Classification: CPC A  G | IPC A  G

Claim 0:
1. A system for electrical impedance tomography of an object, said system comprising:
a plurality of electrodes configured to be attached to the object;
a plurality of impedance measurement units, wherein each impedance measurement unit is associated with two or more electrodes of the plurality of electrodes, and wherein each impedance measurement unit comprises a current generator for generating a stimulation current between the electrodes associated with the impedance measurement unit and an amplifier for amplifying a measurement voltage between the electrodes associated with the impedance measurement unit;
wherein the system is configured to perform a plurality of impedance measurements, wherein, for each impedance measurement, one impedance measurement unit among the plurality of impedance measurement units is set in a stimulation mode for providing a stimulation current into the object between the electrodes associated with the one impedance measurement unit, and wherein the impedance measurement unit being set in the stimulation mode is switched among the plurality of impedance measurement units between different measurements in the plurality of impedance measurements, and
wherein each impedance measurement unit is configured to be set in a calibration mode during at least one of the plurality of impedance measurements for calibration of the impedance measurement unit during electrical impedance tomography measurements.
