A system for full-field laser Doppler blood flow imaging has been developed and tested on biomedical samples. The new imaging system allows 2D flow maps or monitoring flux signals to be obtained from a plurality of measured points simultaneously by using a 2D array of photodetectors. The detection part of the system is based on an intelligent CMOS camera with a built-in digital signal processor and memory. The imaging time of the system is as much as to 4 times faster than for the conventional scanning laser Doppler imager. The performance of the system was evaluated in vitro and in vivo. The first measurement results with this new system on human skin are reported.
一种用于全场激光多普勒血流成像的系统已被开发出来，并在生物医学样本上进行了测试。这种新的成像系统通过使用二维光电探测器阵列，能够同时从多个测量点获取二维血流图或监测通量信号。该系统的检测部分基于一个内置数字信号处理器和存储器的智能CMOS相机。该系统的成像时间比传统扫描激光多普勒成像仪快多达4倍。该系统的性能在体外和体内进行了评估。报告了使用这种新系统对人体皮肤的首次测量结果。
