Optical coherence tomography (OCT) delivers 3-dimensional images of tissue microstructures. Although OCT imaging offers a promising high-resolution method, OCT images experience some artifacts that lead to misapprehension of tissue structures. Speckle, intensity decay, and blurring are 3 major artifacts in OCT images. Speckle is due to the low coherent light source used in the configuration of OCT. Intensity decay is a deterioration of light with respect to depth, and blurring is the consequence of deficiencies of optical components. In this short review, we summarize some of the image enhancement algorithms for OCT images which address the abovementioned artifacts.
光学相干断层扫描（OCT）可提供组织微观结构的三维图像。尽管OCT成像提供了一种很有前景的高分辨率方法，但OCT图像存在一些伪影，会导致对组织结构的误解。散斑、强度衰减和模糊是OCT图像中的三大伪影。散斑是由于OCT配置中使用的低相干光源所致。强度衰减是光随深度的劣化，而模糊是光学组件缺陷的结果。在这篇简短的综述中，我们总结了一些用于解决上述伪影的OCT图像增强算法。
