Body temperature is a very useful parameter for diagnosing diseases. There is a definite correlation between body temperature and diseases. We have used Infrared Thermography to study noninvasive diagnosis of peripheral vascular diseases. Temperature gradients are observed in the affected regions of patients with vascular disorders, which indicate abnormal blood flow in the affected region. Thermal imaging results are well correlated with the clinical findings. Certain areas on the affected limbs show increased temperature profiles, probably due to inflammation and underlying venous flow changes. In general the temperature contrast in the affected regions is about 0.7 to 1 degrees C above the normal regions, due to sluggish blood circulation. The results suggest that the thermal imaging technique is an effective technique for detecting small temperature changes in the human body due to vascular disorders.
体温是诊断疾病的一个非常有用的参数。体温与疾病之间存在明确的关联。我们已经使用红外热成像技术来研究外周血管疾病的无创诊断。在血管疾病患者的受影响区域观察到温度梯度，这表明受影响区域存在异常血流。热成像结果与临床发现密切相关。受影响肢体上的某些区域显示温度分布增加，这可能是由于炎症和潜在的静脉血流变化所致。一般来说，由于血液循环不畅，受影响区域的温度对比比正常区域高约0.7至1摄氏度。结果表明，热成像技术是一种检测人体因血管疾病引起的微小温度变化的有效技术。
