摘要： A radiation detector is disclosed that includes a scintillation crystal and a plurality of photodetectors positioned to detect low-energy scintillation photons generated within the scintillation crystal. The scintillation crystals are processed using subsurface laser engraving to generate point-like defects within the crystal to alter the path of the scintillation photons. In one embodiment, the defects define a plurality of boundaries within a monolithic crystal to delineate individual detector elements. In another embodiment, the defects define a depth-of-interaction boundary that varies longitudinally to vary the amount of light shared by neighboring portions of the crystal. In another embodiment the defects are evenly distributed to reduce the lateral spread of light from a scintillation event. Two or more of these different aspects may be combined in a single scintillation crystal. Additionally, or alternatively, similar SSLE defects may be produced in other light-guiding elements of the radiation detector.

摘要： In a scintillator panel 2A, a glass substrate 11 with the thickness of not more than 150 µm serves as a support body, thereby achieving excellent radiotransparency and flexibility and also relieving a problem of thermal expansion coefficient. Furthermore, in this scintillator panel 2A, an organic resin layer 12 is formed so as to cover a one face 11a side and a side face 11c side of the glass substrate 11. This reinforces the glass substrate 11, whereby the edge part thereof can be prevented from chipping or cracking. Furthermore, stray light can be prevented from entering the side face 11c of the glass substrate 11, while transparency is ensured for light incident to the other face 11b side of the glass substrate 11 because the organic resin layer 12 is not formed on the other face 11b side of the glass substrate 11.
