DEFINING THE VOLUMETRIC DIMENSIONS AND SURFACE OF A COMPENSATOR

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.
