First Claim
Patent Images
1. A method of reducing MRI image degradation caused by an implantable medical device comprising:
- providing a circuit board having a plurality of electronic components;
determining which of the plurality of electronic components are likely to cause MRI image degradation when the implantable medical device is subjected to a magnetic field during an MRI scan; and
providing at least one non-functional component on the circuit board proximate at least one of the electronic components that is likely to cause MRI image degradation;
wherein the non-functional component is formed of a material selected from the group consisting of palladium, platinum, silver, copper, manganese, aluminum, and alloys and combinations thereof.
