Computed Radiography Testing is used for non-destructive testing and examination of the internal features of a product, to characterize materials properties, and to identify defects. It is an advanced form of conventional ‘film’ radiography: instead of creating an image on radiographic film, an x-ray image is displayed directly onto a computer screen, producing real-time results.
Computed Radiography Testing
Element’s digital radiography test methods capture inclusions digitally using Digital Detector Arrays (DDA) and reusable imaging plates, instead of traditional methods using x-ray film. We use three main test methods for digital radiographic testing:
- Computed radiography (CR) is the simplest digital radiography method. The item is exposed by x-ray tubes in cabinets, the imaging plate (IP) captures the image, and the IP is digitally scanned for display onto a high resolution viewing monitor.
- Digital radiography uses a digital detector array, also known as a flat panel detector, with specialized x-ray tubes. The detector is rigid, exposure times are 70-90% shorter, and labor costs are significantly reduced.
- Computed tomography is an extension of DDA technology. It uses an automated detector motion to gather thousands of digital images at various angles to create a 3D image.
In our The Difference Between Computed Radiography (CR) and Digital Radiography (DR) blog, we explain the three common NDT digital radiography modalities, their uses, and their benefits.
