Ultra High-Resolution Optical Imaging Catheters

光学相干层析成像(OCT)是一种用于评估软组织表面下结构和功能的体积成像方式。它是超声成像的光学模拟，分辨率提高，但穿透深度降低。高分辨率OCT(10微米)使眼科和心脏科的几种新的临床成像应用成为可能。超高分辨率OCT(1um)已经证明了检测组织中的癌症及其前驱病变所需的细胞分辨率。

Optical coherence tomography (OCT) is a volumetric imaging modality used to assess the subsurface structure and function of soft tissue. It is the optical analog to ultrasonography with improved resolution but albeit decreased penetration depth. High resolution OCT (10 um) has enabled several new clinical imaging applications in ophthalmology and cardiology. Ultra-high resolution OCT (1um) has demonstrated the cellular resolution required to detect cancer and its precursor lesions in tissue.
