  • WIRE-FREE, DUAL-MODE CALIBRATION INSTRUMENT FOR HIGH ENERGY THERAPEUTIC RADIATION
    Publication number: 20070120064
    Abstract: An instrument for checking quality of therapeutic x-ray and electron radiation provides modes optimized for both electrons and for photons obtained by physically flipping the unit to interpose the necessary build-up material between the radiation beam and contained detectors. The invention provides an improved method of constructing ionization detectors for improved energy discrimination using such detectors and wire-free operation.
    Type: Application
