目的:微循环异常可能参与了高血压、高血脂、糖尿病等血管疾病发生发展并在其中起重要作用。目前血流测定的方法有荧光示踪、同位素、红外摄像、局部温度、激光多普勒、超声多普勒等,其中激光多普勒血流成像法克服了超声多普勒法对人体浅表部位测量盲区和测量时需要接触并加藕合剂的缺点,并以无创伤、操 OBJECTIVE: Anomalies of microcirculation may participate in the development of vascular diseases such as hypertension, hyperlipidemia and diabetes and play an important role in them. Current blood flow measurement methods are fluorescent tracer, isotope, infrared camera, local temperature, laser Doppler, Doppler ultrasound, etc., of which laser Doppler flow imaging method to overcome the ultrasound Doppler on the human body superficial Parts of the blind spot measurement and measurement need to contact and add the shortcomings of coupling agent, and non-invasive,
