Journal ArticleDOI
Dynamic contrast in scanning microscopic OCT.
Michael Münter,Malte vom Endt,Mario Pieper,Malte Casper,Martin Ahrens,Tabea Kohlfaerber,Ramtin Rahmanzadeh,Peter König,Gereon Hüttmann,Hinnerk Schulz-Hildebrandt +9 more
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.
Journal ArticleDOI
Novel endoscope with increased depth of field for imaging human nasal tissue by microscopic optical coherence tomography.
Hinnerk Schulz-Hildebrandt,Mario Pieper,Charlotte Stehmar,Martin Ahrens,Christian Idel,Barbara Wollenberg,Peter König,Gereon Hüttmann +7 more
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.
Journal ArticleDOI
High-speed fiber scanning endoscope for volumetric multi-megahertz optical coherence tomography
Hinnerk Schulz-Hildebrandt,Tom Pfeiffer,Tim Eixmann,Sabrina Lohmann,Martin Ahrens,Joshua Rehra,Wolfgang Draxinger,Peter König,Robert Huber,Gereon Hüttmann +9 more
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.
Journal ArticleDOI
Microscopic optical coherence tomography (mOCT) at 600 kHz for 4D volumetric imaging and dynamic contrast
Michael Münter,Mario Pieper,Tabea Kohlfaerber,Ernst Bodenstorfer,Martin Ahrens,Christian Winter,Robert Huber,Peter König,Gereon Hüttmann,Hinnerk Schulz-Hildebrandt +9 more
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.

Dynamic contrast in scanning microscopic OCT
Michael Münter,Malte vom Endt,Mario Pieper,Malte Casper,Martin Ahrens,Tabea Kohlfaerber,Ramtin Rahmanzadeh,Peter König,Gereon Hüttmann,Hinnerk Schulz-Hildebrandt +9 more
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.
