Calculation of radiation therapy dose using all particle Monte Carlo transport
Abstract
The actual radiation dose absorbed in the body is calculated using threedimensional Monte Carlo transport. Neutrons, protons, deuterons, tritons, helium3, alpha particles, photons, electrons, and positrons are transported in a completely coupled manner, using this Monte Carlo AllParticle Method (MCAPM). The major elements of the invention include: computer hardware, user description of the patient, description of the radiation source, physical databases, Monte Carlo transport, and output of dose distributions. This facilitated the estimation of dose distributions on a Cartesian grid for neutrons, photons, electrons, positrons, and heavy chargedparticles incident on any biological target, with resolutions ranging from microns to centimeters. Calculations can be extended to estimate dose distributions on generalgeometry (nonCartesian) grids for biological and/or nonbiological media.
