Narrow band imaging cholangioscopy in hilar cholangiocarcinoma
Indian Journal of Gastroenterology, 2010Per oral cholangioscopy has been developed as a diagnostic modality for evaluation of bile duct lesions. Per oral cholangioscope with narrow band imaging (NBI) system can provide good quality images of bile duct lesions. There is limited data on per oral cholangioscopy using NBI in biliary tract diseases.

Cystoscopy and transurethral resection (TUR) using white light (WL) has been used as a standard procedure for diagnosis and treatment of non-muscle invasive bladder cancer (NMIBC). However, WL cystoscopy cannot always effectively identify small tumor or high grade flat lesions, carcinoma in situ (CIS). Small tumors can be frequently missed resulting in

Narrow Band High Resolution Radar Imaging
2006 IEEE Conference on Radar, 2006We present a technique for generating imagery with high spatial resolution but from low bandwidth radar transmissions. The high spatial resolution is obtained by applying the principles of tomography to a multi-site monochromatic continuous wave (CW) radar system that can illuminate the target over a complete angular range of 360 degrees.

Narrow-Band Imaging Evaluation of Bladder Tumors
Current Urology Reports, 2014Narrow-band imaging (NBI) is a novel optical method designed to enhance visual detection of bladder tumors over conventional white-light imaging (WLI) cystoscopy. Current experience with NBI cystoscopy in evaluating and treating non-muscle-invasive bladder tumors is reviewed.

[Endourological imaging with narrow band imaging].
Der Urologe. Ausg. A, 2012Narrow band imaging (NBI) is an optical diagnostic procedure which utilizes the narrowing of the wavelength of visible light in the range between 415 and 550 nm. The NBI is mostly used for the diagnostics of inflammation or tumors of the gastrointestinal tract.

Novel endoscopic technologies: narrow band imaging
European Surgery, 2008BACKGROUND: Narrow Band Imaging (NBI) is a novel imaging technique based on the exclusion of deeper penetrating light from the colour spectrum. METHODS: Review on the current status of narrow band imaging. RESULTS: Pictures taken using NBI are characterised by contrast-enhancement of mucosal structures and visualisation of mucosal vascular pattern. NBI

Advances in endoscopic imaging: narrow band imaging.
Reviews in gastroenterological disorders, 2008Technological advances in endoscopic imaging are constantly being evaluated in clinical research, and encouraging results are being seen. Studies on practical applications of these new technologies are ongoing in conditions as diverse as gastroesophageal reflux disease, Barrett's esophagus, colonic polyps, and dysplasia in ulcerative colitis.

Endourologische Bildgebung mittels „narrow band imaging“
Der Urologe, 2012„Narrow band imaging“ (NBI) ist ein optisches Diagnoseverfahren und beruht auf einer Einengung der Wellenlange des sichtbaren Lichts in einen Bereich zwischen 415 und 550 nm. Meistens wird NBI zur Diagnostik von Entzundungen oder Tumorerkrankungen des Magen-Darm-Trakts eingesetzt. Erste Untersuchungen zur Diagnostik von Harnblasenkarzinomen mittels NBI
