SENSOR DEVICE FOR ELECTRICAL IMPEDANCE TOMOGRAPHY IMAGING, ELECTRICAL IMPEDANCE TOMOGRAPHY IMAGING INSTRUMENT AND ELECTRICAL IMPEDANCE TOMOGRAPHY METHOD

摘要

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.
