摘　　要：1975年Stern首次将激光多普勒血流仪（LDF）应用于血流探测，但探头需接触探测部位，易引起创面感染，且接触面积仅为1mm×1mm，限制了其应用。20世纪八九十年代这项技术得到改进，发展为无需接触探测部位，通过全面扫描创面，即可描绘出整个创面二维血流值的成像技术，即激光多普勒血流灌注成像（LDPI）。Laser Doppler perfusion imaging （LDPI） works through the Doppler effect of lighl wave, and it could de- pict tile blood flow value of the entire wound in twu-dimensional image wilhout contaeling tile detection site directly. In resent years, LDPI has been proved to be effective to evaluate healing potential of a wound, and to predict burn depth and sear forma- tion. The accuracy of LDPI is higher than other traditional meth- ods and technique. However, there are still many influencing factors for tile clinical application of LDPI sca,lning. This paper presents a comprehensive overview of advances in the research of LDPI for clinical application in the care of burn wounds and in- fluencing factors for accurate scanning.
