Digital Radiography (DR) is a modern approach to radiography that captures images using digital detectors instead of film. It offers advantages like immediate results, easier processing, and reduced radiation exposure. Within digital radiography, Profile Radiography (also known as Tangential Radiography) is a specific technique used to inspect the wall thickness of pipes and other cylindrical components. It's particularly useful for detecting corrosion, erosion, and deposits, especially in areas inaccessible to traditional methods.
