In the present embodiment, when the electrical impedance imaging apparatus 2 is detected by the detection system 1000, the parameters of the electrical impedance imaging apparatus 2 are initially calibrated. Parameters calibrated by the electrical impedance imaging apparatus 2 include, but are not limited to, the intensity of the acquired electrical signal, the amplification level, and the like.
After calibration, the graphic pieces 32 with different shapes are selected to be fixed on the transmission rod 313 for detection, and different speed modes can be set in the control piece 311 according to actual detection conditions. Different graphic elements 32 may be replaced during the inspection process to improve the accuracy of the inspection data.
During detection, the electrical impedance imaging device 2 forms a corresponding test image according to the electrical signals transmitted by the lead 23, and transmits the test image to the comparison device 3.
The comparison device 3 receives the test image and judges whether the initial calibration and imaging effect of the electrical impedance imaging device 2 are qualified or not according to the preset image and the test image. Specifically, the comparison device 3 adopts program comparison, and is connected with the electrical impedance imaging device 2 to access data acquired by the electrical impedance imaging device 2, so that the data is directly compared with a preset image, and the data detection is more accurate and convenient.
In the embodiment, the detection conditions, namely the concentration of the brine and the shape of the graphic piece, can be changed quickly in the detection process, so that the method is convenient and quick. At the same time, the image response speed of the electrical impedance imaging device can be observed. The comparison equipment can be used for rapidly comparing the imaging effect, and the actual dynamic imaging effect of the electrical impedance imaging equipment can be judged more accurately and rapidly through the comparison equipment.
