Poster: Fast Electrical Impedance Tomography for Non-Invasive Medical Imaging
Non-linear Electrical Impedance Tomography (EIT) is a novel technique for non-invasive and cost-effective imaging of internal structures of the human body. EIT tries to reconstruct the differing electrical conductivities within the body from current injection and voltage measurements through skin electrodes. This method provides images which cannot be obtained by other imaging methods and is also much more harmless. The solution of this ill-posed Inverse Problem involves the inversion of a simplified set of Maxwell's Equations on the domain under investigation. This can be achieved efficiently with todays computer power when certain conditions are met. We have developed an algorithm, which reduces the number of finite elements required in the reconstruction process. This results in faster convergence of the solution at higher accuracy compared to conventionally applied techniques. We demonstrate how the gained speed-up in the image formation process enhances the potential use of EIT in medical real-time imaging.

Abstract
Non-linear Electrical Impedance Tomography (EIT) is a novel technique for non-invasive and cost-effective imaging of internal structures of the human body. EIT tries to reconstruct the differing electrical conductivities within the body from current injection and voltage measurements through skin electrodes. This method provides images which cannot be obtained by other imaging methods and is also much more harmless. The solution of this ill-posed Inverse Problem involves the inversion of a simplified set of Maxwell's Equations on the domain under investigation. This can be achieved efficiently with todays computer power when certain conditions are met. We have developed an algorithm, which reduces the number of finite elements required in the reconstruction process. This results in faster convergence of the solution at higher accuracy compared to conventionally applied techniques. We demonstrate how the gained speed-up in the image formation process enhances the potential use of EIT in medical real-time imaging.
