Effect of the radiation field of view and angle in unconventional angiography on patient doses: a Monte Carlo simulation study using a voxelized phantom
Introduction: We aimed to investigate the effect of variation of beam angle and field of view (FOV) on organs’ and effective doses for patients undergoing interventional cardiology examinations by using Monte Carlo simulations and ICRP110 phantom. Materials and Methods: Simulations were done for energies obtained from experimental measurements on the left...
متن کاملA 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...
متن کاملThe Monte Carlo Assessment of Photon Organ Doses from 222Rn Progeny in Adult ORNL Phantom
Introduction The potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. Some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. While γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the p...
متن کاملEGSnrc Monte Carlo calculated dosimetry parameters for Ir and Yb brachytherapy sources
This study presents the results of EGSnrc Monte Carlo calculations of the dose distribution surrounding a high dose rate Yb brachytherapy source and 14 high dose rate and pulsed dose rate Ir brachytherapy sources. Energy-weighted spectra of emitted photons, a full set of TG-43 dosimetry parameters, along-away dose tables, and a description of the materials and geometry used for each source are ...
متن کاملComparison of MCNP4C, 4B and 4A Monte Carlo codes when calculating electron therapy depth doses
ABSTRACT Background: accurate methods of radiation therapy dose calculation. There are different Monte Carlo codesfor simulation of photons, electrons and the coupled transport of electrons and photons. MCNPis a general purpose Monte Carlo code that can be used for electron, photon and coupledphoton-electron transport.Monte Carlo simulation of radiation transport is considered to be one of the ...
