A visualization application on mobile devices for Geant4-based radiotherapy simulation

Geant4 has been widely used in medical physics applications. It takes charge of the important role in radiotherapy in order to precisely evaluate dose distributions in an irradiated patient or to optimize devices of a beam delivery system. Geant4 is a toolkit for the Monte Carlo simulation of the passage of particles through matter. We describe application software on mobile devices, which is a volume visualizer for the Geant4-based radiotherapy simulation. It is named as gMocren. To visualize volume data on mobile devices is challenging, because mobile devices that has only fewer resources than ones of a recent personal computer. However they provide a useful and friendly user interface. gMocren on mobile devices is useful to confirm anywhere a result of the simulation in a PC network.
