Guest Editorial for Advances in Tomography for Industrial and Medical Applications Special Section

Initially, electrical tomography techniques were developed for industrial applications. Recently, electrical tomography for medical application has attracted strong interest and several research groups over the world are working on this topic. In this special session, four papers are about electrical impedance tomography (EIT) for medical application, including cell, thorax, and bladder. One paper is about electrical capacitance tomography (ECT) for industrial application, i.e., velocity profile measurement in fluidized beds. Because electrical tomography has been around for many years, hardware design of electrical tomography systems is relatively mature. In contrast, there is plenty room for research in image reconstruction algorithms. In this special session, most papers are about improvement in image reconstruction, rather than in hardware. We hope that this special session provides a good reference point for researchers, who are active in the relevant field and will serve as a catalyst to trigger further investigation.
