摘要： In a radiation detector, scintillation material flouoresces and the produced light is converted to electrical energy in an adjacent converter, separators are provided in spaces between the adjacent scintillators and converters. The separators may have a greater length than the adjacent scintillators, so that they will extend beyond to reduce cross-talk. The separators can extend toward the source of radiation for a height substantially greater than, and particularly five times, the height of the spaces between the adjacent scintillators to prevent X-ray scattering and function as a collimator. Optically opaque adhesive may be provided on the opposite ends of separators and pairs of scintillators and collimators, to prevent cross-talk.

摘要： A multielement radiation detector in which many elements are arranged in array. Each element includes a scintillator which is tilted with respect to the incident direction of radiant rays, and a silicon photodiode which is opposed to the plane of incidence of the scintillator. The light-receiving plane of the silicon photodiode is tilted to meet the inclination of the scintillator. Therefore, the gradient of detection sensitivity distribution is reduced in the thickness direction of the detectors.

摘要： A multi-elements radiation detector provides isolation plates each having a uniform light reflectance on the surface, excellent reproducibility and uniform performance for enhancing an X-ray spatial efficiency and a light transmission efficiency and is intended to improve a detection efficiency and an S/N of a reconstructed image so that the detector may be used for a digital X-ray imaging system, in particular, an X-ray computed tomography system. In the multi-elements radiation detector, each isolation plate isolating the adjacent elements from each other includes a thin plate made of Mo. On the surfaces of the thin plate, there are provided organopolysiloxane membranes obtained by hydrolyzing and condensing organosilicate such as CH.sub.3 Si(OCH.sub.3).sub.3 so that those surfaces are formed to be specular-reflective. On the films, there are formed reflective multi optical thin films composed of a combination of Al, MgF.sub.2 and TiO.sub.3. The isolation plate uses Mo as its material for improving its X-ray spatial efficiency. Further, the light reflectance on the surface is made as high as 85%, so that the light absorption is reduced on the surface of the isolation plate, thereby improving a light transmission efficiency and a detection efficiency. This leads to improving an S/N of an image reconstructed by an X-ray computed tomograpy system.
