FERROMAGNETICS IN MAGNETIC RESONANCE IMAGING

Abstract

Useful tool in diagnostic radiology is magnetic resonance imaging (MRI). Scanning with this system can cause interaction between ferromagnetic used for creation of implants and magnetic fields of MRI. In order to determine magnetic field distribution the integral equation governing magnetic scalar potential is formed with induced magnetic charges on the thin arbitrary shaped ferromagnetic plate as unknowns. The obtained integral equations will be numerically solved using Equivalent electrodes method. Application of ferromagnetic materials in biomedical implants will be observed. Also, possible risk of interaction of these implants and MRI devices is analyzed.
