Optimization of an intensity modulated field

摘要

The method for controlling radiation delivery involves defining a field on the object for irradiation. The field is divided into multiple section, each section having defined parameters. Each of the sections is treated individually with radiation. The treatment involves defining an opening between the radiation source and the object. The opening is place over one of the section and is capable of delimiting the radiation beam to the defined parameters of the section. radiation beam is generated with a lossless beam path from a radiation source to the object. The treatment is repeated until each section has been irradiated.
