lateral resolution

lateral resolution

the resolution of objects in a plane perpendicular to the axis of an ultrasound beam. It is a measure of the ability of the system to detect closely separated objects, such as adjacent blood vessels.

When inspecting heavy wall pipelines in particular, the SIC measurement provides precise depth-sizing results for shallow internal corrosion (detection threshold [greater than or equal to] 1 mm) while assisting MFL defect identification and depth sizing by permitting better distinction of individual pits in dense clusters due to its high lateral resolution in defect surface measurement.
