Abstract
In magnetic resonance imaging (MRI), the powerful magnetic fields can interfere with, damage, cause premature failure in, and attract certain non-MR safe instruments. Electromagnetic ally sensitive components are eliminated in favor of MR safe components, such as ceramic piezoelectric components and bi-metallic components. Instruments that previously had to be kept a safe distance away from the main magnet (12), e.g., beyond the 5 Gauss line, while a patient was being scanned are now allowed near the patient without fear of damage to the instrument (40) or danger to the patient and medical staff or the MRI device (10).
