     The PaxScan® 4343CB is specifically designed to meet the

    needs of Cone Beam X-ray imaging applications featuring
    multiple sensitivity ranges and extended dynamic range
    modes. The main system components are the 43 x 43cm
    139μm-pixel amorphous silicon FPD and Command
    Processor 2LC. Excellent low-dose performance is
    achieved by combining Varian’s proprietary readout electronics
    with the high sensitivity of a custom Cesium Iodide
    scintillator. A Windows® based application program and a
    communications command (DLL) library has also been
    developed to assist OEM customers tasked with developing
    their own system interface. This imager is intended for
    incorporation into a complete X-ray system by a qualified
    equipment manufacturer.
