【摘要】：乳腺癌是女性中发病率最高的恶性肿瘤,并且乳腺癌患者趋于年轻化。调查数据表明,首次经医院检查确诊已病变为乳腺癌的患者中有大约63.6%处于中晚期,导致治疗延误,影响乳腺癌患者的存活率。目前,早发现、早诊断、早治疗的“三早”治疗手段被公认为乳腺癌治疗最有效的方法,且相关领域的专家也建议女性应坚持每月做一次乳房自我检查。然而日常自查对于普通女性来说,由于缺乏专业知识,存在较大的不确定性,难以达到预期效果,仍需有效的仪器检测。但现有的钼靶、超声、MRI等检测方法不仅存在对人体有害或费用昂贵等不足,而且均需要去医院就诊,并不适合日常自查。因此,开发一套可以协助女性自查的便携设备是有必要的。本研究内容更针对这一问题,基于共振频率的电阻抗频谱(REIS)技术,设计并开发了一款用于乳腺癌早期风险监测的可穿戴系统。前期我们已经完成基于REIS技术的乳腺癌临床检测仪器,并在临床测试中取得了良好的效果。本文面向REIS技术的可穿戴式应用进行了设计,实现乳腺癌早期风险监测的可穿戴系统。系统主要分为智能胸衣、移动终端、云服务器三个部分。智能胸衣是系统的检测部分,内部集成了电极传感器,利用REIS技术原理采集乳房的阻抗数据。移动终端是系统的人机交互部分,不仅可以连接控制智能胸衣;还拥有可以提示相关信息,反映当前测量状态的界面;更能上传测量数据。云服务器是系统的后台服务部分,可以为用户提供风险值计算和数据存储服务,保存用户每次的测量数据。经过不断的调试与优化,本文研究开发的系统基本实现了预期目标,完成了各部分的功能。智能胸衣可以很好地采集到乳腺数据,并传输给手机;移动终端使用简单、清晰、明了,可以连接胸衣和服务器,显示并控制整个测量流程;云服务器实时监听客户端的请求,接受并存储用户数据,计算并返回风险值。调试过程中,系统先后进行了模拟测试和实体测试,验证胸衣的数据采集功能。模拟测试中,系统重复测试稳定的物理电容,发现每次测的共振频率误差均未超过2%,系统稳定性良好。在医院初步的实体测试中,测量的乳房数据对被测对象的异常情况有明显反应。本文最后就系统实现可穿戴存在的问题和解决方案进行了分析,为系统进一步优化明确了方向,使系统可以更快地推广应用,协助女性自查,为系统在乳腺癌早期风险监测中发挥作用奠定了基础。
[Abstract]:Breast cancer has the highest incidence of malignant tumors among women, and breast cancer patients tend to be younger. Survey data show that about 63.6% of the patients who have been diagnosed with breast cancer for the first time after hospital examination are in advanced stages, leading to delays in treatment. Affects the survival rate of breast cancer patients. At present, early detection, early diagnosis and early treatment are recognized as the most effective methods for breast cancer treatment. Experts in related fields also suggest that women should do breast self-examination once a month. However, for ordinary women, due to lack of professional knowledge and greater uncertainty, it is difficult to achieve the desired results. But the existing methods, such as molybdenum target, ultrasonic MRI and so on, are not only harmful to human body or expensive, but also need to go to hospital, so they are not suitable for daily self-examination. It is necessary to develop a portable device that can assist women in self-examination. A wearable system for early breast cancer risk monitoring has been designed and developed. The wearable application of REIS technology is designed to realize the wearable system of early breast cancer risk monitoring. The system is mainly divided into intelligent corset, mobile terminal, and so on. The intelligent corset is the detection part of the system, the electrode sensor is integrated inside, and the impedance data of the breast is collected by using the principle of REIS. The mobile terminal is the human-computer interaction part of the system. Not only can you connect and control the smart bra, but you also have an interface that prompts information about the current measurement status, and uploads measurement data. The cloud server is the backstage service of the system. It can provide users with risk value calculation and data storage services, and save the measured data of users every time. After continuous debugging and optimization, the system studied and developed in this paper has basically achieved the expected goals. The smart corset can collect breast data and transmit to the mobile phone, the mobile terminal is simple, clear and clear, it can connect the corset and server, and display and control the whole measurement process. The cloud server listens to the client's request in real time, accepts and stores the user's data, calculates and returns the risk value. During the debugging process, the system successively carries on the simulation test and the entity test, verifies the corset's data collection function. The system repeatedly tested the stable physical capacitance and found that the resonance frequency error of each measurement was not more than 2 and the system was stable. The measured breast data have obvious response to the abnormal situation of the object under test. Finally, this paper analyzes the problems and solutions to the wearability of the system, and defines the direction for further optimization of the system. The system can be popularized and applied more quickly, and it can help women to check themselves. It lays the foundation for the system to play a role in early breast cancer risk monitoring.
