| Research Abstract |
Generally, computed tomography (CT) has been used for diagnosis of lung disease. However, a patient needs to go to a laboratory for CT measurement that is very hard for a patient. Therefore, there is a need for local regional monitoring of lung lesions at the bedside. Electrical Impedance Tomography (EIT) has become a feasible technique to evaluate lung function. However, it is yet to be considered as a clinically acceptable method for that. We had proposed the use of 'lung density' as an absolute measure of lung function using EIT data sets, but had not compared it with clinical results from patients with lung disease. In this study, we had developed special software to estimate lung density and compared CT values (HU) and lung density (kg/m3), though representing different physical properties of lung tissue. Furthermore, a wearable EIT had been developed that could be easy to use and very compact.
