Abstract
A method of assessing lesion quality of an ablated tissue region comprising ablating at least a portion of the tissue region. The reactance of the ablated tissue region is measured at a plurality of frequencies. The lesion quality of the ablated tissue region is determined based on the measured reactance. For example, an untreated tissue reactance value and a predetermined thermally treated tissue region reactance threshold may be determined. The measured reactance at each of the plurality of frequencies is compared to the threshold to determine the lesion quality of the thermally treated tissue region. The thermal treatment of the tissue may be modified based on the lesion quality determination.
