A new imaging technique, Electrical Impedance Tomography (EIT), will soon be used to monitor important bodily functions. A collaborative project between TU Wien, the Medical University of Vienna and the University of Veterinary Medicine Vienna, has enabled significant progress to be made with this technology. It couldn't be simpler, more convenient or cheaper: with electrical impedance tomography, a belt featuring electrodes is applied directly to the skin. Minuscule currents are passed through the body and the resulting electrical voltage is measured; these measurements are then used to produce images of various bodily functions. This enables lung function, for example, to be continuously monitored during artificial respiration. There is, however, as yet no standardised method for converting the measured data into reliable images. But now a project between TU Wien, the Medical University of Vienna and the University of Veterinary Medicine Vienna has succeeded in showing that the quality of the results drastically improves when the evaluation methods are individually tailored for each patient.
