Abstract
Electrical Impedance Tomography (EIT) applies and measures elec-
trical energy on the boundary of a medium to produce an image of its
internal impedance distribution. In many medical applications, such
as imaging of the chest, the electrodes move during measurements, in-
troducting artefacts into the calculated images. This paper proposes
a new algorithm that compensates for electrode movement during dif-
ference EIT measurements. The reconstructed image is calculated by
