    2. Quantitative Optical Coherence Tomography Analysis for Late In-Stent Restenotic Lesions

      Quantitative Optical Coherence Tomography Analysis for Late In-Stent Restenotic Lesions

      Coronary optical coherence tomography (OCT) has the potential to identify in-stent neoatherosclerosis, which is a possible risk factor for late acute coronary events after drug-eluting stent implantation. The purpose of this study was to investigate differences between mid-term and late in-stent restenosis after stent implantation by quantitative and semiautomated tissue property analysis using OCT. In total, 1063 OCT image frames of 16 lesions in 15 patients were analyzed. This included 346 frames of 6 lesions in late in-stent restenosis, which was defined as restenosis that was not detected at 6 to 12 months but ≥ 12 months after follow-up coronary angiography ...

    6. Spotty calcification and plaque vulnerability in vivo: frequency domain optical coherence tomography analysis

      Spotty calcification and plaque vulnerability in vivo: frequency domain optical coherence tomography analysis

      Background: Spotty calcification is a morphological characteristic of a vulnerable plaque phenotype. While this calcium pattern is considered an active process, promoted by inflammation, it is unknown whether spotty calcification associates with development of microstructures observed in vulnerable plaques. As frequencydomain optical coherence tomography (FD-OCT) enables visualization of microstructures associated with plaque vulnerability, we investigated the association between spotty calcification and plaque microstructures by using FD-OCT. Methods: A total of 300 patients with stable coronary artery disease (CAD), having clinical indication for percutaneous coronary intervention (PCI), were analyzed. Totally 280 non-culprit lipid plaques within the target vessel requiring PCI were ...

    7. Is it safe to implant bioresorbable scaffolds in ostial side-branch lesions? Impact of ‘neo-carina’ formation on main-branch flow pattern. Longitudinal clinical observations

      Is it safe to implant bioresorbable scaffolds in ostial side-branch lesions? Impact of ‘neo-carina’ formation on main-branch flow pattern. Longitudinal clinical observations

      Formation of a ‘neo-carina’ has been reported after bioresorbable vascular scaffolds (BVS) implantation over side-branches. However, as this ‘neo-carina’ could protrude into the main-branch, its hemodynamic impact remains unknown. We present two cases of BVS implantation for ostial side-branch lesions, and investigate the flow patterns at follow-up and their potential impact. Computational fluid dynamics analysis was performed, using a 3D mesh created by fusion of 3-dimensional angiogram with optical coherence tomography images. In our first case, mild disturbances were seen when ‘neo-carina’ did not protrude perpendicularly into the main branch. In the second case, extensive flow re-distribution was observed due ...

    8. Multi-channel optical coherence tomography for imaging and temperature and force sensing

      Multi-channel optical coherence tomography for imaging and temperature and force sensing

      Embodiments of the invention provide multi-channel OCT (Optical Coherence Tomography) for imaging biological tissue, and for temperature and/or force sensing, preferably in real time. In one embodiment, an optical signal processing system comprises: a processor; a memory; a receiving module to receive in real time input from multiple channels of OCT producing interfering optical signals representing multiple measured distances for a target imaging object; a Fast Fourier Transform (FFT) module to apply FFT on the interfering optical signals in real time to produce Fourier frequencies corresponding to the multiple measured distances; and a calculation module to calculate in real ...

    9. Vascular Data Processing And Image Registration Systems, Methods, And Apparatuses

      Vascular Data Processing And Image Registration Systems, Methods, And Apparatuses

      In part, the invention relates to processing, tracking and registering angiography images and elements in such images relative to images from an intravascular imaging modality such as, for example, optical coherence tomography (OCT). Registration between such imaging modalities is facilitated by tracking of a marker of the intravascular imaging probe performed on the angiography images obtained during a pullback. Further, detecting and tracking vessel centerlines is used to perform a continuous registration between OCT and angiography images in one embodiment.
