Epithermal Neutron Beam Generator Design for Bnct
BNCT is a radiotherapy modality based on the neutron capture and fission reactions that occur when boron-10 is irradiated by thermal neutrons. This reaction generates alpha and lithium that produce high density of ionizations in close to the reaction site. The concept provides high absorbed doses into the cancerous cells preserving the adjacent healthy tissues. Nowadays, the available neutron s...
متن کاملطراحی و بهینه‌سازی طیف نوترونی برای درمان تومورهای عمیق مغزی به روش BNCT با کاهش آسیب رسیده به پوست
Boron neutron capture therapy (BNCT) is an effective method for treatment of deep seated brain tumors. This method consists of two stages: injection of boron compound in the patient body, and then irradiation of the region tumors with the neutron beam. It allows for delivery of high linear energy transfer (LET) radiation (particles 4He and 7Li nuclei) to tumors at the cellular level whilst avoi...
متن کاملOptimum neutron energy simulation in treatment of head and neck cancer at different depths in the BNCT method
Introduction: Recently head and neck cancer has pay attention to many researchers. Its therapeutic methods include surgery, chemotherapy, radiotherapy and Boron neutron capture therapy (BNCT). BNCT is better than conventional radiotherapy because it targets the tumor cell. This method involves two steps of infusion of stable 10B and then neutron radiation with a suitable intens...
متن کاملOptimization study for BNCT facility based on a DT neutron generator
Background: A Boron Neutron Capture Therapy (BNCT) facility, based on a DT neutron generator, with the final goal to find out a potential, alternative, solution to existing BNCT treatment facilities which are based on nuclear reactors is examined. Materials and Methods: With the aim of the MCNP4B Monte Carlo code different beam-shaping assembly (BSA) configurations were considered. Lead was sel...
متن کاملNumerical optimisation of the fission-converter and the filter/moderator arrangement for the Boron Neutron Capture Therapy (BNCT)
Boron Neutron Capture Therapy (BNCT) [4, 5] is a form of a radiation therapy used for treatment of some kinds of cancer (mainly glioblastoma multiforme) which, due to their character, are hard to be extracted with surgical methods. The BNCT method involves the delivery of a capture compound − the B isotope is usually used – which preferentially concentrates in the cancer tissue, followed by the...
