非侵入性血管造影术证明了在体内人眼。三维流动成像已与高速光谱域光学相干断层扫描。通过两种算法对样本运动进行补偿。一幅OCT图像内相邻A线之间的轴向运动通过由于大量样本运动而产生的多普勒频移进行补偿。相邻图像之间的轴向位移通过基于相关性的算法进行补偿。眼部血管的三维脉管系统已经可视化。通过对血流图像的体积集进行积分，获得血管的二维图像。通过将体积集分离成视网膜部分和脉络膜部分，同时获得视网膜和脉络膜血管图像。这些对应于荧光素血管造影和吲哚菁血管造影。(c)2006年美国光学学会。
Noninvasive angiography is demonstrated for the in vivo human eye. Three-dimensional flow imaging has been performed with high-speed spectral-domain optical coherence tomography. Sample motion is compensated by two algorithms. Axial motion between adjacent A-lines within one OCT image is compensated by the Doppler shift due to bulk sample motion. Axial displacements between neighboring images are compensated by a correlation-based algorithm. Three-dimensional vasculature of ocular vessels has been visualized. By integrating volume sets of flow images, two-dimensional images of blood vessels are obtained. Retinal and choroidal blood vessel images are simultaneously obtained by separating the volume set into retinal part and choroidal parts. These are corresponding to fluorescein angiogram and indocyanine angiogram. (c) 2006 Optical Society of America.
