Abstract
(EN)
An imaging apparatus (200) includes: a first scintillator layer (202) configured to provide first image signals with a first quantum efficiency and a first spatial resolution; a second scintillator layer (204) configured to provide second image signals with a second quantum efficiency and a second spatial resolution, wherein the first quantum efficiency is lower than the second quantum efficiency, but the first spatial resolution is higher than the second spatial resolution; and an image combiner (220) configured to combine the first image signals and the second image signals.
