| Abstract: | Abstract In this paper, a movable electrical impedance tomography (MEIT) system is introduced to reduce the noise of electrical impedance tomography. This moving scheme could yield more independent measurements and reconstruct improved impedance images. After averaging the entire reconstructed image, we could improve the image quality substantially. The experiment result shows a quality improvement compared with the measuring systems without moving scheme. This preliminary work provides a feasibility to reduce the noise of electrical impedance tomography by a moving electrode scheme. |
