|1. (WO2017190538) X-RAY DETECTION METHOD AND X-RAY DETECTOR|
NUCTECH COMPANY LIMITED
|Title:||X-RAY DETECTION METHOD AND X-RAY DETECTOR|
An X-ray detection method and an X-ray detector. The method comprises: dividing an energy range of a photon emitted by an X-ray source into N energy windows, wherein N is an integer greater than 0; based on linear attenuation coefficients of a substance of interest and a background substance of an imaging target, acquiring a weight factor of each energy window in the N energy windows; based on the weight factor of each energy window in the N energy windows, acquiring a weight factor matrix of M output channels of an X-ray detector, wherein M is an integer greater than 0; and based on the number of photons with an energy range falling within each energy window in the N energy windows, and the weight factor matrix, acquiring output results of the M output channels.
