Patent ID: 8093549

Claim:
A radiation beam analyzer for detecting radiation dosimetry of a beam emitted along an axis from a radiotherapy treatment device comprising: a dynamic phantom body formed of a material having a density proximally that of a human body; a tank containing said dynamic phantom body; at least one dosimentry probe constructed and arranged to sense photons and electrons, said at least one dosimentry probe positioned within said dynamic phantom body; a carriage supporting said tank and said dynamic phantom body; a guideway, said carriage secured to said guideway; said tank and said dynamic phantom body positioned on said carriage; and a mechanism incrementally moving said carriage and said dynamic phantom body in a substantially vertical, radial, transverse or diagonal direction relative to said guideway; the distance between a radiation source and the axis of a beam emitted from the radiation source relative to said at least one dosimetry probe being constant; whereby movement of said tank and said dynamic phantom body through a series of locations is carried out so as to provide sufficient data to determine the proper dose of radiation required for radiotherapy treatment.
