Inspection of conductive prosthetic replacements using electromagnetic methods of non-destructive testing

摘要

This paper describes the use of electromagnetic methods of non-destructive testing for detecting ofinhomogeneities presence in a prosthetic replacement with focus on strut fractures in prosthetic heart valves. In the first partof this paper there are described a basic principle of eddy current testing, heart valve replacement and materials which areusually used for it. The experimental part contains description of simulated problem, obtained simulation results and theirinterpretation for use in medicine.
