Abstract

One of the main challenges for building high resolution PET scanners with sub-millimeter resolution is to compensate for the parallax error induced by the height of the detector elements. During the last years several approaches to extract depth of interaction information for pixilated scintillation detectors were evaluated. We investigate the feasibility of a two layer PET detector with single sided readout using digital SiPM (dSiPM) arrays whereby the depth information is encoded in the width of the light distribution.
