Digital radiography is a non-destructive testing (NDT) technique that uses X-rays or gamma rays to inspect the internal structure of an object. The radiation is transmitted through the object, and the resulting image is captured by a digital detector.

In digital radiography, the image is immediately displayed on a computer screen, allowing the operator to view and analyze the image in real-time. The digital image can also be stored, transmitted, and manipulated for further analysis.

One advantage of digital radiography over film-based radiography is that it allows for real-time image processing and analysis. Digital radiography also offers the ability to enhance the contrast and resolution of the image, as well as the ability to measure dimensions and identify defects within the object being inspected.

Digital radiography is commonly used in a variety of industries, including aerospace, automotive, construction, and manufacturing, to inspect welds, castings, and other structural components for defects. It is also used in medical imaging to diagnose and monitor medical conditions.
