摘要
光学相干断层扫描（OCT）可提供组织微观结构的三维图像。虽然 OCT 成像是一种很有前景的高分辨率方法，但 OCT 图像会出现一些伪影，导致对组织结构的误解。斑点、强度衰减和模糊是 OCT 图像中的三大伪像。斑点是由于 OCT 配置中使用的低相干光源造成的。强度衰减是光线随深度的衰减，而模糊则是光学元件缺陷的结果。在这篇简短的综述中，我们总结了一些针对上述伪影的 OCT 图像增强算法。
Optical Coherence Tomography Technology and Quality Improvement Methods for Optical Coherence Tomography Images of Skin: A Short Review.
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.
