What is an Optical Coherence Tomography (OCT)?
OCT is a spectrum-encoded, cross-sectional, and non-invasive imaging device. The future OCT would be able to image thicker samples more efficiently.
What are the current general biomedical imaging applications of OCT?
Field 1: Ophthalmology (eye care)
OCT is commonly used to image the front eye segment and retina non-invasively and label-free, for diagnosis of some eye disorders.
Field 2: Intracoronary (heart blood vessel)
OCT is also used to image the stent attachment in the minimally-invasive surgery obtained to open clogged major coronary arteries.
What is the major obstacle in OCT improvement to image deeper biological tissue for better medical diagnosis?
