ELECTROIMPEDANCE TOMOGRAPHY IN PULMONOLOG Y

Application of a modern method of introscopy - electroimpedance tomogr aphy (EIT) for diagnosis of different types of lung diseases is descri bed. The EIT system including measurement and collecting data devices, 16-electrodes array and IBM PC 486 computer was used. The results of analysis of electrotomograms have demonstrated that the EIT-system can be introduced for detecting abnormal lung fluid levels, pulmonary ede ma, diagnosis of lung cancer, emphysema, pleuritis, hydrothorax, sarco idosis. The method provides high sensitivity to the changes in the bod y physiological state. Other advantages are: safety, fast measurements , ease of equipment transportation and maintenance, low cost.
