GPU GEant4-based Monte carlo Simulations

Introduction

GGEMS is an advanced Monte Carlo Simulations platform using GPU architecture targeting medical applications (imaging and particle therapy). This code is based on the well-validated Geant4 physics model and capable to be executed in both CPU and GPU (NVIDIA) device.

Features of GGEMS platform:

The aim is targeting these medical applications:

A first version of GGEMS will be released in last trimester 2017 including only CT imaging and external radiotherapy based on phasespace source. Version of GGEMS will be extended with new features and applications release after release.
