Abstract
Depth-of-Interaction (DOI) encoding is an important requirement in clinical as well as small animal Positron Emission Tomography (PET). At present, almost all commercial PET scanners do not have DOI encoding capability, and, as a result, these scanners exhibit parallax error, which degrades their spatial resolution for events that are further away from the central axis in the radial direction. This project will investigate a new detector design that promises to provide high resolution DOI encoding in a continuous manner with single-ended scintillator readout. The proposed scheme can be adapted to small animal as well as clinical PET scanners. Phase I will demonstrate the feasibility of the new detector configuration and will optimize the detector design. In Phase II, the concept will be implemented by building a PET system with DOI encoding. Commercial Applications and other Benefits as described by the awardee: The detector technology should be very promising for small animal as well as clinical PET applications. It also should be applicable to many other gamma-ray imaging systems for astronomy, non-destructive studies, and nuclear non-proliferation, which require depth-of-interaction information.
