Abstract
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.
