Abstract

Calculation of physically-realistic radiation dose distributions for Boron Neutron Capture Therapy (BNCT) is a complex, three-dimensional problem. The Monte Carlo stochastic simulation technique has traditionally been the primary method for performing such calculations. A three-dimensional deterministic approach to the problem would offer some complementary advantages. Recently-completed work at the Idaho National Engineering Laboratory (INEL) has established that the three-dimensional discrete-ordinates (Sn) formulation offers such an approach. The method has been validated in detail against measurements taken in a canine-head phantom irradiated in the epithermal-neutron beam at the Brookhaven Medical Research Reactor (BMRR) located at Brookhaven National Laboratory (BNL) in Upton, NY. In addition, three-dimensional deterministic calculations of all relevant BNCT dose components have been completed for the three-dimensional phantom in the proposed INEL Power Burst Facility (PBF) epithermal-neutron beam.
