Abstract
The 4DM-PET experiment aims to develop an innovative detector module for PET applications. The detector is based on a 20 × 20 × 10mm3 LYSO monolithic scintillator crystal coupled on the large opposite surfaces to 4 × 4 Silicon Photomultiplier pixel matrices of 5mm pitch. The Detector is connected to a custom designed Front-End ASICs managed by an FPGA-based read-out system. This configuration allows measuring the Depth of Interaction of gamma photons interacting in the crystal volume. To test the spatial resolution capabilities of this module the detector has been scanned with a pencil beam produced by collimated radioactive sources along the three dimensions of the crystal block. The results of the prototype characterization in terms of spatial resolution in the x-y plane and the Depth Of Interaction resolution are presented here.
