Electrical impedance imaging system applied to chest detection

Abstract

The invention provides an electrical impedance imaging system applied to chest detection, which comprises a supporting seat and an electrode mechanism arranged on the supporting seat, the motor mechanism comprises a plurality of lifting assemblies which are arranged on the supporting seat and are arranged in a circumferential array, a driving assembly for controlling the lifting assemblies to get close to one another on the supporting seat, and electrodes arranged at the top ends of the lifting assemblies; the multiple electrodes are arranged at the top end of the lifting assembly through the mounting block, and the multiple electrodes are arranged on the mounting block at equal intervals; the mounting block is detachably connected with the lifting assembly; according to the invention, the electrodes can be uniformly and consistently placed on the chest of the measured target, so that the electrodes are fully contacted with the chest skin, and the imaging effect and the diagnosis result of the electrical impedance imaging system are ensured.

Description

technical field [0001] The invention relates to the technical field of electrical impedance imaging, in particular to an electrical impedance imaging system applied to chest detection. Background technique [0002] Because the electrical impedance characteristics of diseased tissue and normal biological tissue are significantly different, medical imaging techniques using the principle of bioimpedance, such as electrical impedance tomography (Electrical Impedance Tomography, EIT), electrical impedance spectroscopy (Electrical Impedance Spectroscopy, EIS), It can effectively detect and locate the diseased part of the organism. The medical imaging technology using the principle of bioimpedance detects the impedance distribution inside the organism by placing electrodes on the surface of the organism and injecting low-frequency low-power current, and detecting the voltage difference between the electrodes to detect the impedance distribution inside the organism. It can be detec...

Problems solved by technology

[0003] Since the electrical impedance imaging technology is to place multiple electrodes in a certain arrangement to ensure the quality of the image, the placement of electrodes for different test targets must conform to a uniform pattern, so if the electrodes are directly placed on the surface of the test target by the operator, it is very difficult Difficulty in ensuring electrode arrangement consistent with pre-planned patterns, uniformity and consistency across different test targets, negatively impacting image quality and requiring significant time-consuming draining of electrodes before each test

[0004] Due to differences in the gender of the test target individual, it often occurs that the skin of the test chest cannot fully contact with some electrodes, or even gaps appear, resulting in some electrodes not in contact with the skin of the test chest, and some electrodes are not in good contact with the skin, resulting in electrode Some electrodes in the array cannot provide corresponding real electrical signals, which will inevitably affect the imaging effect and diagnostic results of the electrical impedance imaging system
