DUAL ENERGY X-RAY DETECTOR USING MULTIPLE GAS ELECTRON MULTIPLIER DETECTOR, AND X-RAY IMAGE CAPTURING SYSTEM

摘要

The present invention relates to a dual energy X-ray detector using a multiple gas electron multiplier (GEM) detector, and an X-ray image capturing system. The present invention comprises: a GEM chamber; a cathode; a first detector for low energy X-ray detection having arranged in parallel a first scintillator reacting with a low energy x-ray, a GEM foil and a first anode; and a second detector for high energy X-ray detection having arranged in parallel a second scintillator reacting with a high energy x-ray, a GEM foil and a second anode, wherein the first detector and the second detector are arranged in series inside the GEM chamber in the direction of the X-rays.
