Systems, methods and computer storage mediums accurately measure wall thickness in a region of interest included in complex curved structures. Embodiments of the present disclosure relate to generating a wall thickness loss distribution map of a region of interest that provides an accurate representation of wall thickness for the region of interest included in a complex curved structure. The wall thickness loss distribution map is generated from a two-dimensional model of the wall thickness loss distribution of the region of interest. The two-dimensional model is converted from a three-dimensional representation of the wall thickness loss distribution of the region of interest. The three-dimensional representation of the wall thickness is generated by ultrasonic waves generated by a transducer system that propagated through the region of interest.

Measuring wall thickness loss for a structure

A method and an apparatus for guided-wave tomographic measurement or monitoring of wall thicknesses of the walls of pipes and similar structures are disclosed. The method is characterized in that use is made of transducers () preferably positioned in at least two groups of a plurality of transducers ('-&#x2033;) arranged in a spaced apart pattern on the external surface of the structures, the transducers individually transmit ultrasound signal into the pipe wall, in that each ultrasound signal propagates within the pipe wallfrom the transmitting transducer and is received at one or several receiving transducers, and the received ultrasound signal is converted to an electrical signal by the receiving transducers and recorded by the transceiver (). Measurements are performed by using a further plurality of transducers () that are placed apart from the two groups of a plurality of transducers (&#x2032;-&#x2033;). There is also disclosed a method for guided-wave tomographic measurement or monitoring of wall thicknesses in the walls of pipes and similar structures producing a set of measurement data by using the apparatus.
