摘要： A digital radiographic detector having a radiation sensing element with a particulate material dispersed within a binder composition, wherein the binder composition includes a pressure-sensitive adhesive, wherein the particulate material, upon receiving radiation of a first energy level, is excitable to emit radiation of a second energy level, either spontaneously or in response to a stimulating energy of a third energy level. There is an array of photosensors, each photosensor in the array energizable to provide an output signal indicative of the level of emitted radiation of the second energy level that is received. The radiation sensing element bonds directly to, and in optical contact with, either the array of photosensors or an array of optical fibers that guide light to the array of photosensors.
