Electrical Impedance Tomography in Rectangular Object Using Data Collection System Based on Absolute Boundary Potential Measurement

Abstract

One of the problems in Electrical Impedance Tomography (EIT) is the ill-possed problem occurred in the reconstruction process. Beside addition of the data number and developing of reconstruction method, using of data collection system also determine the quality of image produced. This study is aimed to propose an absolute boundary potential to adjacent method. The result showed that adjacent method with absolute boundary potential give the better result compared to the use of relative boundary potential.
