Novel image-enhanced endoscopy with i-scan technology

World Journal of Gastroenterology, 2010
i-scan technology is the newly developed image-enhanced endoscopy technology from PENTAX, Japan. This consists of three types of algorithms: surface enhancement (SE), contrast enhancement (CE), and tone enhancement (TE). SE enhances light-dark contrast by obtaining luminance intensity data for each pixel and applying an algorithm that allows detailed ...

Beyond Standard Image-enhanced Endoscopy Confocal Endomicroscopy

Gastrointestinal Endoscopy Clinics of North America, 2014
Endomicroscopy is a new imaging tool for gastrointestinal endoscopy. In vivo histology becomes possible at subcellular resolution during ongoing colonoscopy. Panchromoendoscopy with targeted biopsies has become the method of choice for surveillance of patients with inflammatory bowel disease. Endomicroscopy can be added after chromoendoscopy to clarify

Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms

Advanced Materials Technologies, EarlyView.
3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...
