摘要：
A method and system for assessing lesion formation in tissue is provided. The system includes an electronic control unit (ECU) configured to acquire magnitudes for a component of a complex impedance between an electrode and tissue, and the power applied to the tissue during lesion formation. The ECU is configured to calculate a value responsive to the complex impedance component and the power. The value is indicative of a predicted lesion depth, a likelihood the lesion has reached a predetermined depth, or a predicted tissue temperature. The method includes acquiring magnitudes for a component of a complex impedance between an electrode and tissue and the power applied during lesion formation. The method includes calculating a value responsive to the complex impedance component and the power, the value being indicative of a predicted lesion depth, a likelihood the lesion has reached a predetermined depth, and/or a predicted tissue temperature.
