| Popis: | Electrical Impedance Spectroscopy has already demonstrated the ability to distinguish different tissues types, or tumors from normal tissue, or tissues displaying diverse degrees of pathology. When applying the technique, however, the necessity to make contact with the tissue often constitutes a practical limitation. Electrical Impedance Imaging (EIT), or in a broader sense, regional impedance assessment, struggle to assess different tissue conditions out of measurements from the surface of the body. But sensitivity is very small even for tissue a few centimeters under the skin, and in-vivo measurements are often not viable.The lung offer a third approximation by introducing a catheter though a bronchoscope, which is a routine clinical procedure. Measurements have been obtained by using 3 or 4-electrode techniques and allow us to distinguish, at least, fibrotic, emphysema or neoplastic regions from normal parenchyma. New instrumental developments, clinical measurements and preliminary results are presented and discussed. |
