Abstract

A focus detection electrode system for electrical impedance tomography, comprising a focus detection electrode unit (1), a flexible connecting piece (2) and an electrode connecting wire group (3); the focus detection electrode unit (1) is not less than two . The focusing detection electrode unit (1) has a middle flexible electrode (4), and flexible electrodes (5, 6) are arranged above and below the middle flexible electrode (4), and the distances between the three upper flexible electrodes are equal. The middle flexible electrode (4), the upper flexible electrode (5) and the lower flexible electrode (6) are connected by an insulating flexible material (7); the flexible electrode is in direct contact with the surface of the detection object; The wired connection port (8) is used to connect with the electrode connection line group (3); the upper and lower flexible electrodes (5, 6) are connected to two adjacent focus detection through the flexible connection sheets (2) on the left and right sides The electrode units (1) are connected together to form a strip-shaped detection electrode array.

Description

technical field [0001] The present invention relates to a focused detection electrode system for electrical impedance tomography. Background technique [0002] Electrical Impedance Tomography (EIT) is based on the fact that different tissues in the human body have different electrical conductivities under different physiological and pathological conditions, and various methods are used to apply a small safe excitation current to the human body to measure the potential of the corresponding body surface. Information, techniques for reconstructing images of the resistivity distribution inside the human body or its changes. In addition to providing information on the anatomical structure of human tissues, EIT technology can also provide functional information about human physiological and pathological states. It is an ideal non-invasive medical imaging technology with great development potential. [0003] Medical electrical impedance imaging technology has broad prospects in th...
