Detection array structure and detection method of breast elastography based on piezoelectric impedance method

Abstract

The invention discloses a mammary tissue elastography detection array structure based on a piezoelectric impedance method and a detection method of the mammary tissue elastography detection array structure. The detection array structure is characterized in that multiple piezoelectric unit structures are arranged on the internal surface of a supporting frame to form a shape similar to the surface of a breast, and can be worn on the to-be-detected breast of a human body; based on the piezoelectric impedance method, the analysis relationship between the resonance frequency of the piezoelectric unit structures and the elastic information of a to-be-detected sample is obtained by measuring the resonance frequency of piezoelectric parameters such as the admittances and the phases of the piezoelectric unit structures and according to an established corresponding piezoelectric equivalent circuit model. According to the detection method provided by the invention, the specificity is strong; a quantitative detection result can be given; therefore the structure and the method are more applicable for the detection of the breast cancer that a cancer tissue is located in the superficial zone, and the difficult problem that the detection on the superficial tissue is difficultly realized through ultrasonic elastography is solved; the structure and the method are simple and reliable; not only can assistance be provided for the implementation of physical examination by medical workers, but also the daily physical examination in a family can be realized, so the early discovery and the early treatment of related breast diseases can be favourably realized.

Description

technical field [0001] The invention belongs to the field of medical health detection, and in particular relates to a breast elastography detection array structure and detection method based on piezoelectric impedance method. Background technique [0002] The mammary gland is one of the most important organs of the human body, but the incidence of mammary gland-related diseases has remained high. Such diseases have had a significant impact on the normal production and life of residents, and they need to be given enough attention. Among these breast-related diseases, breast cancer is a malignant disease that needs to be focused on. It should be pointed out that although the current living standards and medical conditions are improving, the incidence of breast cancer continues to rise and has always been high. death rate. [0003] At present, the means used for this kind of malignant disease is the policy of early detection and early treatment, but there are still challenges ...

AI Technical Summary

Problems solved by technology

However, the cancerous tissue of breast cancer is located in the superficial layer, and ultrasound elastography and other techniques are difficult to accurately detect breast cancer tissue due to the near-field effect. Therefore, it is urgent to propose an elastography method suitable for breast cancer.
