2. Validation and application of OCT tissue attenuation index for the detection of neointimal foam cells
  
  Explore Home - Springer Aug 8 2020 Cardiology
  
  Neointimal infiltration with foamy macrophages is recognized as an early and important sign of de-novo atherosclerosis after stent implantation (neoatherosclerosis). Recent histopathological studies have proven that automated quantification of signal attenuation using intravascular optical coherence tomography (OCT) imaging allows for sensitive identification of macrophages in native atherosclerotic disease. Whether this is true for neointimal foam cells in the setting of neoatherosclerosis remains unknown. Autopsy samples of stented coronary arteries (n ...

4. Automatic intraoperative optical coherence tomography positioning
  
  Explore Home - Springer Apr 9 2020 Ophthalmology
  
  Purpose Intraoperative optical coherence tomography (iOCT) was recently introduced as a new modality for ophthalmic surgeries. It provides real-time cross-sectional information at a very high resolution. However, properly positioning the scan location during surgery is cumbersome and time-consuming, as a surgeon needs both his hands for surgery. The goal of the present study is to present a method to automatically position an iOCT scan on an anatomy of interest in ...

5. Subintimal Versus Intraplaque Recanalization of Coronary Chronic Total Occlusions: Mid-Term Angiographic and OCT Findings From the ISAR-OCT-CTO Registry
  
  Explore ScienceDirect Sep 17 2019 Cardiology
  
  Objectives The aim of this study was to compare angiographic and optical coherence tomography findings following subintimal as opposed to intraplaque recanalization of chronic total occlusions (CTOs). Background There is ongoing controversy regarding outcomes of intraplaque versus subintimal CTO recanalization. Methods Consecutive patients undergoing angiography and intravascular optical coherence tomography following CTO recanalization were included in the ISAR-OCT-CTO (Intracoronary Stenting and Angiographic Results - Optical Coherence Tomography for Chronic Total Occlusions ...

8. Optical coherence tomography tissue coverage and characterization with grey-scale signal intensity analysis after bifurcation stenting with new generation bioabsorbable polymer drug-eluting stent
  
  Explore ScienceDirect May 11 2019 Cardiology
  
  Purpose Bifurcation stenting is thought to be associated with delayed healing and a subsequent risk of stent failure. The aim of this study was to further evaluate healing of thin-strut bioabsorbable polymer everolimus-eluting stents (EES) post bifurcation stenting by optical coherence tomography (OCT) including grey-scale signal intensity (GSI) analysis. Methods Patients receiving bifurcation stenting with a planned two-stent approach using EES with OCT follow-up at 36 months post-stenting were included ...

9. Process control and quality assurance in remote laser beam welding by optical coherence tomography
  
  Explore Journal of Laser Applications Apr 20 2019 NDE/NDT
  
  Remote laser beam welding significantly outperforms conventional joining techniques in terms of flexibility and productivity. This process benefits in particular from a highly focused laser radiation and thus from a well-defined heat input. The small spot sizes of high brilliance laser beam sources, however, require a highly dynamic and precise positioning of the beam. Also, the laser intensities typically applied in this context result in high process dynamics and in ...

  As a result of the rapidly growing importance of applications in electro mobility that require a precisely defined laser weld depth, the demand for inline process monitoring and control is increasing. To overcome the challenges in process data acquisition, this paper proposes the application of a novel sensor concept for deep penetration laser beam welding with high brilliance laser sources. The experiments show that optical coherence tomography (OCT) can be ...

12. Optical coherence tomography revisited: imaging and imagination
  
  Explore eurointervention.org Nov 21 2018 Cardiology
  
  Optical coherence tomography (OCT) was introduced into cardiovascular imaging in 1997 1 , emerging as a spin-off from an original scientific invention within the field of ophthalmology to enable imaging of retinal microstructures including arterioles and to facilitate detection of early degenerative changes of retinopathies. Consequently, OCT was praised as being a ground-breaking imaging technology which provides a far superior resolution as compared to the already established ultrasound-based imaging system (intravascular ...

  Ophthalmic microsurgery is known to be a challenging operation, which requires very precise and dexterous manipulation. Image guided robot-assisted surgery (RAS) is a promising solution that brings significant improvements in outcomes and reduces the physical limitations of human surgeons. However, this technology must be further developed before it can be routinely used in clinics. One of the problems is the lack of proper calibration between the robotic manipulator and appropriate ...
