SENSOR DEVICE FOR ELECTRICAL IMPEDANCE TOMOGRAPHY IMAGING, ELECTRICAL IMPEDANCE TOMOGRAPHY IMAGING INTRUMENT AND ELECTRICAL IMPEANCE TOMOGRAPHY METHOD

摘要

Sensor device for EIT imaging comprising an electrode array for measuring an impedance distribution, characterized in that at least one sensor for determining spatial orientation of the electrode array is coupled to the electrode array. EIT imaging instrument 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, characterized in that 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. EIT imaging method for measuring an impedance distribution and adjusting said measured impedance distribution comprising the steps of measuring impedance distribution by using an impedance distribution measuring device comprising an electrode array, and transforming the measured impedance distribution into EIT images, characterized in that gravitational influences are determined by measuring the spatial orientation of a test subject, and values of the measured impedance distribution are adjusted according to said spatial orientation in order to account for gravitational influences.
