摘要： A method of validating a compensator for use in a radiation therapy machine to treat a cancer patient involves determining a radiation treatment plan based on a compensator description file that includes data representative of an actual machined surface of the compensator. The plan includes operating parameters of the radiation therapy machine, and this plan is compared against actual radiation measurements taken during a non-patient test of the radiation therapy machine with the compensator mounted to the machine. If the comparison results in a match, the compensator is validated for use in the radiation therapy machine to treat the cancer patient.

摘要： A compensator is used with a radiation therapy machine to treat a cancer patient. A three-dimensional surface of the compensator is defined by obtaining a radiation dose requirement created by a treatment planning system associated with the radiation therapy machine and determining a plurality of grid elements based on that radiation dose requirement. At least one of a plurality of points on each of the plurality of grid elements is connected with at least one of the plurality of points on another one of the plurality of grid elements to form a representation of the three-dimensional compensator.
