RF-induced Heating Estimation of a Stent in a 3T MRI using Transfer Function Approach with a table-top E-field generator

Motivation: The TF validation process is time-consuming work. Here, we reduced the burden of TF approach using a low power tabletop E-field generator. Goal(s): Using the TF approach to estimate the RF-induced heating of the stent tip at 3T using a E-field generator and compared predicted values against the estimated values. Approach: TF of the stent was measured via piX method at 128MHz . TF was validated by exposing the device under diverse test fields using table-top E-field generator. The body coil was used to evaluate the TF approach. Results: The stent tip heating was estimated using TF approach with a low-power E-field generator. Impact: TF approach could aid estimating the RF-induced heating, not only active implantable device, but also elongated passive implantable device. A compact E-field generator can be used for TF validation.
