Abstract

See full text

Disclosed is an ultrasonic IRIS inspection system and a method of providing automatically compensated concentric B-scans by means of curve-fitting the unadjusted tube boundaries from inspection data, and from the curve fitted theoretical circle, using non-linear regression analysis to determine an adjusted center. The off-center distance between the adjust center and the misaligned center is then used to produce concentric inspection result by compensating the unadjusted inspection result with the off-center distance.
