Abstract
The development of an endorectal PET Time Of Flight (TOF) probe prototype compatible with MRI, is going to be carried out within the INFN project TOPEM. Time resolution and depth of interaction (DOI) will allow to significantly improve the image quality, by rejecting those events coming from the surrounding tissues and correcting the parallax error. The activity described in this paper is focused on the characterization of the single pixel detector of the probe, consisting of a LYSO finger scintillator read out at both ends by means of a pair of Silicon Photomultipliers (SiPM). Energy, timing and DOI resolutions have been measured with a proper surface treatment and wrapping, finding very competitive results for DOI and timing. (C) 2012 Elsevier B.V.
