Abstract
The invention provides methods and apparatus for detecting radiation including x-ray photon (including gamma ray photon) and particle radiation for dental x-ray imaging, radiation monitoring, and related industrial and scientific applications. Flat or shaped small (and small hybrid) area storage phosphor plates, available in multiple sizes, are encased in SP-carriers and used as detectors for intraoral dental x-ray imaging as a replacement for analog x-ray film and digital x-ray cameras, offering good detection efficiency, high spatial and contrast resolution, and a wide dynamic range. After removal of the SP-carrier, a small area storage phosphor plate is loaded into a dental storage phosphor scanner for readout. Intermediate and large area storage phosphor plates (including hybrid versions) are suitable for non-intraoral dental x-ray imaging. Suitable storage phosphors may be used in radiation monitoring, replacing current detectors employed in a film badge format. Simple external readers or electronic SP-carriers can provide data readout and thus enable dosimetry.
