Dual-breast symmetry detection method for mammary electrical impedance scanning imaging

Abstract

The invention discloses a dual-breast symmetry detection method for mammary electrical impedance scanning imaging. The method comprises the steps of firstly, conducting standardization locating and zoning on the surfaces of the breasts, utilizing a mobile probe for completing whole-breast detection to obtain a series of detection data corresponding to detection zones according to the divided zonenumbers; furthermore, with the obtained detection data of different zones as the basis, fitting the data at the zone boundary to reconstruct full-breast impedance distribution information of the one-sided breast; finally, based on the full-breast impedance distribution information of the two-sided breasts, utilizing a similarity measurement method for conducting feature analysis on the symmetry zone. According to the method, the idea of dual-breast symmetry analysis is introduced into the mammary electrical impedance scanning imaging technology, a zone symmetry feature analysis method for dual-breast electrical impedance distribution is built, auxiliary distinguishing information can be provided for examination of the mammary electrical impedance scanning imaging technology, and the diagnosis accuracy rate is increased.

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.
