MR Safety of Implants: Numerical Assessment of SAR Distribution at Design-Simplified Stents of Different Lengths Placed Inside a Virtual Phantom Model Investigated at an MR Frequency of 63.9 MHz

Mark Pawlenka¹, Gregor Schaefers²

In respect of imaging quality and patient safety, temperature rises and SAR distributions, which are caused by interaction of the applied electromagnetic fields during MR exams, are of high interest for implants in MR tomography. High local SAR values are equivalent to high local temperature increases. For developing support for radio frequency (RF) induced heating experiments, SAR values were virtually investigated at design-simplified stents with different lengths inside a virtual human torso shaped phantom model
