Abstract
The present invention is a dynamic radiation scanning system for detecting radiation dosimetry of a beam emitted along an axis from a radiotherapy treatment machine and a method for its use. The system contains a dosimetry probe to sense photons and electrons, a dynamic phantom body formed from a material having a density approximating that of the human body, a gantry mounting assembly rigidly attached to the radiotherapy machine for positioning of the phantom body, and a lead screw assembly rigidly affixed to the gantry for providing coplanar movement of the dynamic phantom within a plane perpendicular to the axis of radiation emission. Movement of the dynamic phantom through a series of locations is carried out at varying depths and angles so as to provide sufficient data to determine variations in beam uniformity, thereby providing for simple and reliable testing and calibration of the machine.
