Title:
DUAL-ENERGY RADIATION FLAT PANEL DETECTOR, MANUFACTURING METHOD, AND DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/142431
Kind Code:
A1
Abstract:
The present invention provides a dual-energy radiation flat panel detector, a manufacturing method, and a detection system. The detector sequentially comprises, in an X-ray incident direction, a first scintillator layer, a photoelectric sensor array, a transparent substrate, a ray filtering layer and a second scintillator layer, wherein the photoelectric sensor array layer comprises first photosensitive pixels and second photosensitive pixels which are alternately distributed, the first photosensitive pixels and the second photosensitive pixels have opposite photosensitive directions to respectively achieve low-energy X-ray imaging and high-energy X-ray imaging, and the ray filtering layer is used for filtering low-energy X-rays and preventing light emission and scattering of the second scintillator layer. In the present invention, a single-layer photoelectric sensor array is used for simultaneously acquiring dual-energy, i.e. low-energy and high-energy, spectrum object images, and the ray filtering layer is used for filtering low-energy rays and preventing light emission and scattering of the second scintillator layer, facilitating improvement of the material resolution capability of a detector, improving the image quality, and improving the diagnosis accuracy. Furthermore, the structure is greatly simplified, and the volume can be greatly reduced, facilitating reduction of the system cost.
