Digital Detector Array (DDA) is an advanced digital radiography system for inspecting, scanning and capturing a pipe or samples along with an X-ray source. It produces images that develop with little or no processing or exposure time required and can be used for a variety of tests, examinations and inspections. DDA radiography uses an industrial flat panel detector to detect structural or manufacturing defects without damaging the object being inspected.

Unlike computed radiography (CR), DDA allows you to see an image immediately without processing it on a computer. Conventional RT with film, an image develops without processing (and instantly). The digital image serves as a chronological record of the condition of the component; it can be stored, retrieved, and compared as easily as any other digital data.

The comparison between DDA and other radiography techniques:
Compared to conventional film-based systems and processes, DDA systems are faster, more accurate and more efficient. Image results are processed immediately and transmitted directly to your computer for analysis without waiting for film replacement, processing, chemical-based development, and storage. This efficiency means that interpretor can review the information in an image in real time and act accordingly. In addition, digital images are portable. DDA also makes it possible to produce images in normal lighting conditions.

DDA radiography could offer an efficiency advantage over computed radiography (CR) when viewing larger defects. Whereas with CR an image can only be displayed after the data has been fed into a computer and interpreted, with DDA the image can be viewed immediately. With DDA radiography, your organization can save time, reduce costs and increase productivity.
