Digital Radiography Testing (DRT) is an advanced non‑destructive testing (NDT) technique that uses digital detectors instead of traditional radiographic film to inspect the internal integrity of components. DRT provides instant, high‑resolution digital images, enabling faster inspections, improved defect detection, and efficient data management across industrial applications.

What is Digital Radiography Testing (DRT)?

DRT is a modern radiographic method that employs X‑ray or gamma radiation in combination with digital sensors—such as flat‑panel detectors or imaging plates—to capture internal images electronically. Unlike film radiography, DRT eliminates chemical processing and allows images to be viewed, enhanced, and analyzed within seconds of exposure.

Key Technical Features

Filmless radiographic inspection

Immediate image acquisition and display

Digital image enhancement (contrast, zoom, filtering)

Electronic storage and easy data sharing

Reduced radiation exposure compared to film RT

What DRT detects

Digital Radiography Testing is effective for identifying:

Weld defects (porosity, lack of fusion, slag inclusions)

Cracks and voids

Corrosion and erosion

Wall thickness variations

Casting and fabrication defects
