      Swept-source optical coherence tomographic observation on prevalence and variations of cemento-enamel junction morphology
      To investigate the prevalence of different patterns of cemento-enamel junction (CEJ) morphology under swept-source optical coherence tomography (SS-OCT). One hundred extracted human teeth were used consisting of incisors, premolars, and molars. Each sample was observed for every 500 m circumferentially along CEJ and OCT images of the pattern were noted. Microscopic observations were done for the representative sample using confocal laser scanning microscope (CLSM) and transmission electron microscope (TEM). The ...

      Endometrial Vascularization Characterized by Optical Coherence Tomography and Immunohistochemistry in Women Undergoing In Vitro Fertilization-Embryo Transfer Treatment
      Background and objective: Endometrial angiogenesis is a prerequisite for successful pregnancy. Optical coherence tomography (OCT) is a non-invasive physically optical imaging technique widely used in ophthalmology and cardiology. However, there is no study using OCT to evaluate endometrium. The aim of this study was to use OCT and traditionally histological methods to investigate endometrial vascularization in women undergoing in vitro fertilization-embryo transfer (IVF-ET) treatment and to determine the association with ...

      Establishment of healing profile and neointimal transformation in the new polymer-free Biolimus A9-coated coronary stent by longitudinal sequential optical coherence tomography assessments: The EGO-BIOFREEDOM study
      Aims: In patients at high bleeding risk treated with 1 month of dual antiplatelet therapy, the polymer-free, biolimus A9-coated BioFreedom stent (BFS) was found safer and more efficacious than bare metal stents. We used sequential optical coherence tomography (OCT) to assess the time course of strut coverage and neointimal transformation from 1 to 9 months. Methods and results: We randomly assigned 104 BFS recipients to 1 of 5 groups with ...

      Spatio-temporally incremental fiber swept source
      A spatio-temporally incremental fiber sweep source includes a laser light pulse generator for generating light pulses and a fiber array of individual optical fibers. The fiber array has an input end and an output end, with the fibers at the input end receiving the light pulses substantially simultaneously. The optical fibers at the output end are arranged in a raster scan pattern, e.g., a square pattern, wherein the optical ...

      Background Durable polymers used in drug-eluting stents are considered a potential cause of hypersensitivity inflammatory response adversely affecting stent healing. Using a sequential follow-up with optical coherence tomography, we compared the differences in healing profiles of 2 drug-eluting stents with a biodegradable or durable polymer. Methods and Results Sixty patients with multivessel disease were prospectively enrolled to receive both study stents, which were randomly assigned to 2 individual vessels, a ...

      Point-spread function manipulation of the swept-source optical coherence tomography through temporal phase modulation
      Recent breakthroughs in microscopy have surpassed Abbes spatial diffraction limit, especially in the regime of fluorescence imaging. Microcopys depth-imaging relative tomography is, however, still confined to basic imaging quality, which is limited by the Fourier bandwidth. In this paper, we explore the analogy between spatial microscopy and temporal tomography based on the space-time duality, and hence enlighten the advancement of tomography. As a proof-of-principle demonstration, an all-optical manipulation of the ...

      Aims: First-generation DES are associated with delayed endothelial coverage and poor stent healing, increasing the risk of late stent thrombosis, late catch-up and neoatherosclerosis. This observational REMEDEE substudy aimed to examine differences in vascular healing by OCT between the EPC-capture sirolimus-eluting COMBO stent and a paclitaxel-eluting stent (TAXUS). Methods and results: A subset of 33 patients (COMBO=23, TAXUS=10) with de novo coronary artery lesions in the REMEDEE study ...
