TL;DR: In this article, the authors demonstrate dynamic contrast with a scanning frequency-domain OCT (FD-OCT), which is a promising tool for the histological analysis of unstained tissues.

TL;DR: Endo-microscopic OCT (emOCT) is presented, which may be used for in-vivo imaging of lung diseases like cystic fibrosis or primary ciliary dyskinesia, which manifest already at the nasal mucosa and may considerably improve clinical diagnosis.

TL;DR: A forward-viewing fiber scanning endoscope for high-speed volumetric optical coherence tomography (OCT) by substituting the focusing optics by an all-fiber-based imaging system which consists of a combination of scanning single-mode fibers, a glass spacer, made from a step-index multi-mode fiber, and a gradient-index fiber.

TL;DR: High-speed volumetric mOCT will enable the correction of global tissue motion and is a prerequisite for applying dynamic contrast mO CT in vivo, and may be used to complement or partly replace biopsies.

TL;DR: Short acquisition times and tomographic depth-sectioning reduce the sensitivity of dynamic contrast for bulk tissue motion artifacts and simplify their correction in post-processing, which makes microscopic FD-OCT a promising tool for the histological analysis of unstained tissues.
