DIGITAL RADIOGRAPHIC DETECTOR WITH BONDED PHOSPHOR LAYER
First Claim
1. A digital radiographic detector comprising:
- a radiation sensing element comprising a particulate material dispersed within a binder composition, wherein the binder composition comprises 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; and
an array of photosensors wherein each photosensor in the array is energizable to provide an output signal indicative of the level of emitted radiation of the second energy level that is received,wherein 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.

Abstract
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.

10. A digital radiographic detector comprising:
-
a radiation sensing element comprising a particulate material dispersed within a binder composition, wherein the binder composition comprises a pressure-sensitive adhesive, wherein the particulate material is excitable to emit light corresponding to a level of incident radiation, either spontaneously or upon receiving a stimulating energy; an array of photosensors wherein each photosensor in the array provides an output signal indicative of the level of emitted light it receives; and an array of optical fibers disposed to guide light emitted from the scintillator element toward photosensors in the array of photosensors, wherein the scintillator element bonds in optical contact to the array of optical fibers. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 20, 21)
