Scanning and Actuation Techniques for Cantilever-Based Fiber Optic Endoscopic Scanners—A Review
Sensors, 2021 Endoscopes are used routinely in modern medicine for in-vivo imaging of luminal organs. Technical advances in the micro-electro-mechanical system (MEMS) and optical fields have enabled the further miniaturization of endoscopes, resulting in the ability ...

Endoscopic ultrasound‐guided percutaneous endoscopic gastrostomy
Digestive Endoscopy, 2020 Percutaneous endoscopic gastrostomy (PEG) is the method of choice for feeding and nutritional support in patients with a normal gastrointestinal function who require long‐term enteral nutrition. We report our experience regarding an alternative endoscopic ultrasound (EUS)‐guided PEG technique.

Small-caliber endoscopes are more fragile than conventional endoscopes
Endoscopy International Open, 2019 Background and study aims The repair costs of gastrointestinal endoscopes account for a significant proportion of the total budget of an endoscopy unit. This study evaluated the repair costs of small-caliber endoscopes and conventional endoscopes used in

Smartphone microendoscopy for high resolution fluorescence imaging [PDF]
, 2016 High resolution optical endoscopes are increasingly used in diagnosis of various medical conditions of internal organs, such as the gastrointestinal tracts, but they are too expensive for use in resource-poor settings. On the other hand, smartphones with

Single-shot non-interferometric measurement of the phase transmission matrix in multicore fibers [PDF]
, 2018 A simple technique for far-field single-shot non-interferometric determination of the phase transmission matrix of a multicore fiber with over 100 cores is presented. This phase retrieval technique relies on the aperiodic arrangement of the cores.Comment:

Flexible lensless endoscope with a conformationally invariant multi-core fiber [PDF]
, 2019 The lensless endoscope represents the ultimate limit in miniaturization of imaging tools: an image can be transmitted through a (multi-mode or multi-core) fiber by numerical or physical inversion of the fiber's pre-measured transmission matrix.

Efficacy of a novel channel-cleaning ball brush for endoscope reprocessing: a randomized controlled trial [PDF]
Clinical Endoscopy, 2022 Background/Aims Endoscopic channels are difficult to clean and can cause infection transmission. We examined the effectiveness of a newly developed channel-cleaning ball brush (BB), which is sucked into the endoscopic channel and scrapes and cleans the ...
