Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings, and embodiments of the present invention will be given.

[0027] This microwave near-field medical body detection method is characterized in that: using finite element confocal imaging method to extract correlation information between direct wave and scattered wave through time domain difference method, performing finite element segmentation on the imaging area, and then calculating each According to the time delay from each antenna to each grid, a grid group conforming to the three-dimensional trajectory surface equation is obtained. According to the superposition of the grid group after the intersection of multiple trajectories, the position of the early breast tumor is determined.

[0028] Its main steps are:

[0029] A. Initial setting of parameters and imaging area: set the monitoring breast radius R according to the individual; the number of scans N and the number ...

Abstract

The invention relates to a testing method of microwave near-field medical body, which is characterized in that through a difference time-domain method, relevant information between direct wave and scattered wave is extracted by the use of a finite element confocal imaging method to process the finite element segmentation of an imaging region, and then time delay from each antenna to each grid is calculated to obtain a grid group accords with a three-dimensional trajectory surface equation. According to the superposition of the grid group after the intersection of a plurality of trajectories, the position of early breast tumor of the female is determined. Compared with commonly used X ray, CT or nuclear magnetic resonance (NMR) at present, the testing method of microwave near-field medical volume proposed by the technical proposal can reliably determine the three-dimensional spatial location of the early breast tumor of the female and also cause much less damage to human bodies.

Description

technical field [0001] The invention relates to a microwave near-field medical detection method and an application thereof, belonging to the category of medical microwave near-field medical detection methods. Background technique [0002] Breast tumor is a common malignant tumor that endangers women's health. Since the late 1970s, its incidence rate has been ranking first among female tumors, and it has been increasing at a rate of 2% per year. At present, about 1.5 million women in the world suffer from breast cancer every year, and more than 500,000 women die of breast cancer. In recent years, the incidence of breast cancer in my country is also on the rise. The age of onset begins to increase after the age of 30, and reaches a peak at the age of 40 to 49, which seriously threatens the lives and health of women. [0003] At the same time, it has also been reported that if breast tumors can be detected in time when the top diameter is less than 10mm (that is, in the early ...
