Simply put, the working principle of infrared thermal imaging is that it detects the infrared radiation emitted by objects and converts the temperature distribution on object surfaces into video patterns. The higher the temperature of an object, the greater its infrared‑radiation energy. Infrared thermal imaging obtains the temperature distribution across object surfaces by capturing infrared energy. What are its prominent advantages? Let’s take a look with the staff of Kaimorui.

1. High Sensitivity: Infrared thermal imaging features excellent sensitivity. It can pick up thermal radiation generated by human cell metabolism (temperature difference less than 0.025 °C). With specialized imaging and lesion‑highlighting tomographic technology, it visualizes the distribution, depth, intensity, shape and trend of abnormal heat sources inside the human body.
2. Early‑warning Capability: Its most prominent clinical value lies in early warning of physical illnesses. In the early stages of many diseases, only functional (metabolic) changes occur without organic lesions. Temperature changes precede pathological damage, and functional alterations appear earlier than pathological ones.
3. Green and Non‑invasive: Many testing instruments may cause certain harm to the human body. By contrast, infrared thermal imaging produces no rays that would damage human leukocytes.
4. High Accuracy: Infrared thermal imaging delivers high‑precision examinations. Statistics from over one million clinical cases show that its diagnostic accuracy for early malignant tumors reaches 81 %. It can accurately identify and predict early myocardial infarction, cerebral hemorrhage and embolism with an accuracy above 85 %. Its diagnostic accuracy for thyroid, breast, prostate and gynecological diseases exceeds 90 %.
5. Comprehensive Coverage: Infrared thermal imaging covers all bodily systems and organs. A full‑body scan can be completed within 20 minutes.

Besides the merits mentioned above, infrared thermal imaging also offers other strengths: good concealment, immunity to electromagnetic interference, long‑distance thermal‑target tracking, round‑the‑clock all‑weather monitoring, powerful detection capacity and long operating range. It supports multiple display modes, enables detection of energy imperceptible to humans, and directly visualizes surface temperature fields of objects. It is immune to strong light and finds wide‑ranging applications.
