Embodiment Construction

[0024] The chest cavity contour data acquisition method for human chest cavity electrical impedance tomography of the present invention is described in conjunction with the accompanying drawings:

[0025] The chest cavity contour data acquisition device adopted in the present invention for human chest cavity electrical impedance tomography, such as figure 1 As shown, the data acquisition device includes a displacement measurement sensor 1 , a bracket 2 , a support panel 3 and a load-bearing beam 4 and other parts. The displacement measurement sensor 1 is arranged on the support panel 3, through a number of via holes 3-5 on the support panel 3, the angle and position between it and the chest cavity of the human body can be adjusted arbitrarily, after the adjustment is completed, the via holes are passed through with screws 3-5 Fix the displacement measuring sensor 1 on the support panel 3 . The displacement measurement sensor 1 is used to measure the position information of th...

Abstract

The invention provides a thorax contour data acquisition method for human thorax electrical impedance tomography. An adopted device comprises multiple displacement measurement sensors (1), supports (2) and a supporting panel (3). Multiple via holes (3-5) are formed around a hole (3-4) of the supporting panel (3). Each displacement measurement sensor (1) is fixedly connected to the supporting panel (3) through at least two via holes (3-5). The included angles between the displacement measurement sensors (1) and the human thorax and the positions of the displacement measurement sensors (1) are adjusted according to different positions of the corresponding via holes (3-5). The measured human thorax is located at the proper measurement position by adjusting the height of the supports (2) and the width of gaps between all panel bodies of the supporting panel (3). Electrodes are evenly distributed on the surface of the human thorax by adjusting the positions of the displacement measurement sensors (1) and the included angles between the displacement measurement sensors (1) and the human thorax. Spatial position information needed for updating a field domain model can be acquired in real time.

Description

technical field [0001] The invention belongs to the technical field of bioelectrical impedance tomography, and in particular relates to a chest contour data acquisition method for human chest electric impedance tomography. Background technique [0002] Electrical Impedance Tomography (EIT) technology is a new type of non-invasive biomedical detection and imaging technology that takes the distribution or change of electrical impedance in the organism as the imaging target. It detects the voltage difference between electrodes To detect the impedance distribution inside the object to be measured, so as to reflect the biological characteristics of each biological tissue structurally and functionally. EIT technology is a new type of process detection technology, which has shown great application prospects in medical image-based diagnostic technology. Using EIT technology, it is possible to display the impedance distribution image of the tissue in the living body, the image of th...
