X-ray detector for use in layered structure, particularly for medical diagnostic device, has two detector layers arranged in radiation direction in superimposed manner

摘要

#CMT# #/CMT# The x-ray detector (2) has two detector layers (5,7) arranged in radiation direction (4) in a superimposed manner. One detector layer has a scintillator layer (8) and another detector layer has a semiconductor direct converter layer (6). Both the detector layers are designed for detecting the radiation of different energy. The semiconductor direct converter layer is made of cadmium telluride, cadmium zinc telluride, gallium arsenide or silicon. #CMT# : #/CMT# An independent claim is included for a method for producing an x-ray image. #CMT#USE : #/CMT# X-ray detector for use in layered structure, particularly for a medical diagnostic device, particularly computer tomography apparatus. #CMT#ADVANTAGE : #/CMT# The X-ray detector has two detector layers, arranged in radiation direction in a superimposed manner, where both the detector layers are designed for detecting the radiation of different energy, and hence ensures improved image properties and tissue separation in an obtained image. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an x-ray detector structure. 2 : X-ray detector 4 : Radiation direction 5,7 : Detector layers 6 : Semiconductor direct converter layer 8 : Scintillator layer.
