Electro-impedance tomography device and method

摘要

The electrical impedance tomography-apparatus has multiple electrodes (4) which are attached around the chest of a patient, and a control- and evaluating unit which is set to provide a pair of electrodes as applied pair of electrodes with an alternating current or with an alternating voltage. The control- and evaluating unit is provided to determine a time series of the global ventilation course from the sequence of reconstructed matrices as a time series of the average impedance change or as a time series of a measured ventilation volume. An independent claim is included for a method for receiving a sequence of electrical impedance tomography-images of a cross-sectional plane of the chest of a patient by the electrodes.
