Abstract

This paper describes an Electrical capacitance Tomography (ECT) based sensor system designed for noninvasive cross sectional imaging of an object. It uses relative capacitance measurements of 8 electrodes placed along the peripheral of the sensor system to obtain the cross sectional image. The use of Linear Back Projection Algorithm (LBPA) to estimate the cross sectional image is demonstrated. Also, it is shown that iterative reconstruction methods can be used to further improve the results.
