The use of Monte Carlo calculation is essential in radiation therapy.
Monte Carlo simulation is widely used for verifying the dose for nozzle
design, quality assurance, and the treatment planning system. GEANT4
simulation toolkit provides many powerful functions suitable for the dose
calculation in radiation therapy. In radiation therapy, both a simple
homogeneous water phantom and a complex volume extracted from CT data are
used for the dose calculation. Therefore, universal access to the particle
information regardless to the complexity of the geometries is desirable.
We extended functionalities of GEANT4 to allow two independent geometries
in one simulation application simultaneously, where one geometry
represents real materials and the other represents an artificial geometry
for a tally. In this report, we describe the parallel tally geometry in
GEANT4 for medical dose calculations. We also report the validation
results of this new capability.
