Feasibility of RF Ablation at the Larmor Frequency for RF Field Visualization

Kim Shultz¹, Pascal Stang¹, John Pauly¹, Greig Scott¹

The process of RF ablation treatment is often imaged with MRI using temperature mapping. MRI has the additional cabability of imaging the RF fields from the ablation currents if the ablation is performed at the Larmor frequency. We demonstrate the feasibility of performing ablation at 64 MHz with temperature and impedance monitoring and show the change in RF field maps from the ablation procedure.
