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.
