A novel optical-guiding crystal scintillator (OCS) plate was developed for radiation imaging applications. OCS plates consist of a large number of tens of microns diameter scintillator crystal fibers as a core, which are filled into a glass cladding. Due to the refractive index difference between the glass cladding and the scintillator crystal core, the OCS plate has light guiding performance similar to an optical fiber. The optical-guiding function provides high resolution and sensitivity in radiation imaging, enabling sharper images and shorter imaging times. The advantage is that industrially mass-producible manufacturing processes can be applied, and the size and structure can be easily controlled compared to previously reported optical waveguide eutectics.
