Ultra High-Resolution Optical Imaging Catheters

点击翻译按钮获取中文摘要

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.
