Abstract
An in vivo impedance measurement system using a coaxial needle was developed to investigate the usefulness of impedance information for tumor diagnoses. Impedance in the range of 0 to 200 kHz was measured, and an equivalent circuit representing the tissue structure of tumors was derived. Malignant breast and lung tumors had significantly higher impedances than benign tumors, indicating the system could be useful for tumor diagnoses.<>
