Abstract
An X-ray detecting apparatus for the detection and localization of ionizing X-ray or gamma radiation in radiography, the apparatus comprising: an X-ray detector including: conversion means for converting incident x-ray photons of an incident x-ray photon beam into detectable electrical charges; and amplification means for amplifying the electrical charges in the detector by an non-linear amplification gain factor the non-linear amplification gain being characterized by a decrease in amplification gain at high fluxes of incident x-ray photons; and amplification gain adjustment means configured to vary the amplification gain of the amplification means according to the emission parameters of an x-ray source providing the incident x-ray photon beam for the radio-graphic examination to be performed and/or the transmitted beam received by the detector from the x-ray source via the subject being imaged. A radiographic imaging device and a method of operating the radiographic imaging device are also presented.
