Study of 4 inorganic scintillating crystals for an operative gamma probe in radioguided surgery

Abstract : In case of lymphatic cancers, the sentinel lymph node technique is performed using a gamma probe for intraoperative radioguided surgery. The inorganic scintillating crystal gamma probe developed at IPHC was equipped with 4 fast decay time inorganic scintillators: YAP, LYSO, LaCl3 and LaBr3. Energy resolutions are compared experimentally with single photon radioisotopes for small crystal cylinders (4 mm diameter, 12 mm length). The 6.1% measured energy resolution at 511 keV demonstrates the great advantage to use the high photon yield LaBr3 crystal for detection of γ-ray coming from positron annihilation using β+ radiomarked molecules
