Radiofrequency ablation monitoring using calibrated CDV in a clinical balloon catheter with an applied voltage of $V_{\text{RMS}}=25$~V at 500~kHz for 10~s. In contrast to Fig.~\ref{fig:Exp_CDV1}, the region with increased CDV (purple) reached the lamina propria at $t=$~6--7~s and eventually reaching all the way through the muscularis mucosa at $t=$~8--10~s. The RF source was turned off at $t=$~10~s.
