Device and method for determining axial position of electrode device for electrical impedance tomography

A device (1) for electrical impedance tomography (30) is configured to determine a situation with an axial shift of the electrode device on a thorax (34) of a human and to provide a control signal (79), which indicates the situation with axial shift of the electrode device. An electrical impedance tomography device (1) includes an electrode device, including a plurality of electrodes (33) arrangedspaced apart from one another, a signal feed unit (51), a signal acquisition unit (50), and a calculation and control unit (70) The calculation and control unit (70) may be configured as a central unit or an array of distributed units (cloud computing) in order to determine and to provide the axial shift. 种用于电阻抗断层成像（30）的设备（1）被设计为确定具有在人类生物的胸腔（34）上的电极装置的轴向移位的情况并且提供控制信号（79），所述控制信号表明具有所述电极装置的轴向移位的情况，所述设备具有带有彼此间隔开地布置的大量电极（33）的电极装置、信号馈入单元（51）和信号检测单元（50）、计算和控制单元（70）。所述计算和控制单元（70）可以被构造为中央单元或者被构造为分散的单元的装置（云计算），以便确定并且提供轴向移位。
