Abstract: 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.

Abstract: A radiation detector (24) for an imaging system includes a two-dimensional array (50) of nondeliquescent ceramic scintillating fibers or sheets (52). The scintillating fibers (52) are manufactured from a GOS ceramic material. Each scintillating fiber (52) has a width (d2) between 0.1 mm and 1 mm, a length (h2) between 0.1 mm and 2 mm and a height (h8) between 1 mm and 2 mm. Such scintillating fiber (52) has a height (h8) to cross-sectional dimension (d2, h2) ratio of approximately 10 to 1. The scintillating fibers (52) are held together by layers (86, 96) of a low index coating material. A two-dimensional array (32) of photodiodes (34) is positioned adjacent and in optical communication with the scintillating fibers (52) to convert the visible light into electrical signals. A grid (28) is disposed by the scintillating array (50). The grid (28) has the apertures (30) which correspond to a cross-section of the photodiodes (34) and determine a spatial resolution of the imaging system.
