An electrical impedance tomography system for determining electric properties of an internal body part of a patient comprises an electrode array in electrical contact with the patient, a device for applying current or voltage between electrodes of the array and for measuring voltages or currents between other combinations of the array A computing unit comprises a processor and a storage unit. The storage unit comprises a reconstruction algorithm used by the data processor for reconstructing the measured voltages of the body part into electrical properties or changes thereof. The data processor outputs a representation of the reconstructed electrical properties and generates or processes anatomical models descriptive of the body part The data processor uses biometric data of the patient and, according to the biometric data of the patient, selects an anatomical model for reconstructing the measured electrical voltages of the body part into electrical properties or changes thereof.

Electrical impedance tomography system

An electro impedance measuring belt for placing electrodes around the thorax of a patient comprises an array of a plurality of spaced apart electrodes, and a support structure, on which the electrodes are arranged. The support structure with the electrode array comprises two angulated legs on which the electrodes are lined up, the two legs spread out from an apex at an angle, such that, when the belt is put around the thorax of a patient, the array of electrodes extends from the back of the patient, where the apex of fee angulated legs is to be located, essentially parallel to the ribs to the lower part of the breastbone of the patient.
