METHODS AND SYSTEMS USING MODELING OF CRYSTALLINE MATERIALS FOR SPOT PLACEMENT FOR RADIATION THERAPY

摘要

A crystalline structure modeling methodology that is conventionally used to model crystalline matter down to the atomic level is instead used to determine spot placement for radiation treatment. The cross-sectional shape of a treatment target is specified 202; locations (peaks) in a density field inside the shape are determined using the crystalline structure model 204; locations of spots in the treatment target for spot scanning are determined 206, where the locations correspond to the locations (peaks) inside the shape determined using the crystalline structure model; and the locations of the spots are stored as candidates for potential inclusion in a radiation treatment plan 208.
