Abstract
The x-ray imaging system comprises an x-ray source for producing an x-ray beam and an x-ray detector. The x-ray detector comprises a solid state integrated circuit having a silicon substrate and a plurality of charge storage devices. A circuit is provided for placing a charge on the charge storage devices and the integrated circuit is disposed in an x-ray permeable material. The detector is positioned in an x-ray beam such that the charge is dissipated by secondary radiation produced by interaction between the x-ray beam and the silicon substrate of the integrated circuit.
