Unlike conventional radiography, digital radiography does not require film. Instead, it uses a digital detector (Panel) to display radiographic images on a computer screen almost instantaneously. It allows for a much shorter exposure time so that the images can be interpreted more quickly
Furthermore, the digital images produced by this method are of higher quality when compared to conventional radiographic images. With the ability to capture quality images, this technology can be utilized to identify flaws in a material, foreign objects in a system, examine weld repairs and inspect a material for corrosion under insulation.
The four most commonly utilized digital radiography techniques in the oil & gas and chemical processing industries are Computed Radiography, Digital Radiography, Real-time Radiography and Computed Tomography
