A Monte Carlo study of SPECT in boron neutron capture therapy for a heterogeneous human phantom

Background: Boron neutron capture therapy (BNCT) is a binary radiotherapy combining biochemical targeting with neutron irradiation. However, monitoring the boron distribution is a fundamental problem in BNCT. Prompt gamma rays emitted by boron capture reaction can be used to address the issue. Materials and Methods: The general-purpose Monte Carlo toolkits Geant4 and MCNP were used for the simu...

Monte Carlo Simulations for Non-destructive Elemental Analysis of Large Samples by Neutron Activation Analysis

Neutron Activation Analysis (NAA) is an established nuclear analytical technique with applications in a broad range of scientific and technological fields. Typically, conventional NAA involves analysis of small material portions of 10 to 100 g in mass. However, analysis of samples of a larger mass implies a number of additional advantages such as (a) analysis of objects too precious to remove ...

Design 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...

Monte Carlo-based optimization of a gamma probe system for sentinel lymph node mapping

Introduction: Sentinel lymph node biopsy (SLNB) is a standard surgical technique to identify sentinel lymph node (SLN) for the staging of early breast cancer. Nowadays, two methods are used for the identification of SLN: blue dye method aiding visually and radioactive dye using gamma detector. A wide range of gamma probe systems with different design and performance are used in...
