Abstract:
A system to provide enhanced computational efficiency in a simulation of particle transport through a medium, program product, and related methods are provided. The system can include a simulation data administrator server having access to an interaction database including records related to parameters describing interactions of particles in an absorbing medium to provide particle interaction parameters, and a simulated dose calculation computer in communication with the simulation data administrator server through a communications network. The system can also included simulated dose calculation program product stored in memory of the simulated dose calculation computer and including instructions that when executed by a processor causes the processor to perform for each of a plurality of particles deliverable from a particle source the operations of providing parameters for a medium to perform a Monte Carlo simulation to develop a map of simulated absorbed dose in the medium, and artificially adjusting simulation particle fluxes to achieve a substantially constant variance throughout a depth of the medium.
