TL;DR: This paper presents the most recent review of the Geant4-DNA extension, as available to Geant 4 users since June 2015 (release 10.2 Beta), and includes the description of new physical models for thedescription of electron elastic and inelastic interactions in liquid water, as well as new examples dedicated to the simulation of physicochemical and chemical stages of water radiolysis.
Journal ArticleDOI
Fully 3D Monte Carlo reconstruction in SPECT: a feasibility study.
TL;DR: The value of using accurate Monte Carlo simulations to determine the 3D projector used in a fully 3D Monte Carlo (F3DMC) reconstruction approach is investigated and it is suggested that F3D MC improves spatial resolution, relative and absolute quantitation and signal-to-noise ratio.
Journal ArticleDOI
Geant4 Monte Carlo simulation of absorbed dose and radiolysis yields enhancement from a gold nanoparticle under MeV proton irradiation

TL;DR: In this paper, an in-silico investigation based on the general purpose Monte Carlo simulation toolkit Geant4 is performed into energy deposition and radical species production around a spherical gold nanoparticle 50 nm in diameter via proton irradiation.
Journal ArticleDOI
Monte Carlo simulation of energy-deposit clustering for ions of the same LET in liquid water
Ziad Francis,Sebastien Incerti,Vladimir Ivanchenko,Christophe Champion,M. Karamitros,Mario A. Bernal,Z. El Bitar +6 more
TL;DR: A Monte Carlo study of energy depositions due to protons, alpha particles and carbon ions of the same linear-energy-transfer (LET) in liquid water using the Geant4-DNA toolkit and an adapted version of the DBSCAN clustering algorithm.
