    摘要: According to one aspect, a planar and volumetric dosimeter for use with a radiotherapy machine having a radiation source. The dosimeter includes a scintillating assembly including a plurality of scintillating optical fibers and configured to generate a light output in response to incident dose distribution thereon from the radiation source, and a photo-detector operable to convert optical energy emitted by the scintillating assembly to electrical signals for determining actual two-dimensional (2D) or three-dimensional (3D) dose distribution incident on the scintillating assembly using a tomographic reconstruction algorithm.

    摘要: A radiation dosimetry apparatus and method use a scintillating optical fiber array for detecting dose levels. The scintillating optical fiber detectors generate optical energy in response to a predetermined type of radiation, and are coupled to collection optical fibers that transmit the optical energy to a photo-detector for conversion to an electrical signal. The detectors may be embedded in one or more modular, water-equivalent phantom slabs. A repeatable connector couples the collection fibers to the photo-detector, maintaining the fiber ends in a predetermined spatial relationship. The detector fibers may be distributed as desired in a three-dimensional detection space, and may be oriented with their longitudinal axes at different orientations relative to a transmission axis of an incident radiation beam. A calibration method uses two measurements in two spectral windows, one with irradiation of the scintillator at a known dose and one with only irradiation of the collection fiber.
