Patent ID: 8729478

Claim:
A radiographic imaging apparatus comprising: a first scintillator disposed on a first side of a substrate and having first scintillator properties including scintillator resolution and scintillator sensitivity; a second scintillator disposed on a second side of the substrate, opposite the first side, and having second scintillator properties including scintillator resolution and scintillator sensitivity different from the first scintillator properties; a plurality of first photosensitive elements to receive light from the first scintillator and having first photosensitive element characteristics including photosensitive element resolution and photosensitive element sensitivity chosen to cooperate with the first scintillator properties; and a plurality of second photosensitive elements arranged to receive light from the second scintillator and having second photosensitive element characteristics including photosensitive element resolution and photosensitive element sensitivity different from the first photosensitive element characteristics and chosen to cooperate with the second scintillator properties, where the first scintillator has a higher resolution than the second scintillator, the first photosensitive elements have a higher spatial sampling frequency than the second photosensitive elements, the second scintillator has a higher sensitivity than the first scintillator, and the second photosensitive elements have a higher sensitivity than the first photosensitive elements.
