Embodiment Construction

[0028] The drawings are for illustration only and should not be construed as limiting the invention. The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] figure 1 is a schematic flowchart of a method 100 for generating a three-dimensional blood perfusion image based on electrical impedance imaging according to an embodiment of the present invention.

[0030] figure 1 The method 100 begins at step 110, where an electrical impedance signal of a human body is measured. Specifically, the electrode array distributed in the three-dimensional space is used to measure the electrical impedance of the area of ​​the human body to be measured to obtain electrical impedance measurement signals.

[0031] Electrical impedance measurements first require an array of electrodes to be fixed around the area of ​​the body to be measured. The electrode array includes several electrodes distribute...

Abstract

Provided are a method and device for generating a three-dimensional blood perfusion image based on electrical impedance imaging. The method (100) includes: using an electrode array distributed in a three-dimensional space to perform electrical impedance measurement on a human body area to be tested to obtain an electrical impedance measurement signal (110); based on a blood perfusion signal in the electrical impedance measurement signal, reconstructing The algorithm reconstructs a three-dimensional blood perfusion image (120). Thus, a three-dimensional image of the electrical impedance change caused by blood perfusion can be generated. Compared with the two-dimensional image of the prior art, it can more intuitively reflect the blood perfusion on a volume area in the three-dimensional space of the human body area, which is beneficial to image Analytical comparison, disease detection and diagnosis.

Description

technical field [0001] The present invention relates to electrical impedance imaging technology, and more particularly to a method and device for generating a three-dimensional blood perfusion image based on electrical impedance imaging. Background technique [0002] Electrical Impedance Tomography (EIT) is a non-invasive technique for reconstructing in vivo tissue images that targets the electrical resistivity distribution inside the human body or other organisms. The human body is a large bioelectrical conductor, and each tissue and organ has a certain impedance. When a local organ of the human body becomes diseased, the impedance of the local part must be different from that of other parts. Make a diagnosis. [0003] The electrical impedance imaging methods of the prior art can only reconstruct two-dimensional blood perfusion images. This two-dimensional image reflects the change of electrical impedance caused by blood perfusion in a section of the human body to be meas...
