Abstract
The Voxel Imaging PET (VIP) Pathfinder project presents a new approach for the design of nuclear medicine imaging diagnostic devices by using highly segmented pixel CdTe sensors. State-of-the-art PET devices are made from scintillator crystals which have an energy resolution of about 10 %. Because of their limited energy resolution, the scatter fraction is relatively large. Their limited spatial resolution will introduce a parallax error and deficiency in the depth of interaction (DOI) determination (> 5 mm FWHM) and therefore a wrong line of response (LOR). In this study, we present a design for a breast dedicated PET based on CdTe detectors which have an energy resolution of about 1 % and can be easily segmented into small voxels for optimal spatial resolution to provide a solution for these setbacks. This simulation study will assess the advantages of this design for breast imaging purposes.
