Abstract

An X-ray detector assembly comprising a light attenuator of electro-chromic material, the electro-chromic material having a first electrode layer electrically coupled to a first surface of the electro-chromic material and a second electrode layer electrically coupled to a second surface of the electro-chromic material, wherein the second surface is disposed opposite the first surface, and the light attenuator having a controllable light transmission rate. The X-ray detector further comprising a scintillator deposited on the first electrode layer and a photo detector deposited on the second electrode layer. The photo detector having a sensing surface adjacent to the second electrode layer of the light attenuator. A variable power supply is electrically coupled to the first and second electrode layers of the light attenuator to provide a controllable voltage across the first and second electrode layers to control the light transmission rate of the light attenuator in real time.

Description

[0001] Intersect Application Cross Reference [0002] This application claims priority to US Provisional Patent Application No. 62 / 097,650, filed December 30, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to digital X-ray detector assemblies, and in particular to digital X-ray detector panels. Background technique [0004] With regard to various technological applications, the usefulness of digital radiography has been incalculable. Digital radiography is a mainstay in the medical field, allowing health care professionals to quickly identify and diagnose abnormalities in their patients' bodies. In addition, its use in the industrial field is becoming increasingly important for visualizing the internal composition of parts, luggage, packages and other objects, and for visualizing the structural integrity of objects and other purposes. In fact, the development of digital X-ray detect...
