Electrode sheet and electrode belt with quasi-periodic concave-convex liquid-holding structure

Abstract

The electrode sheet and the electrode belt with a quasi-periodic concave-convex liquid-holding structure provided by the invention belong to the technical field of electrical impedance tomography. The electrode sheet includes: an electrode sheet body with a working surface for fitting the human body; Liquid structure, including several liquid-holding grooves opened on the working surface, the liquid-holding grooves are used to fill the matching medium, several liquid-holding grooves are arranged symmetrically on the central axis on the working surface, and the groove depths of several liquid-holding grooves are the same . Due to the quasi-periodic quasi-periodic concave-convex liquid-holding structure on the working surface of the electrode sheet, the potential distribution on the surface of the electrode sheet can be more uniform and the modeling error can be reduced; in addition, the quasi-periodic concave-convex liquid-holding structure can be used for To accommodate the matching medium, when the electrode sheet moves, it can also ensure that there is enough matching medium on the working surface of the electrode sheet, so that the electrode sheet is in good contact with the surface of the human body, thereby improving the application effect of the matching medium.

Description

technical field [0001] The invention belongs to the technical field of biomedical electrical impedance imaging, and more specifically relates to an electrode sheet and an electrode belt with a quasi-periodic concave-convex liquid-holding structure. Background technique [0002] Electrical impedance tomography (Electrical Impedance Tomography, EIT) is a non-invasive biomedical imaging technique aimed at detecting the distribution of electrical impedance in living organisms or monitoring its short-term changes. In this method, a safe excitation current is applied on the surface of the biological tissue under test by the excitation electrode, and the voltage data of other parts are detected by the measurement electrode, and the image inversion algorithm is used to reconstruct the electrical impedance distribution or its short-term change inside the tissue under test. These medical image information can reflect the internal structure of the tested tissue and its organ function i...
