose-reduced CT protocols. To achieve reduced-dose CT scans,...
