RF current density imaging (RFCDI) can potentially be used to monitor and predict RF ablation patterns. In order for RFCDI to be useful in a clinical setting, the acquisition process must be accelerated. Using the Actual Flip-Angle Imaging (AFI) technique to measure the magnitude and phase of the RF fields allows us to acquire volumetric current images with scan times of only a few minutes.
