Abstract:
1. A system for increasing efficiency in a simulation of particle transport through a medium, comprising: a communication network; an image gathering device accessible to the communication network to provide an at least two-dimensional image slice of a target volume and an adjacent structure volume in a patient; a radiation treatment planning computer in communication with the image gathering device and having memory, a processor coupled to the memory, and a radiation treatment planning program product stored in the memory adapted to produce an optimized radiation treatment plan for delivering radiation to the target volume; a radiation beam source to deliver radiation to the target according to the radiation treatment plan; a simulation data administrator server in communication with the communication network and having access to an interaction database including records related to parameters describing interactions of particles in an absorbing medium to provide particle interaction parameters; a simulated dose calculation computer in communication with the radiation treatment planning computer and the simulation data administrator server through the communication network and including memory and a plurality of processors coupled to the memory to calculate a simulated absorbed dose in the absorbing medium deliverable according to the radiation treatment plan; and a simulated dose calculation program product stored in the memory of the simulated dose calculation computer and including instructions that when executed by at least one of the plurality of processors causes the at least one of the plurality of processors to perform the operation of modeling the target volume and adjacent structure volume to define the absorbing medium and to perform for each of a plurality of particles deliverable from the beam source the following simulation operations:
