Background
At present, 1/2 women all suffer from different degrees of breast disease, with life threatening primarily breast cancer. In recent years, with the westernization of the life style of Chinese people, the increasing mental stress and the faster and faster life rhythm, the breast cancer gradually becomes an 'adventure' threatening the life safety of women. Early detection is one of the most effective means for treating breast cancer, and if the focus is found early enough, the cure rate of breast cancer is very high. For this reason, many women are each year admitted to hospitals for regular or irregular mammograms and other related medical examinations. However, such a detection means may cause many discomfort of the person to be detected, and therefore, the popularization and application of such a detection means are greatly hindered, and on the other hand, methods such as a molecular mammography technique, a magnetic resonance imaging spectrum, a minimally invasive image, a near infrared scan, and the like, which are used in professional detection of breast diseases in hospitals, are highly restricted by places and locations, and further, the purpose of finding breast diseases at first time cannot be achieved.
Therefore, a portable scheme capable of detecting breast diseases at the first time is urgently needed to be provided so as to meet the long-lasting self-help physical examination requirement of women.
For example, chinese patent CN 105212927 a discloses an intelligent corsage for detecting and evaluating the early risk of breast cancer. The invention comprises an inner layer cup, a middle air bag layer and an outer chest coating layer. Electrode arrays are symmetrically distributed on the inner layer cup and directly contact with mammary tissue; the electrode array comprises six electrodes which are distributed in a circular shape and a common electrode positioned at the circle center, the common electrode is grounded, and the other six electrodes are connected with the circuit control module. The circuit control module is used for forming an RLC circuit by equivalently connecting mammary tissues into an RC circuit and then connecting a matching inductor in series; by means of current excitation, the RLC circuit resonates at a certain frequency, and the resonant frequency is obtained from the corresponding and lowest voltage measured, and finally the condition of the breast of the user is determined. The invention not only has convenient, simple and safe detection and no harm to human body, but also can detect whether the breast tissue is diseased or not as soon as possible, and prevent and cure the breast disease in an early stage. However, the technical scheme disclosed by the invention adopts an electrical impedance frequency sweep frequency detection method of resonance frequency, and the method is adopted for detection by utilizing the symmetry of normal mammary tissue of a human body and the resonance principle in a circuit, so that a plurality of discomfort of a detected person can be caused, some side effects are generated, and the human health is injured.
For another example, chinese patent CN 103705215 a discloses an intelligent corsage for detecting breast diseases, which is provided with a signal acquisition module, a wireless communication module and a control module connected in sequence; the signal acquisition module comprises an infrared transmitter, an infrared receiver and a signal processor which are sequentially connected, and the signal processor is connected with the wireless communication module; the control module comprises a microprocessor, a memory and a buzzer, the microprocessor is respectively connected with the memory and the buzzer, and the microprocessor is connected with the wireless communication module. The invention judges the abnormality of the mammary gland by collecting the near infrared ray gray scale signal of the mammary gland tissue, has high reliability compared with the self-check of women by a specific method and the periodic physical examination every year, can find the abnormality of the mammary gland in time, and simultaneously adopts the wireless communication module in the corset to reduce electronic circuits in the corset and increase the comfort level of the corset. However, various interference factors must be doped in the infrared signal received by the infrared receiver, and therefore, a high error must exist in the received feedback signal, thereby affecting the accuracy of the detection result.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Electromagnetic waves longer than 0.78 μm are outside the red color of the visible spectrum and are called infrared or infrared radiation, with wavelengths in the range of 0.78-1000 μm. In nature, all objects can radiate infrared rays, so that infrared images formed by different thermal infrared rays can be obtained by measuring the infrared ray difference between a target and a background by using a detector.
The photothermographic image of the target is different from the visible image of the target, which is not a visible image visible to the human eye, but rather an image of the radiation intensity distribution of the surface electromagnetic spectrum. Infrared thermography renders the surface photothermal gradient profile invisible to the human eye directly, converting it into a visible image representing the target surface photothermal intensity profile. All objects with a temperature above absolute zero (-273 c) will emit thermal infrared rays continuously. Infrared (or infrared radiation) is the most widely occurring radiation in nature, and it also has an important characteristic: the magnitude of the infrared radiation energy of the object is directly closely related to the temperature value of the surface of the object and corresponds to the temperature value of the surface of the object one by one. The infrared radiation can be used for measuring the electromagnetic photo-thermal intensity and analyzing the thermal state of an object, thereby providing an important detection means and a diagnosis tool for industrial production, energy conservation, environmental protection, medical care and the like.
Infrared thermal imaging has already entered clinical research and application in hospitals at present, and can be used as a diagnosis basis in various fields such as head, neck, cardiovascular system, lung, breast, gastrointestinal system, liver, gallbladder, prostate, spine, four limbs blood vessels and the like, and can comprehensively perform early warning analysis on various diseases of the whole body. The human body is a natural biological infrared radiation source which can continuously emit and absorb infrared radiation to the surroundings through analysis of the principle of physics, the temperature distribution of the normal human body has certain stability and characteristics, the temperatures of all parts of the body are different, different thermal fields are formed, when a disease or function change occurs at a certain part of the human body, the blood flow at the part can correspondingly change, the local temperature of the human body is changed, and the local temperature is shown to be higher or lower. According to the principle, the infrared radiation of the human body is collected by a thermal imaging system and converted into digital signals to form a color heat map, and the heat map is analyzed by professional doctors by utilizing special analysis software to judge the parts of the focus of the human body, the nature of diseases and the degree of pathological changes, thereby providing reliable basis for clinical diagnosis.
