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.
perpendicular to the mucosa) is necessarily less than the lateral resolution (tangential to the mucosa) because of the physical properties of confocal microscopes.
The highly focused x-ray beam allows a lateral resolution of about 30 microns.
Avoiding wavelet stretch provides long-offset imaged data, far beyond what is reached in conventional migration and results in images from the target with improved vertical and lateral resolution and angular illumination.
