Unlike conventional radiography, digital radiography doesn’t require film. Instead, it uses a digital detector 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 are much higher quality when compared to conventional radiographic images. With the ability to capture high quality images, the technology can be utilized to identify flaws in a material, foreign objects in a system, examine weld repairs, and inspect for corrosion under insulation.
Digital radiography is rapidly replacing film-based imaging techniques due to the elimination of manual wet processing methods as well as the associated storage and handling requirements of conventional radiographic film imaging. The advantages of digital radiography include:
