Abstract: A sensor device for EIT imaging comprises an electrode array for measuring an impedance distribution, with at least one sensor for determining spatial orientation of the electrode array coupled to the electrode array. An EIT imaging instrument is connectable to a sensor for determining spatial orientation of a test person, and optionally in addition connectable to a sensor for gathering information on electrical and/or acoustic activity and/or a sensor for gathering information on dilation. A computing device is connected or integrated for adjusting impedance data based on spatial data, which spatial data describe the spatial orientation of a test subject. An EIT imaging method for measuring an impedance distribution and adjusting said measured impedance distribution comprises measuring impedance distribution by using an impedance distribution measuring device comprising an electrode array, and transforming the measured impedance distribution into EIT images.

Abstract: 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.
