Calculation of Absorbed Dose Distributions Using Removal- Diffusion Theory for BNCT Treatment Planning
Successful implementation of Boron Neutron Capture Therapy (BNCT), requires a knowledge of the radiation dose distributions in the tissue being treated. In order to plan a BNCT treatment, a treatment planning system is necessary, which is accurate, as well as, fast enough to calculate dose distributions in minutes. Most BNCT treatment planning has focused on Monte Carlo1,2 or Discrete Ordinates3 techniques. Removal-diffusion theory may provide an alternative calculation technique that may be both accurate enough and fast enough for BNCT treatment planning. This work investigates the use of removal-diffusion theory for BNCT to calculate neutron flux distributions and, subsequently, neutron absorbed dose distributions, within a patient’s head.
