Abstract:
An imaging x-ray detector comprising:(a) an image intensifier having:(i) a front target receiving x-rays to eject electrons into an internal volume of the image intensifier;(ii) an electron amplifier receiving the ejected electrons to amplify the same;(iii) a rear target receiving the amplified electrons to produce an optical image;(b) at least two digital cameras directed toward the rear target to produce digital signals representing different portions of the optical image as projected to a camera image plane;(c) an image correction circuit receiving the digital signals and correcting for spatial distortion of underlying different portions of the optical image captured by the digital signals; and(d) combining circuit receiving corrected digital signals from the image correction circuit and combining the digital signals to produce a spatially continuous representation of the optical image.
