Abstract

Embodiments of methods/apparatus according to the application can include radiographic imaging device comprising an imaging array of pixels or a plurality of photosensors including a first side to receive light from a scintillator and a second side to pass second light responsive to impingement of the scintillator light and a reflective layer configured to reflect third light responsive to impingement of the second light. Exemplary photosensors can absorb a prescribed amount of the scintillator light received through a first transparent side and the third light received through a second transparent side. Exemplary reflective arrangements can be selected based upon scintillotor emission characteristics and/or photosensor absorption characteristics. Embodiments of radiographic detector arrays and methods can reduce photosensor thickness to reduce noise, reduce image lag and/or increase charge capacity. Embodiments can maintain the quantum efficiency of a reduced thickness photosensor.
