GEANT4 tuning for pCT development
(2011-09-09)
Proton beams in medical applications deal with relatively thick targets like the human head or trunk. Thus, the fidelity of proton computed tomography (pCT) simulations as a tool for proton therapy planning depends in the ...
Proton transport in water and DNA components: A Geant4 Monte Carlo simulation
(Elsevier, 2013-07)
Accurate modeling of DNA damages resulting from ionizing radiation remains a challenge of today's radiobiology research. An original set of physics processes has been recently developed for modeling the detailed transport ...
Performance of GEANT4 in dosimetry applications: Calculation of X-ray spectra and kerma-to-dose equivalent conversion coefficients
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
In order to validate the Geant4 toolkit for dosimetry applications, simulations were performed to calculate conversion coefficients h(10, alpha) from air kerma free-in-air to personal dose equivalent Hp(10, a). The simulations ...

On the design of experiments based on plastic scintillators using GEANT4 simulations
(Pergamon-Elsevier Science Ltd, 2018-12)
Plastic scintillators are widely used as particle detectors in many fields, mainly, medicine, particle physics and astrophysics. Traditionally, they are coupled to a photo-multiplier (PMT) but now silicon photo-multipliers ...
Geant4 simulation of the solar neutron telescope at Sierra Negra, Mexico
(Elsevier Science, 2010-02)
The solar neutron telescope (SNT) at Sierra Negra (19.0°N, 97.3°W and 4580 m.a.s.l) is part of a worldwide network of similar detectors (Valdés-Galicia et al., (2004) [1]). This SNT has an area of 4 m2; it is composed by ...
Comparison of the GEANT4 releases 8.2 and 9.2 in terms of a pCT reduced calibration curve
(2010-12-01)
The GEANT4 simulations are essential for the development of medical tomography with proton beams pCT. In the case of thin absorbers the latest releases of GEANT4 generate very similar final spectra which agree well with ...
