Quantitative analysis of prompt gamma ray imaging during proton boron fusion therapy according to boron concentration
The purpose of this study is to evaluate the prompt gamma ray imaging technique according to the clinical boron concentration range during proton boron fusion therapy (PBFT). To acquire a prompt gamma ray image from 32 projections, we simulated four head single photon emission computed tomography and a proton beam nozzle using a Monte Carlo simulation. We used modified ordered subset expectatio...
متن کاملA First step toward for Prompt Gamma Ray imaging technique during Antiproton Therapy using Boron particle
In this study, we propose a tumor monitoring technique using prompt gamma rays emitted from the reaction between an antiproton and a boron particle, and verify the improvement of the therapeutic effectiveness of the antiproton boron fusion therapy compared with proton and antiproton beam without boron. The tumor monitoring system during the antiproton therapy was simulated using the Monte Carlo...
متن کاملComparison between proton boron fusion therapy (PBFT) and boron neutron capture therapy (BNCT): a Monte Carlo study
The aim of this study is to compare between proton boron fusion therapy (PBFT) and boron neutron capture therapy (BNCT) and to analyze dose escalation using a Monte Carlo simulation. We simulated a proton beam passing through the water with a boron uptake region (BUR) in MCNPX. To estimate the interaction between neutrons/protons and borons by the alpha particle, the simulation yielded with a v...
متن کاملProton Linacs for Boron Neutron Capture Therapy
Recent advances in the ability to deliver boron-containing drugs to brain tumors have generated interest in -4 MeV liiacs as sources of epithemtal neutrons for radiation therapy. In addition, fast neutron therapy facilities have been studying methods to moderate their beams to take advantage of the high cross section for epithennal neutrons on boron-10. This paper describes the technical issues...
متن کاملEvaluation of the effective dose during PBFT for brain cancer: A Monte Carlo Study
Introduction: Recently, an approach exploiting the proton therapy biological enhancement by using Boron atoms injected inside a tumor, has been proposed. Three alpha particles with an average energy around 4MeV are emitted from the point of reaction between a proton and boron. In addition, the 719 keV prompt gamma emitted by the proton Boron fusion reactions can be used for on-...
