Abstract

It is known to the thoracic EIT community that inaccurately known boundary shape and electrode positions can potentially cause major artefacts in reconstructions. These problems are addressed in this work by using an MR (Magnetic Resonance) image to approximate the boundary shape, and a forward problem perturbation technique to calculate an electrode movement Jacobian. Using real thorax EIT data from the fEITER system, two reconstruction algorithms, one accounting for movement and the other not, are compared. The corrections demonstrate that better spatial resolution and contrast of the lungs is obtained when accounting for electrode movement, as well as a reduction in boundary artefacts.
