First Claim
Patent Images
1. A digital radiography panel comprising:
- a scintillator screen having a light-exiting surface from a material with a first index of refraction n1;
a photosensor array having a light-accepting surface from a material with a second index of refraction n2; and
a pressure-sensitive adhesive bonding the light-exiting layer of the scintillator screen to the light-accepting layer of the photosensor array and having a third index of refraction that has a value nPSA that either lies in the range between n1 and n2, or substantially matches n1 or n2, or both.

Abstract
A digital radiography panel has a scintillator screen having a light-exiting surface from a material with a first index of refraction n1 and a photosensor array having a light-accepting surface from a material with a second index of refraction n2. A pressure-sensitive adhesive couples the light-exiting surface of the scintillator screen to the light-accepting surface of the photosensor array and has a third index of refraction that has a value nPSA that either lies in the range between n1 and n2, or substantially matches n1 or n2, or both.
