Abstract
This disclosure defined by this invention sets forth an X-ray detector including a scintillator. The scintillator is formed with a doped alkali halogenide and is constructed with an array of photodiodes including at least one photodiode containing a semiconductor material with a color transformer. The color transformer contains a photoluminescent phosphor and may be arranged between the scintillator and the array of photodiodes. One benefit of the scintillator, and an x-ray detect which includes the scintillator, is that it enables a larger part of the X-radiation to be used for image analysis.
Claims8
An X-ray detector comprising a scintillator including a doped alkali halogenide comprising an array of photodiodes including at least one photodiode containing a semiconductor material, wherein a color transformer containing a photoluminescent phosphor is arranged in a layer and disposed between the scintillator and the array of photodiodes without an intermediate air layer.
