Abstract

A system for electrical impedance tomography comprises: a plurality of electrodes (110); a plurality of impedance measurement units (120), each being associated with two or more electrodes (110), and wherein each impedance measurement unit (120) comprises a current generator (122) for generating a stimulation current between the electrodes (110) and an amplifier (132; 134) for amplifying a measurement voltage between the electrodes (110); wherein the system (100) is configured to perform a plurality of impedance measurements, wherein, for each impedance measurement, one impedance measurement unit (120c) is set in a stimulation mode for providing a stimulation current into the object, and wherein the impedance measurement unit being set in the stimulation mode is switched among the plurality of impedance measurement units (120), and wherein each impedance measurement unit (120) is configured to be set in a calibration mode during at least one of the plurality of impedance measurements.
