    2. Ex-vivo ultra-high-resolution optical coherence tomography imaging of fine lung structure by use of a high-power Gaussian-like supercontinuum at 0.8-μm wavelength

      Ex-vivo ultra-high-resolution optical coherence tomography imaging of fine lung structure by use of a high-power Gaussian-like supercontinuum at 0.8-μm wavelength
      Optical coherence tomography (OCT) is an emerging technology for non-invasive cross-sectional imaging of biological tissue and material with um resolution. Recently, non-invasive high resolution cross-sectional imaging is desired for investigation of diseases in lung in the field of pulmonary medicine. So far, a few works have been reported about OCT imaging of lung. Since the lung consists of alveoli separated by thin wall, ultrahigh resolution (UHR) OCT is supposed to ...

    3. Dynamic analysis of a small artery of a human finger by optical coherence tomography

      Dynamic analysis of a small artery of a human finger by optical coherence tomography
      OCT is highly potential for development of a new field of dynamic skin physiology, as recently reported by the authors. In this paper, we demonstrate dynamic analysis of a small artery of a human finger by the SS-OCT. Among the vascular system, only the small artery has two physiological functions both for the elastic artery (like main and middle arteries) and for muscle-controlled one (like arterioles). It, therefore, is important ...

    7. Quasi-supercontinuum generation using 1.06μmultrashort-pulse laser system for ultrahigh-resolution optical-coherence tomography

      Quasi-supercontinuum generation using 1.06μmultrashort-pulse laser system for ultrahigh-resolution optical-coherence tomography
      We demonstrate quasi-supercontinuum (quasi-SC) generation around the 1.3 μm wavelength region using ultrahigh-speed, wavelength-tunable, femtosecond soliton pulses based on an ultrashort-pulse laser system operating at a wavelength of 1.0μm. The wavelength tuning range was from 1.0 to 1.9μm, and the scanning speed was up to 1.3MHz. A Gaussian-like quasi-SC with a bandwidth of 220nm was generated at 1220nm. The generated quasi-SC was used in an ...

    8. Spectral-Domain Optical Coherence Tomographic Findings in Myopic Foveoschisis

      Purpose: The purpose of this study was to investigate the sensitivity of various scan modes of spectral-domain optical coherence tomography (SD-OCT) for detecting pathologies that may accompany myopic foveoschisis, which is important for making surgical decisions and planning surgical strategies for myopic foveoschisis. Methods: Twenty-one eyes of 18 patients were diagnosed with myopic foveoschisis by SD-OCT. Patients were examined with SD-OCT using both a five-line raster scan and a three-dimensional ...

    9. Real-time OCT imaging of laser ablation of biological tissue

      Real-time OCT imaging of laser ablation of biological tissue
      During laser ablation of a diseased area, the surrounding tissues and organs suffer serious damage. In order to optimize laser ablation of biological tissues, it is necessary to observe the laser ablation in situ. The real-time imaging of tissue laser ablation is realized in the fusion system of the YAG ablation laser and optical coherence tomography (OCT). A swept-source OCT (SS-OCT) is combined with a YAG-laser ablation system. In this ...

    10. Dynamic analysis of mental sweating by optical coherence tomography

      Dynamic analysis of mental sweating by optical coherence tomography
      In the dynamic OCT of mental sweating, we have found internal mental sweating without ejection of excess sweat from the spiral lumen to the skin surface. Internal sweating occurs more often in the case where mental stress is applied to a volunteer, and it is more useful for evaluation of activity of the sympathetic nerve. Furthermore, the MIP imaging has been proposed for quick 3-D imaging of the spiral lumen ...

    11. The Assessment of the Filtering Bleb Function With Anterior Segment Optical Coherence Tomography

      rpose: To assess the usefulness of anterior segment optical coherence tomography (AS-OCT) in evaluating postoperative filtering bleb function. Methods: Forty-eight eyes of 39 patients who had earlier undergone trabeculectomy were enrolled. Blebs were imaged with a commercially available AS-OCT system. The correlation between intraocular pressure (IOP) and 4 quantitative parameters, bleb height, bleb wall thickness, and the height and extent of internal cavity, and 2 qualitative parameters, bleb wall reflectivity ...

    12. Progress of OCT and its applications

      Optical coherence tomography (OCT) is the cross-sectional imaging of biological tissue based on the low-coherence interferometry, where the image resolution is around 10 m with the imaging depth of 1 to 2 mm. Since its first demonstration, OCT has been developed intensively for clinical diagnoses of ophthalmology and arteriosclerosis. Beside the clinical applications, OCT is used for analysis of physiological functions underneath the human skin surface. Recently, we proposed and ...
