The PaxScan® 3030D is a real-time digital X-ray imaging device commonly referred to as a flat panel detector (FPD). The main system components are the 30 x 30cm 194^m-pixel amorphous silicon FPD and universal power supply. Excellent low-dose performance is achieved by combining Varians proprietary readout electronics with a custom Cesium Iodide scintillator. A Windows® XP based application program and a communications com- mand (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.
