Abstract:
1. A modular radiation beam analyzer for measuring the distribution and intensity of radiation produced by a radiation source comprising: a phantom tank constructed and arranged to contain a material having a density approximating that of a human body, said phantom tank sized to accommodate an X-axis module, a Y-axis module and a Z-axis module of said radiation beam analyzer; said X-axis module including an X-axis guideway extending substantially across an upper portion of said phantom tank, including an X-axis carriage slidably secured to said X-axis guideway for controlled movement along the length thereof; said Z-axis module including a Z-axis guideway, said Z-axis guideway secured to said X-axis carriage for movement therewith, including a Z-axis carriage slidably secured to said Z-axis guideway for controlled movement along the length thereof; said Y-axis module including a Y-axis beam member, said Y-axis beam member secured to said Z-axis carriage for movement therewith; at least one radiation detection probe secured to said Y-axis beam member, said radiation detection probe constructed and arranged to sense photons and electrons; a controller electrically connected to said X-axis and said Z-axis for providing electrical signals thereto, whereby said controller includes a manually operable member for instructing an input of a desired direction for manually controlled movement of said X and Z axes carriages, whereby movement of said dosimetry probe through a volumetric space provides data to determine radiation density and distribution of a radiation beam.
