A double-breast symmetry detection method based on breast electrical impedance scanning imaging

Abstract

The invention discloses a double-breast symmetry detection method for breast electrical impedance scanning imaging. Firstly, standardized positioning and area division are carried out on the surface of the breast, and according to the divided area numbers, the mobile probe completes the whole breast detection to obtain the corresponding detection area. A series of detection data; further based on the measurement data obtained in different areas, by fitting the data at the boundary of the area, reconstruct the whole-breast impedance distribution information of one breast; finally, based on the whole-breast impedance distribution information of both breasts , using the method of similarity measure to analyze the characteristics of the symmetry region. This method introduces the idea of ​​double-breast symmetry analysis into breast electrical impedance scanning imaging technology, and establishes a regional symmetry feature analysis method for double-breast electrical impedance distribution, which can provide auxiliary discriminant information for breast electrical impedance scanning imaging technology inspection and improve diagnosis. Accuracy.

Description

technical field [0001] The invention relates to a method for detecting mammary gland electrical impedance, in particular to a method for detecting double breast symmetry in mammary gland electrical impedance scanning imaging. Background technique [0002] The breast is a symmetrical organ of the human body. In clinical breast health examinations (such as palpation, mammography, etc.), the symmetry analysis of the anatomical structure and physiological characteristics of bilateral breast tissues is often used to assist in the judgment of breast diseases, so as to improve the judgment the accuracy rate. [0003] Electrical Impedance Scanning (EIS) uses the principle of the difference between the electrical impedance characteristics of diseased tissue and normal tissue, and obtains the distribution characteristics of tissue electrical impedance under the detection probe to judge the health of the tissue in the detection probe area. The operator can check the health of the whol...

AI Technical Summary

Problems solved by technology

[0004] 1) The image collected by the probe in a single time is the local tissue state information of the breast (under the probe coverage area), and the impedance distribution information of the whole breast cannot be directly obtained, which is not conducive to the comparative analysis of the symmetrical characteristics of the two breasts;

[0005] 2) To move the probe by hand, it is necessary to accurately locate the detection probe to the symmetrical area of ​​the contralateral breast, which requires high operating experience and is difficult

However, the hand-held probe detection method adopted by EIS cannot intuitively obtain the impedance state information of the whole breast tissue, and is not conducive to the comparison detection of double breast symmetry.
