Abstract
Abstract A detector comprising a plurality of densely packed x-ray detectors arranged into an array. Each detector preferably comprises a scintillator element which is optically coupled to a photodetector element, preferably with a fiber optic link. Each photodetector element is preferably optically separate from adjacent photodetector elements. The detector array preferably includes integral alignment means to align the scintillator elements with the photodetector elements. The scintillator array elements are preferably formed from materials which possess a fast response and a minimum afterglow time.
