X-RAY PRODUCTS Amorphous Silicon Digital X-Ray Detector Product Description The 2020+ has been specifically designed to meet or exceed the unique imaging requirements for next generation cardio-vascular diagnostic imaging equipment and mobile C-arms. The high sensitivity of the CsI scintillator combined with proprietary noise management techniques allows for excellent low-dose imaging performance that rivals image intensifier tube (IIT) devices. Other features include an optimal 2 cm border between the active matrix and the edge of the receptor, further optimization of the pixel architecture, and an improved Command Processor with extended mode memory and faster clock speed. 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.
