Overview of Geant4 Application In Medical Physics

2004

We present a series of achievements associated with Geant4-based applications in medical physics and, in particular, in radiotherapy (external beams and brachytherapy), protontherapy, PEM, PET, MRT, metabolic therapy, IORT; projects in microdosimetry and radiobiology are beginning. The Geant4 CT-interface allows to reproduce realistically the patient anatomy, the integration to the GRID allows to run the applications sharing distributed computing resources. The Geant4 Medical Physics Group has born from the collaboration of Geant4 with several research and medical physics institutes in Europe.

Medical Applications of the Geant4 Toolkit

2001

A powerful and suitable tool for attacking the problem of the production and transport of different beams in biological matter is offered by the Geant4 Simulation Toolkit. Var- ious activities in progress in the domain of medical applications are presented: studies on calibration of brachytherapy sources and thermoluminescent dosimeters, studies of a complete 3-D inline dosimeter, development of general tools

G4DARI: Geant4/GATE based Monte Carlo simulation interface for dosimetry calculation in radiotherapy

Computerized medical imaging and graphics : the official journal of the Computerized Medical Imaging Society, 2018

Monte Carlo (MC) simulation is widely recognized as an important technique to study the physics of particle interactions in nuclear medicine and radiation therapy. There are different codes dedicated to dosimetry applications and widely used today in research or in clinical application, such as MCNP, EGSnrc and Geant4. However, such codes made the physics easier but the programming remains a tedious task even for physicists familiar with computer programming. In this paper we report the development of a new interface GEANT4 Dose And Radiation Interactions (G4DARI) based on GEANT4 for absorbed dose calculation and for particle tracking in humans, small animals and complex phantoms. The calculation of the absorbed dose is performed based on 3D CT human or animal images in DICOM format, from images of phantoms or from solid volumes which can be made from any pure or composite material to be specified by its molecular formula. G4DARI offers menus to the user and tabs to be filled with v...

MedLinac2: a GEANT4 based software package for radiotherapy

Annali dell'Istituto superiore di sanità, 2010

Dose distribution evaluation in oncological radiotherapy treatments is an outstanding problem that requires sophisticated computing technologies to optimize the clinical results (i.e. increase the dose to the tumour and reduce the dose to the healthy tissues). Nowdays, dose calculation algorithms based on the Monte Carlo method are generally regarded as the most accurate tools for radiotherapy. The flexibility of the GEANT4 (GEometry ANd Tracking) Monte Carlo particle transport simulation code allows a wide range of applications, from high-energy to medical physics. In order to disseminate and encourage the use of Monte Carlo method in oncological radiotherapy, a software package based on the GEANT4 Monte Carlo toolkit has been developed. The developed package (MedLinac2) allows to simulate in an adequate flexible way a linear accelerator for radiotherapy and to evaluate the dose distributions.

GEANT4 Simulation of an Accelerator Head for Intensity Modulated Radiotherapy

2005

We present a Geant4-based application for the simulation of the absorbed dose distribution given by a medical linac used for intensity modulated radiation therapy (IMRT). The linac geometry is accurately described in Monte Carlo code using the accelerator's manifacturer's specifications. The flexible design of this object-oriented system allows for an easy configuration of the geometry of the treatment head for
