摘要： PROBLEM TO BE SOLVED: To provide a digital radiographic detector that is suited for intra-oral imaging and that provides optical coupling between the photosensor array and the phosphor layer. SOLUTION: A digital radiographic detector has a scintillator element having a particulate phosphor dispersed within a binder composition, wherein the binder composition is a pressure-sensitive adhesive with the particulate phosphor emitting a light which corresponds to the level of incident radiation. There exists an array of photosensors wherein each photosensor in the array provides an output signal, indicative of the level of emitted light that is received. The scintillator element bonds directly to, and is in optical contact with, either the array of photosensors or an array of optical fibers that guide light to the array of photosensors.
