49. G4_Med, a Geant4 benchmarking tool for medical physics applications

Miguel Antonio Cortes Giraldo (Depto. de Fis. Atom., Mole. y Nucl.-Universidad de Sevilla)

Medical applications

Oral

Originating from high-energy and nuclear-physics domains, Geant4 is being adopted with increasing interest in the medical physics community, where it continues to gain significant momentum. Of particular interest to the medical physicists is its completeness, with a physics engine that covers the hadronic and nuclear interactions, of particular interest for novel ideas and techniques in the...

Medical applications

Oral

Intensity modulated proton therapy (IMPT) is an advanced form of radiation therapy in which the trajectory and energy of a focused beam of protons is precisely controlled so as to irradiate a tumor spot-by-spot and layer-by-layer with proton beamlets [1,2]. While the radiobiological effects of IMPT depend primarily on the physical dose distribution, studies have shown that linear energy...

25. Geant4 simulation of the ELIMED/ELIMAIA beamline, an open Users beamline for irradiation with laser-driven ion beams

Medical applications

Oral

The main direction proposed by the community of experts in the field of laser-driven ion acceleration is to improve particle beam features (maximum energy, charge, emittance, divergence, monochromaticity, shot-to-shot stability) in order to demonstrate reliable and compact approaches to be used for multidisciplinary applications, thus, in principle, reducing the overall cost of a laser-based...

47. Covering the upper clinical energy range of Geant4-DNA for proton transport in liquid water

Antonio Damián Domínguez Muñoz (Universidad de Sevilla)

24/04/2019, 17:20

Medical applications

Oral

Proton beams used in radiotherapy treatments can reach energies up to 250 MeV for deep-seated tumours. However, the existing cross section models included in Geant4-DNA [1,2] cover up to 100 MeV only. The goal of this work is to extend the current applicability range of Geant4-DNA for proton transport in liquid water up to, at least, 250 MeV.
Due to the energy range considered, the...

24. Assessment of specific absorbed fractions for HDRK-man phantom using Geant 4 code

maroua bhar

Medical applications

Oral

The main purpose of this paper is to present an overall study of the specific absorbed fractions (SAFs) of photon and electron sources to assess the internal doses after incorporation of radionuclides into the human body. SAF values for self and cross-absorption were calculated for a uniform distribution of mono energetic photon and electron emitters with energies ranging from 15 keV to 3...

27. MIRTO: A microdosimetric study and RBE measurement with 62 MeV clinical proton beam

Dr Giada Petringa (INFN-LNS)

Medical applications

Oral

CATANA (Centro di AdroTerapia ed Applicazioni Nucleari Avanzate) was the first Italian protontherapy facility dedicated to the treatment of ocular neoplastic pathologies. Since 2002, it is in operation at the LNS Laboratories of the Italian Institute for Nuclear Physics (INFN-LNS), to date 400 patients have been successfully treated. Nowadays, a slightly increased biological effectiveness...
