Abstract
An imaging device includes: a first scintillator layer; an array of detector elements, wherein the array of detector elements comprises a first detector element; a second scintillator layer configured to receive radiation after the radiation has passed through the first scintillator layer and the array of detector elements, wherein the array of detector elements is located between the first scintillator layer and the second scintillator layer; a first electrode located closer to the first scintillator than the second scintillator; and a second electrode situated between the second scintillator and the first detector element; the first detector element configured to generate a first electrical signal in response to light from the first scintillator layer, and to generate a second electrical signal in response to light from the second scintillator layer; the second electrode configured to allow the light from the second scintillator layer to reach the first detector element.
