Impedance tomography and its application in deep venous thrombosis detection

The authors have developed an impedance imaging prototype system and tested its functionality. They describe some enhancements made to their previous system and three algorithms for reconstructing impedance images. The system is capable of reconstructing cross-sectional impedance distributions from surface measured data. They discuss some experimental results with the saline tank and a preclinical study of applying the electrical imaging technique to detect deep venous thrombosis (DVT). Other potential applications include monitoring pulmonary edema, imaging the lungs, and noninvasive temperature monitoring during hyperthermia treatment.<
