## Indications for use
MillComp is used to manufacture compensators that are designed for radiation therapy treatment beams. MillComp may be used with any system that can design compensators such that the thickness over the area of the beam is specified at some known source to compensator distance in a plane perpendicular to the central axis. The thickness on an evenly spaced grid may be specified on divergent rays or on rays perpendicular to the plane of the compensator which is perpendicular to the central ray. If on divergent rays, the milled surface may be specified as towards the x-ray source or as towards the patient.
