Title:
X-RAY SENSING DEVICE CAPABLE OF ACQUIRING DUAL-ENERGY IMAGE THROUGH ONE-TIME PHOTOGRAPHY, AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/128019
Kind Code:
A1
Abstract:
Provided are: an X-ray sensing device comprising a scintillator, a color filter, and a CMOS image sensor; and a method for processing an image acquired using same. The X-ray sensing device according to an embodiment of the present invention comprises: a dual-layer scintillator provided as a two-layer scintillator in order to convert energy spectra of different bands into visible light of different colors; a color filter arranged at the rear end of the dual-layer scintillator; and a CMOS image sensor arranged at the rear end of the color filter so as to acquire and process an image having passed through the dual-layer scintillator and the color filter. Therefore, a dual-energy image including X-ray energy of different bands is acquired through one-time photography and is processed as an image, and thus the amount of information that can be obtained through an X-ray image can be increased.
