Review of Accelerator-based Boron Neutron Capture Therapy Machines
Accelerator-based BNCT (Boron Neutron Capture Therapy) facilities are being studied, developed and constructed at many laboratories and hospitals, especially in Japan. In order to provide sufficient neutron flux in the epi-thermal energy region (0.5 ~ 10 keV), an intense proton beam accelerated with a cyclotron, linear accelerator (linac) or DC accelerator up to 2.5 ~ 30 MeV is directed to lith...
متن کاملDesign and Simulation of Photoneutron Source by MCNPX Monte Carlo Code for Boron Neutron Capture Therapy
Introduction Electron linear accelerator (LINAC) can be used for neutron production in Boron Neutron Capture Therapy (BNCT). BNCT is an external radiotherapeutic method for the treatment of some cancers. In this study, Varian 2300 C/D LINAC was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for BNCT. Materials and Methods Photoneutron sources w...
متن کاملOptimization of an accelerator-based epithermal neutron source for neutron capture therapy.
A modeling investigation was performed to choose moderator material and size for creating optimal epithermal neutron beams for BNCT based on a proton accelerator and the (7)Li(p,n)(7)Be reaction as a neutrons source. An optimal configuration is suggested for the beam shaping assembly made from polytetrafluoroethylene and magnesium fluorine to be placed on high current IPPE proton accelerator KG...
متن کاملDesign of an accelerator-based neutron source for neutron capture therapy.
The boron neutron capture therapy is mainly suited in the treatment of some tumor kinds which revealed ineffective to the traditional radiotherapy. In order to take advantage of such a therapeutic modality in hospital environments, neutron beams of suitable energy and flux levels provided by compact size facilities are needed. The advantages and drawbacks of several neutron beams are here analy...
متن کاملNeutron Producing Target for Accelerator Based Neutron Capture Therapy*
Pilot innovative accelerator based neutron source for neutron capture therapy of cancer [1] is now on the threshold of its operation at the BINP, Russia. One of the main elements of the facility is lithium target producing neutrons via threshold Li(p,n)Be reaction at 25 kW proton beam with energies 1.915 MeV or 2.5 MeV. In the present report, choice of target is substantiated, the main problems...
