Design method of wearable microwave detecting antenna and antenna array based on medical images

Abstract

The invention discloses a design method of a wearable microwave detecting antenna and an antenna array based on medical images. Medical requirement information is extracted according to the obtained medical images of the body part to be detected, and the wearable microwave detecting antenna and the antenna array are designed. The information extracted from nuclear magnetic resonance images includes but is not limited to the distribution of various kinds of tissue and the position and size of a detection target; the information extracted from three-dimensional scanned images includes but is notlimited to the shape and size of a human body surface area. According to the extracted information, the optimal path and detection frequency of microwave detection and the position and size of a placement area of the wearable microwave antenna and the antenna array are determined. Screening is conducted in a pre-designed antenna library, a user selects and optimizes screening results according topersonal preferences, and a solution for manufacturing the wearable antenna and the antenna array is generated. In this way, the wearable microwave detecting antenna and the antenna array which meetthe function and size requirements of individual characteristics of the user and satisfy the preference of the user can be designed.

Description

technical field [0001] The invention belongs to the technical field of biomedical detection, and in particular relates to a design method of a wearable microwave detection antenna and an antenna array. Background technique [0002] At present, the commonly used biomedical detection methods include X-ray photography, computed tomography and nuclear magnetic resonance technology, etc., but the above methods all have certain defects, such as radiation damage to the human body, high cost, and large space occupation. Compared with the above technologies, microwave detection has unique advantages, such as low radiation, millimeter-level positioning and low detection cost, and microwave sensors can be integrated into wearable devices to provide long-term and real-time human detection. The principle of microwave detection of the human body lies in the different absorption, reflection and diffraction properties of different biological tissues and electromagnetic waves, so as to disti...
