Abstract

Radiation therapy is a technique for delivering sufficiently high doses to target cells while keeping the dose to neighboring normal tissues as low as possible. As an advanced radiation therapy method, proton therapy has a more ideal dose distribution than either electron or photon therapy due to the Bragg peak. Recently, an enhanced proton therapy based on the proton-boron ($^{11}$B) fusion reaction was proposed. For this method, alpha emitters from proton-boron fusion reactions are utilized to improve the dose deposition in the target. A few studies have confirmed this method by using the Monte Carlo N-Particle (MCNP) code. In our study, a mathematical method and the GEometry ANd Tracking (GEANT4) toolkit are combined to evaluate and analyze the dose distribution of the proton-boron ($^{11}$B) fusion-enhanced proton therapy (PBFEPT) method. Calculations of both the emitters of proton-boron ($^{11}$B) fusion reactions based on related cross-sections and the dose distribution of alpha emitters by using Geant4 toolkit, PBFEPT is found relatively to enhance the dose deposition in the target volume. This results agrees with those of previous studies.
