摘要

摘 要:光学相干层析血管造影(OCTA)以光学相干层析(OCT)为基础,是一种新型、无损、快速、安全的三维血管成像技术。OCTA成像的方法有多种,根据其算法使用的OCT信号信息可将其分为基于相位、振幅和复合信号3种类型。本文在描述各类型的成像原理、算法及其优缺点后,对3种类型的OCTA方法进行了比较,其中使用复合信号的类型成像质量最好。同时,结合OCTA的研究进展对其未来的发展进行了展望。

Abstract

Abstract: Based on OCT, OCTA is a newly invented, non-invasive, fast and safe technology of volumetric imaging about blood flow. According to the OCT signal information they use, methods of OCTA can be divided into three categories: phase based algorithms, amplitude based algorithms and complex algorithms. After depicting the imaging principle, specific algorithm and advantages/disadvantages, methods of these three categories are compared in which complex category achieve best performance on imaging. Research progress is combined to discuss the prospect of OCTA.
