Comparative analysis of different hip implants within a realistic human model located inside a 1.5T MRI whole body RF coil

Temperature rise in surrounding tissues of a large orthopedic metallic implant subject to MRI is a significant point of concern today. Numerical electromagnetic and thermal modeling offers a way to model this complex problem with a sufficient degree of accuracy. We developed a workflow for realistic implant modeling, which includes an MRI coil, a multi-tissue human model, and accurately registered hip implants. We also obtained differences in the power loss density rises generated due to the presence of three hip implants placed in a phantom or a realistic human model, located inside a 1.5 T coil.
