    2. Optical coherence tomography revisited: imaging and imagination

      Optical coherence tomography revisited: imaging and imagination
      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 ...

    3. Multiple sclerosis: is it all black and white in optical coherence tomography?

      Multiple sclerosis: is it all black and white in optical coherence tomography?
      This scientific commentary refers to Brain and retinal atrophy in African-Americans versus Caucasian-Americans with multiple sclerosis: a longitudinal study, by Gonzalez Caldito et al. (doi: 10.1093/brain/awy245 ). ... Multiple sclerosis is an inflammatory demyelinating disease of the CNS. Histopathologically, degenerative processes have also been identified early in the disease course and independent of the demyelinating white matter disease. MRI of brain atrophy is currently the gold standard to assess ...

    4. Ultra low noise Fourier domain mode locked laser for high quality megahertz optical coherence tomography

      Ultra low noise Fourier domain mode locked laser for high quality megahertz optical coherence tomography
      We investigate the origin of high frequency noise in Fourier domain mode locked (FDML) lasers and present an extremely well dispersion compensated setup which virtually eliminates intensity noise and dramatically improves coherence properties. We show optical coherence tomography (OCT) imaging at 3.2 MHz A-scan rate and demonstrate the positive impact of the described improvements on the image quality. Especially in highly scattering samples, at specular reflections and for strong ...

    5. Towards Robotic Eye Surgery: Marker-free, Online Hand-eye Calibration using Optical Coherence Tomography Images

      Towards Robotic Eye Surgery: Marker-free, Online Hand-eye Calibration using Optical Coherence Tomography Images
      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 ...

    6. Neoatherosclerosis in Patients With Coronary Stent Thrombosis: Findings From Optical Coherence Tomography Imaging (A Report of the PRESTIGE Consortium)

      Neoatherosclerosis in Patients With Coronary Stent Thrombosis: Findings From Optical Coherence Tomography Imaging (A Report of the PRESTIGE Consortium)
      Objectives The purpose of this study was to assess neoatherosclerosis in a registry of prospectively enrolled patients presenting with stent thrombosis using optical coherence tomography . Background In-stent neoatherosclerosis was recently identified as a novel disease manifestation of atherosclerosis after coronary stent implantation. Methods Angiography and intravascular optical coherence tomography were used to investigate etiologic factors of neoatherosclerosis in patients presenting with stent thrombosis 1 year after implantation (very late stent ...

      Very late scaffold thrombosis: insights from optical coherence tomography and histopathology
      A 79-year-old male patient had a 2.512 mm bioresorbable vascular scaffold (Absorb BVS; Abbott Vascular, Santa Clara, CA, USA) implanted in the setting of the RIBS VI study protocol for in-stent restenosis of a 39 mm bare metal stent (AVE S670; Medtronic, Minneapolis, MN, USA) in January 2015, at which time point the patient presented with stable angina and positive exercise stress test (index procedure). The Absorb BVS was ...

      Very Late Scaffold Thrombosis: Insights from Optical Coherence Tomography and Histopathology
      Aims: to investigate and understand the mechanisms of very late scaffold thrombosis 13 months following implantation in the setting of bare metal in-stent restenosis. Methods and results: we collected consecutive angiography, optical coherence tomography and full autopsy evaluation in a 79-year old patients presenting with cardiogenic shock and undergoing rescue PCI after suffering very late scaffold thrombosis. Combined assessment of angiography, optical coherence tomography and histopathology revealed heterogenous vascular healing ...

    10. Needle Segmentation in Volumetric Optical Coherence Tomography Images for Ophthalmic Microsurgery

      Needle Segmentation in Volumetric Optical Coherence Tomography Images for Ophthalmic Microsurgery
      Needle segmentation is a fundamental step for needle reconstruction and image-guided surgery. Although there has been success stories in needle segmentation for non-microsurgeries, the methods cannot be directly extended to ophthalmic surgery due to the challenges bounded to required spatial resolution. As the ophthalmic surgery is performed by finer and smaller surgical instruments in micro-structural anatomies, specifically in retinal domains, difficulties are raised for delicate operation and sensitive perception. To ...

    11. Optical Coherence Tomography Findings in Patients with Coronary Stent Thrombosis: A Report of the PREvention of Late Stent Thrombosis by an Interdisciplinary Global European Effort (PRESTIGE) Consortium

      Optical Coherence Tomography Findings in Patients with Coronary Stent Thrombosis: A Report of the PREvention of Late Stent Thrombosis by an Interdisciplinary Global European Effort (PRESTIGE) Consortium
      Background Stent thrombosis (ST) is a serious complication following coronary stenting. Intravascular optical coherence tomography (OCT) may provide insights into mechanistic processes leading to ST. We performed a prospective, multicenter study to evaluate OCT findings in patients with ST. Methods Consecutive patients presenting with ST were prospectively enrolled in a registry using a centralized telephone registration system. After angiographic confirmation of ST, OCT imaging of the culprit vessel was performed ...

      Optical coherence tomography in drug-eluting stent restenosis: a technique in need of a strategy
      Despite the high anti-restenotic efficacy of contemporary percutaneous interventional techniques, a substantial number of patients who undergo percutaneous coronary intervention (PCI) still present with restenosis. Despite iterations of devices from plain balloon angioplasty to bare metal stenting (BMS) to drug-eluting stent (DES) therapy have granted a progressive decline in the rate of this complication, in-stent restenosis remains a critical issue encountered in clinical practice. Owing to the overall increase in ...

      Markedly different tissue types on optical coherence tomography imaging in a patient with multiple lesion drug-eluting stent in-stent restenosis
      The treatment of in-stent restenosis after drug-eluting stent (DES) implantation remains a major clinical challenge. Optical coherence tomography (OCT) imaging at the time of presentation can provide important information on mechanical factors contributing to stent failure as well as on tissue characteristics of the in-stent neointimal tissue. We report a case of markedly different tissue typescharacterized by heterogeneous and homogeneous signal intensityobserved in a patient with multiple lesion DES in-stent ...
