Distortion in magnetic resonance (MR) images from implanted medical devices hinders diagnostic conclusions based on this technique. The distortion occurs because of magnetic susceptibility mismatch between the implant and the surrounding tissue. It is known that the magnetic susceptibility of metals can be tailored through alloy chemistry. This methodology can provide a potential path for the development a magnetic susceptibility-matched alloy for implant usage in the brain. Knowing appropriate processing-structure-property relationships, a prototype model system were developed to elucidate the effectiveness of the technique. This study shows how a solid-solution metallic alloy can be utilized to match magnetic susceptibility of the human brain to create clear MR images. In addition, a biocompatible alloy with appropriate thermoelectric and mechanical properties will be detailed for use as an electrode pad array utilized on the brain.
