Research Status Regarding to Inhibiting Electrode Perturbation Caused Artefacts in Electrical Impedance Tomography
摘要
Abstract
Electrical impedance tomography imaging has been widely applied in medical field, such as lung function, early detection of breast cance, brain function imaging and so on. In the process of imaging, the variation of the electrode on the boundary of the measuring object will cause the error of model parameter in the electrical impedance imaging algorithm, resulting in a large number of artifacts in the reconstructed image. To solve this problem, firstly, this paper summarized several algorithms to improve the noise interference, and gave a brief introduction to the physical basis of these algorithms. Then, the principle and characteristics of the current several anti-electrode position change interference were summarized. At the end of the paper, the algorithms were analyzed and the future research and application of those algorithms were prospected.关键词
