C-Scan refers to the image produced when the data collected from an ultrasonic inspection is plotted on a plan view of the component. The true definition according to BS EN 1330-4:2000 is the 'Image of the results of an ultrasonic examination showing a cross-section of the test object parallel to the scanning surface.' However, the C-scan does not have to be a single cross-section but often shows a combination of measurements obtained through the whole thickness.

The C-scan is used in corrosion mapping and by techniques other than just ultrasonics. It is not limited to showing amplitude but is also used to display changes in measured wall thickness or qualitative measurements in the extent of corrosion.
