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, wherein the array of detector elements is located between the first scintillator layer and the second scintillator layer; and a first neutral density filter located between the first scintillator layer and the first detector element and/or a second neutral density filter located between the second scintillator layer and the first detector element; wherein the first detector element is 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.
