 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.
