The Enabling Technologies of OCT Angiography

Optical Coherence Tomography (OCT) angiography opens another exciting chapter in ophthalmic imaging.  Based on motion contrast, and in the presence of motion-less structure, OCT angiography (OCT-A) resolves signal due to moving blood flow.  It thereby offers a compelling alternative to…
