Description

technical field [0001] The present invention relates to the technical field of electrical impedance imaging, and in particular, to an electrical impedance imaging method, device, storage medium and electronic device. Background technique [0002] Electrical Impedance Tomography (EIT) is a non-radiation, non-invasive, low-cost, functional imaging technique. The basic principle of electrical impedance imaging is that according to different electrode arrangements, a variety of excitation methods are used to apply a safe current lower than the cell excitation threshold to the area to be measured, and then the voltage distribution data on the body surface is measured by scanning the array electrodes, and then An image of the human body to be measured is obtained based on the voltage distribution data. [0003] The impedance change exhibited by organisms or biological tissues, biological organs, and biological cells under the action of a safe current below the excitation threshol...
