SCINTILLATING FIBER DOSIMETER ARRAY

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 ener gy in response to a predetermined type of radiation, and are coupled to collection optical fiber s that transmit the optical energy to a photo-detector for conversion to an electrical signal. T he detectors may be embedded in one or more modular, water-equivalent phantom slabs. A repeatabl e 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 differe nt orientations relative to a transmission axis of an incident radiation beam.
