Correction of rotational distortion for catheter-based en face OCT and OCT angiography.
We demonstrate a computationally efficient method for correcting the nonuniform rotational distortion (NURD) in catheter-based imaging systems to improve endoscopic en face optical coherence tomography (OCT) and OCT angiography. The method performs nonrigid registration using fiducial markers on the catheter to correct rotational speed variations. Algorithm performance is investigated with an u...
متن کاملUltrahigh speed endoscopic optical coherence tomography using micromotor imaging catheter and VCSEL technology
We developed a micromotor based miniature catheter with an outer diameter of 3.2 mm for ultrahigh speed endoscopic swept source optical coherence tomography (OCT) using a vertical cavity surface-emitting laser (VCSEL) at a 1 MHz axial scan rate. The micromotor can rotate a micro-prism at several hundred frames per second with less than 5 V drive voltage to provide fast and stable scanning, whic...
متن کاملOver-the-scope clip-assisted endoscopic full-thickness resection after incomplete resection of rectal adenocarcinoma.
Endoscopic resection is a valuable therapeutic option for early colorectal cancer (CRC), especially in high risk surgical patients [1]. A novel endoscopic full-thickness resection device (FTRD; Ovesco Endoscopy, Tübingen, Germany) has been developed recently to achieve complete endoscopic resection of early CRC [2,3]. Here, we report the case of a 78-year-old manwith a history of coronary arter...
متن کاملPiezoelectric-transducer-based miniature catheter for ultrahigh-speed endoscopic optical coherence tomography
We developed a piezoelectric-transducer- (PZT) based miniature catheter with an outer diameter of 3.5 mm for ultrahigh-speed endoscopic optical coherence tomography (OCT). A miniaturized PZT bender actuates a fiber and the beam is scanned through a GRIN lens and micro-prism to provide high-speed, side-viewing capability. The probe optics can be pulled back over a long distance to acquire three-...
متن کاملThe evil lies below the surface: Subsquamous tumor extension in Barrett’s adenocarcinoma
The presence of intestinal metaplasia underneath the surrounding squamous epithelium is a well known phenomenon in Barrett’s esophagus (BE) [1]. Mostly caused by re-epithelialization with neosquamous epithelium in the context of mucosal healing (due to acid suppressive therapy or after biopsy sampling, for example), this issue has recently attracted new attention in the context of an increasing...
