An imaging system using LaBr₃(Ce) detectors for online dosimetry for boron neutron capture therapy (BNCT) was studied. Various image reconstruction methods and conditions were tested in Monte Carlo simulation study. In addition, to see the feasibility, neutron beam experiments were carried out and gamma-rays from a phantom were detected with a LaBr₃(Ce) detector. Results of the simulation and experiments will be given in the presentation.
