Method and apparatus for intensity modulated arc therapy sequencing and optimization

摘要

A treatment planner (102) generates fluence maps (140) indicative of a desired fluence distribution at various locations (304, 312) along a treatment arc (302). A converter (142) converts the fluence distributions (140) to treatment device settings (144). The settings (144) may include multiple segments. A segment distributor (146) distributes the settings to locations in the vicinity of their original positions.
