Title
(EN) Defect discrimination apparatus, methods, and systems
Abstract
(EN)

An apparatus and a system, as well as methods, operable to include acquiring eddy current data from at least two concentric pipes, determining spatial frequency content of the eddy current data, and determining locations of defects in each of the pipes based on the spatial frequency content.
