Advanced Digital Radiography Systems and Image Processing Operations in Radiography Inspection

Abstract

Rapid industrial and technological growth throughout the world makes it necessary to develop new materials along with advanced Non-Destructive Testing (NDT) Methods to ensure their quality without premature failures. The complex modern system, where materials are required to perform consistently with optimum efficiency, demands stringent quality control of engineered components. With the increase in power of personal computing systems, all inspection data are being digitized to analyze signals effectively. Radiography is not an exception. New advanced radiography systems have been developed that are gradually replacing conventional film radiography. Fluoroscopy systems, image plate based computer radiography systems and flat panel technology are new additions in digital radiography. The advantages of digital radiography are enormous in terms of speed, dynamic range, reusability, etc. Also, digital radiography information can be shared with any part of world in nearly instantly through the internet.
