Table 4 Summary of depth of interaction reconstruction capability of the detector using the combination of the two investigated parameters, with both calibration methods: using the natural radioactivity of the lutetium and with the lateral scan

From: Depth of interaction determination in monolithic scintillator with double side SiPM readout
