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

Abstract

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