Non-destructive Investigation of the Artificial Heart Valves Using Eddy Current Testing - An Innovative Approach

摘要

Many accidents leads to organ damages, bone loss or cause the failure of organ systems. Biomaterials have their application in orthopedic, vascular or in dental implants to augment and replace the loss. Many of prosthetic replacements are implanted for a long time so their correct function need to be control. Currently we have a few nondestructive testing technologies available to characterize the various features that may arise during or after the implantation. Depending on the different types of biomaterials, different features interested, different purpose of testing, the different non-destructive testing technologies should be used. This article deals with fracture detection in Bjork-Shiley Convexo Concave (BSCC) artificial heart valve where the damage of the valve can endanger the human life.
