| description | The invention discloses a method for judging the position of an electrode for lung electrical impedance imaging in spontaneous respiration in the technical field of medical imaging, which comprises the following steps: step 1, data acquisition: enabling a to-be-detected object to perform spontaneous respiration, and recording electrical impedance data, body temperature data and pulmonary ventilation data of the to-be-detected object; 2, data processing, wherein on the basis of the obtained electrical impedance data, the ventilatory capacity impedance ratio of different breaths is calculated in combination with lung ventilation data; 3, position judgment, wherein the positions of the electrodes are judged on the basis of the ventilatory capacity impedance ratios of different breaths; and 4, verifying and adjusting: judging whether the electrode position is accurate or not through actual measurement and simulation verification, and comparing imaging effects and data quality under different electrode positions. |
