Abstract

Choroid is a tissue with a very high blood flow which is a metabolic supporter of the retina. Recently, the study of choroidal blood flow in ocular and systemic disorders is a hot topic in scientific research. With the advent of enhanced depth imaging OCT (EDI-OCT), it is possible to measure the entire choroidal thickness. The choroidal vascularity index (CVI) is a relatively new index in studying choroidal hemodynamics. However, the CVI measurement needs image processing. Image calibration is a necessary step before any image processing with software such as ImageJ.

脉络膜血管指数测量中的图像校准。

脉络膜是一种血流量非常高的组织，是视网膜的代谢支持物。近年来，脉络膜血流在眼部和全身疾病中的研究是科学研究的热点。随着增强型深度成像OCT（EDI-OCT）的出现，可以测量整个脉络膜厚度。脉络膜血管指数（CVI）是研究脉络膜血流动力学的一个相对较新的指标。然而，CVI测量需要图像处理。在使用诸如ImageJ之类的软件进行任何图像处理之前，图像校准是必要的步骤。
