Description

Computer models of ultrasonic beams can be used to accurately predict fields radiated from transducers [1,2]. Given these fields and reciprocity relations [3] the responses from reflectors of known shape can be calculated. Often scan sensitivity for an inspection is quantified relative to the response from a flat bottomed hole (FBH). Because the FBH is a simple known shape, a computer simulation with an ultrasonic measurement model [4] can be used to model and refine the inspection.
