ENERGY FILTER-TYPE DUAL ENERGY X-RAY IMAGING SYSTEM USING GAS ELECTRON MULTIPLIER DETECTOR, AND X-RAY IMAGE CREATION METHOD THEREOF

摘要

The present invention relates to an energy filter-type dual energy X-ray imaging system using a gas electron multiplier detector, and an X-ray image creation method thereof. The present invention comprises: a rotation part which is rotatable about a central axis and has a fixed frame extending in both directions along a straight line from the central axis; an X-ray source which is fixedly coupled to the lower end of the end part on one side of the fixed frame; a low energy X-ray filter part which is installed in front of the X-ray source and blocks a low energy X-ray in any one radiation region among radiation regions in the left/right directions of the X-ray; a gas electron multiplier detector which is fixedly coupled to the lower end of the end part on the other side of the fixed frame; and an image processing part which synthesizes and processes an image detected by the gas electron multiplier detector, wherein the image processing part creates a dual energy X-ray image by synthesizing a first image and a second image, the first image being created by capturing a subject positioned at the lower part of the central axis, and the second image being created by capturing the subject from a position where the fixed frame is rotated by 180 degrees.
