Electrical Impedance Tomography Based Lung Disease Monitoring

Abstract

Electrical impedance measurements can detect many diseases and disorders in the human body. Electrical Impedance Tomography (EIT) is a fast-developing medical imaging technique. In this chapter, we present some applications of EIT in lung disease detection. Existing literature in this subject has been investigated, including original research work on EIT based lung imaging, carried out in clinical settings for particular respiratory diseases: Acute respiratory distress syndrome (ARDS), Chronic obstructive pulmonary disease (COPD), Cystic fibrosis, Pneumonia, and Pleural effusion. Information about the purpose of the tests, studied subjects, the procedure followed, and results of analysis have been included as well as limitations of the studies. EIT is a promising technique in the direction of non-invasive diagnostic medicine because this can perform imaging of the human body, without posing any visible risk.
