Characterization of a Compton camera based on the TOFPET2 ASIC

The use of Compton cameras for medical imaging and its interest as a hadron therapy treatment monitoring has increased in the last decade with development silicon photomultipliers. MACACOp is camera prototype designed assembled at IRIS group IFIC-Valencia. This based on monolithic Lanthanum (III) Bromide crystals photomultipliers, employs novel TOFPET2 ASIC readout electronics. system emerged an alternative to MACACO II prototype, aim improving limited time resolution. To test performance setup, was characterized, both laboratory in-beam. A resolution 1.5 ns obtained after corrections, which improves greatly II. Moreover, results high photon energies demonstrate ability obtain 1 mm displacements reconstructed spots. reinforce potential device therapy.
