Title:
FLAT PANEL DETECTOR AND FABRICATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/001440
Kind Code:
A1
Abstract:
Disclosed are a flat panel detector and a fabrication method therefor. The flat panel detector comprises a first optical assembly, and the first optical assembly has a first side and a second side along the thickness direction of the flat panel detector and comprises: a first scintillator layer, for converting at least a portion of rays into first visible light, and a first light conducting structure stacked with the first scintillator layer and used for conducting the first visible light. The flat panel detector further comprises a first image sensor assembly, stacked with the first optical assembly and used for receiving the first visible light. The first image sensor assembly comprises a first image sensor and a second image sensor which are disposed on the first side and the second side of the first optical assembly, respectively. By providing the second image sensor, a portion of the first visible light emitted from an upper surface of the first scintillator layer is able to reach the second image sensor for imaging, thus avoiding the loss of the first visible light due to propagation within the first scintillator layer.
