Digital radiography is an advanced inspection technology which creates an X-ray image that is displayed live on a computer screen without the need for developing chemicals or intermediate scanning.
This works by converting X-ray radiation into an equivalent electric charge that is then used to create a digital image through a detector sensor.
The technique provides high quality digital images with good signal to noise ratio and an improved dynamic range, providing a high sensitivity for radiographic applications. A component with varying thicknesses and densities can often be X-rayed in a single digital radiographic image, using the high dynamic range to pick out subtle variations in thick and thin sections alike.
Digital radiography displays X-ray images directly onto a computer screen, allowing the user to see instantly whether the shot has been optimally setup so the orientation of the part can be adjusted accordingly, and often remotely, using a built-in manipulation system.
Compared to film radiography, where it can often take over 10 minutes to produce a radiograph from the point of exposure, digital radiography can reveal the inner features of a component in a matter of seconds.
