    摘要: A method and system are disclosed for recognizing tissue types. Electrical signals are applied to tissue 120 via electrodes 110, 112. Circuitry 106 and the signal processor 116 are used to measure impedance magnitude and phase at a plurality of frequencies. At least the phase information at the plurality of frequencies is compared with phase information of known tissue types. Based on the comparison, the tissue 120 may be assigned to one of the known tissue types.
