RADIATION DOSE PREDICTING DEVICE, RADIATION DOSE PREDICTING METHOD, AND RADIATION DOSE PREDICTING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a radiation dose predicting device that can simulate with the maximum possible fidelity a three-dimensionally shaped model to be evaluated and figure out the result of calculation without taking an enormous length of time even where radiation sources are extensively distributed.SOLUTION: A radiation dose predicting device is equipped with a CG processor 13 that sets on the shape surface of a three-dimensionally shaped model radiation source information indicating the intensities of radiation sources, a first information setter 14 that sets multiple meshes by partitioning the shape surface of the three-dimensionally shaped model in a mesh pattern, sets multiple cells for each mesh, and sets for each cell a radiation source of a radiation intensity matching radiation source information, a second information setter 14 that sets calculation points in prescribed positions, and a radiation dose calculator 16 that calculates the radiation dose at the calculation point from the radiation source set in each cell.SELECTED DRAWING: Figure 2
