On the Consequences of Wrapping Patients with RF Shielding Materials

Electromagnetic field simulations have been used to evaluate the effect on SAR and RF power demand during normal RF exposure, using the system body coil, for a human body model partially wrapped with a carbon (graphite) sleeve intended to shield parts of the body against the applied RF field. The presence of an RF absorbing/shielding sleeve creates an additional load inside the body coil which causes re-distribution of the E-field and requires increased input power together resulting in elevated global and local SAR.
