摘要

Optical coherence tomography angiography relies on motion for contrast and requires at least two data acquisitions per pointwise scanning location.We present a method termed spectral contrast optical coherence tomography angiography using visible light that relies on the spectral signatures of blood for angiography from a single scan using endogenous contrast.We demonstrate the molecular sensitivity of this method,which enables lymphatic vessel,blood,and tissue discrimination.
