Infrared thermal imaging technology is of certain reference significance in the assistant diagnosis and response evaluation of myocardial ischemia in coronary heart disease (CHD). At present, the study of infrared thermal imaging technology in CHD is still in the preliminary stage. It mainly includes the exploration of correlation between CHD and the relative body surface related areas and acupoints, as well as comparison between the assistant diagnosis and curative effect assessment of CHD. But there still exists lots of shortcomings. In this paper, the research status of infrared thermal ima...
