X-RAY PRODUCTS Digital Image Receptor Product Description The PaxScan® 4030CB 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 40 x 30cm 194µm-pixel amorphous silicon FPD and real-time image and Command Processor 2. 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®XP™ 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 PaxScan® 4030CB Receptor and Command Processor 2.
