Abstract：
Microwave radiometry (MWR) is instrumental in detecting thermal variations in skin tissue before anatomical changes occur, proving particularly beneficial in the early diagnosis of cancer and inflammation. This study concisely traces the evolution of microwave radiometers within the medical sector. By analyzing a plethora of pertinent studies and contrasting their strengths, weaknesses, and performance metrics, this research identifies the primary factors limiting temperature measurement accuracy. The review establishes the critical technologies necessary to overcome these limitations, examines the current state and prospective advancements of each technology, and proposes comprehensive implementation strategies. The discussion elucidates that the precise measurement of human surface and subcutaneous tissue temperatures using an MWR system is a complex challenge, necessitating an integration of antenna directionality for temperature measurement, radiometer error correction, hardware configuration, and the calibration and precision of a multilayer tissue forward and inversion method. This study delves into the pivotal technologies for non-invasive human tissue temperature monitoring in the microwave frequency range, offering an effective approach for the precise assessment of human epidermal and subcutaneous temperatures, and develops a non-contact microwave protocol for gauging subcutaneous tissue temperature distribution. It is anticipated that mass-produced measurement systems will deliver substantial economic and societal benefits.
摘要：
微波辐射（MWR）有助于在解剖变化发生之前检测皮肤组织的热变化，证明对癌症和炎症的早期诊断特别有益。这项研究简洁地追踪了医疗领域微波辐射计的发展。通过分析大量相关研究并对比它们的优势，弱点,和性能指标，这项研究确定了限制温度测量精度的主要因素。审查确定了克服这些限制所需的关键技术，检查每种技术的现状和未来进展，并提出了综合实施策略。讨论阐明，使用MWR系统精确测量人体表面和皮下组织温度是一个复杂的挑战，需要集成天线方向性以进行温度测量，辐射计误差校正，硬件配置,以及多层组织正演和反演方法的标定和精度。本研究深入研究了微波频率范围内无创人体组织温度监测的关键技术,为精确评估人类表皮和皮下温度提供了有效的方法，并开发了用于测量皮下组织温度分布的非接触式微波协议。预计批量生产的测量系统将带来巨大的经济和社会效益。
