Small diameter pipe inspection


In this case, a cylindrical reconstruction is being done for small diameter pipe inspection using sizing with corner effect mode (TTT) for better defect sizing. Both TFM technique and sectorial scan are illustrated.
For outside diameter defects, both modes account for the rebound off the inner curved-surface to display a scaled image.
