Abstract
Optimization of the Compton camera for measuring prompt gamma rays (0.478Â MeV) emitted during boron neutron capture therapy (BNCT) was performed with Geant4. The parameters of the Compton camera were determined as follows: 3Â cm thick - 10Â cm wide scatter detector (Silicon), 10Â cm thick - 10Â cm wide absorber detector (Germanium), and 1Â cm distance between the scatter and absorber detectors. For a typical brain tumor treatment, the overall detection efficiency of the optimized Compton camera was approximately 0.1425% using the Snyder's head phantom with a sphere tumor (4Â cm diameter and ~1Â cm depth).
