A thesis on the use of electrical impedance tomography (EIT) for noninvasive patient monitoring argues for the development of an EIT device suitable for large-scale commercialisation. Completed by Pascal Olivier Gaggero at the Swiss private research centre CSEM and University of Neuchâtel, the thesis reportedly represents a significant step forward in the clinical use of EIT.
