RF Field Visualization of RF Ablation at the Larmor Frequency [PDF]

IEEE Transactions on Medical Imaging, 2012
Radio-frequency ablation (RFA) is an effective minimally invasive treatment for tumors. One primary source of difficulty is monitoring and controlling the ablation region. Currently, RFA is performed at 460 kHz, for which magnetic resonance imaging (MRI) could play a role given its capability for temperature monitoring and tumor visualization.
