Numerical Simulation of Conductivity Changes in the Human Thorax Caused by Aortic Dissection

In case of an aortic dissection (AD), the aortic shape as well as the blood flow will be altered in the region concerned. Based on the thoracic electrical bioimpedance technique that allows to identify and quantify conductivity changes by measuring the impedance on the thorax, a numerical simulation model for investigating effects caused by ADs is proposed. In order to find a simple non-invasive method for the detection of ADs, the possibilities and limits of applying a bioimpedance technique are shown in this paper.
