| Zusammenfassung | Concern has been recently raised about the possible heating of massive metallic implants, in particular hip prostheses, due to the gradient fields used in MRI. Thus, this contribution discusses the computation of the power density deposited by the magnetic field into the implant, which represents the first step to estimate the thermal heating. The analysis is based on numerical simulations, performed through a computational formulation applied to an anatomical model of the body. The results provide evidence of the role of the three gradient coil axes and of the different harmonic components of the signals in this power deposition process. |
