Three dimensional detection and imaging for human lung based on node back-projection algorithm with a 64 electrodes EIT system

Electrical impedance tomography (EIT) is a medical imaging technique in which an image of the conductivity or permittivity of part of the body is inferred from surface electrical measurements. In the paper an approach of a fast, real-time, three dimensional human lung's detection and imaging based on node back-projection algorithm with a 64 electrodes EIT system is introduced. The results shows that the system has the capability of reflection on impedance change of the thorax by the images reconstructed during one's breathing.
