• RF-Induced Heating of Implanted Medical Devices in MRI Systems

    5 days ago - By IEEE Spectrum

    This sponsored article is brought to you by COMSOL. Over 80 million magnetic resonance imaging scans are conducted worldwide every year. MRI systems come in many different shapes and sizes, and are identified by their magnetic field strength. These scanners can range from below 0.55 tesla to 3 T and beyond, where tesla is the unit for the static magnetic field strength. For patients with implanted metallic medical devices, the strong magnetic fields generated by MRI systems can pose several safety concerns. For instance, high-powered magnets generate forces and torques that can cause the...
