As a non-invasive and non-radiative non-contact clinical detection technology, infrared thermography can identify various diseases early by detecting the body surface temperature and reconstructing the temperature distribution image, and achieve early diagnosis and intervention. This article focuses on reviewing the application and related research progress of infrared thermography in the fields of acute respiratory infectious diseases, sleep apnea syndrome, traditional Chinese medicine lung disease research, neonatal intensive care, and early screening of pulmonary embolism, which has important clinical guidance significance. As a Functional imaging technology, the core advantage of infrared imaging is "Early". Unlike structural changes in the course of a disease, the early stages of a disease are often Hemodynamics, the functional changes of local abnormal temperature distribution caused by local inflammation and so on can be early diagnosed, early intervention and dynamic monitoring by means of infrared thermography technology based on thermal sensitivity.

红外热成像作为一种具备无创性、无辐射性的非接触式临床检测技术，通过检测人体表面温度并重建温度分布图像，可以早期识别多种疾病，并实现早期诊断及干预。本文着重回顾了红外热成像在急性呼吸道传染性疾病、睡眠呼吸暂停综合征、中医肺疾病研究、新生儿重症监护以及肺栓塞早期筛查等肺部疾病领域中的应用及取得的相关研究进展，具有重要的临床指导意义。红外热成像技术作为一种功能性成像，核心优势在于"早"，不同于疾病过程结构性的改变，疾病早期常出现血流动力学紊乱、局部炎症等所致局部异常温度分布的功能性改变，借助基于热敏性的红外热成像技术可以实现疾病的早期诊断、早期干预以及动态监测等。
