摘要
基于光学多普勒效应的无创血流测量技术具有实时性、无需介质、非侵入式等性质,在临床医疗等领域存在着极大价值与应用前景。目前光学无创血流测量技术主要有激光多普勒血流测量技术、光学相干层析多普勒成像技术和光声多普勒血流测量技术。对这3种技术进行了原理分析,简述了其研究现状,并对这些新型技术的未来和发展进行了展望。
Due to the properties of real-time,medium-free,and non-invasive,the optical Doppler effect based non-invasive blood flow measurement is valuable and has a promising future in clinical and other fields.At present,there are three optical non-invasive blood flow measurement technologies:laser Doppler blood flow measurement technology,optical coherence tomography Doppler imaging technology,and photo-acoustic Doppler blood flow measurement technology.The principles of the above three technologies were briefly analyzed,the respective development status was described,and the future and development of these new technologies were exhibited.
