Patent ID: 8173968

Claim:
A radiation dosimetry quality assurance system configured to measure an actual radiation dose delivered by a radiation delivery system during a planned medical process, the radiation dosimetry quality assurance system comprising: a three-dimensional (3D) phantom extending from a first end to a second end along a longitudinal axis to form an exterior surface and an interior volume; a passage formed to extend into the interior volume of the 3D phantom to removeably receive a detector array therein; an angular-compensation system coupled to the exterior surface of the 3D phantom and having a physical contour extending from the exterior surface of the 3D phantom and configured to control an angular dependence of the detector array during measurement of the actual radiation dose delivered by the radiation delivery system during the planned medical process; and a detector-angle adjustment system configured to allow selection of a relative position of the detector array with respect to a radiation source of the radiation delivery system during measurement of the actual radiation dose delivered by the radiation delivery system during the planned medical process.
