Digital computed radiography replaces film radiography

摘要

Computerised Information Technology Ltd (CIT), UK, has launched its filmless, high definition, digital computed radiography technology, suitable for NDT inspections, replacing conventional film radiography. CIT's digital computed radiography (CR) is an electronic system that enables radiographic images of products under examination to be generated and displayed on radiographic monitors. The image is captured directly on a phosphorous CR plate and scanning transmits the image on the viewing monitor. No intermediate steps or film processing are required to capture the image, and images are then archived on CD/DVD media. Digital CR can inspect products that have welds or castings in metallic and non-metallic components for flaws that match the fine grain film radiography. With the acceptance of CEN and ASME standards, users in all areas of industry are replacing the conventional method of NDT film radiography with the digital CR technology.
