    2. First interobserver agreement of optical coherence tomography in the bile duct: A multicenter collaborative study

      First interobserver agreement of optical coherence tomography in the bile duct: A multicenter collaborative study
      Background and study aims Optical coherence tomography (OCT) is a new technology available for evaluation of indeterminate biliary strictures. It allows under-the-surface visualization and preliminary studies have confirmed standardized characteristics associated with malignancy. The aim of this study is to evaluate the first interobserver agreement in identifying previously agreed upon OCT criteria and diagnosing of malignant versus benign disease. Patients and methods Fourteen endoscopists were asked to review an atlas ...

    8. Real-time Lissajous imaging with a low-voltage 2-axis MEMS scanner based on electrothermal actuation

      Real-time Lissajous imaging with a low-voltage 2-axis MEMS scanner based on electrothermal actuation
      Laser scanning based on Micro-Electro-Mechanical Systems (MEMS) scanners has become very attractive for biomedical endoscopic imaging, such as confocal microscopy or Optical Coherence Tomography (OCT). These scanners are required to be fast to achieve real-time image reconstruction while working at low actuation voltage to comply with medical standards. In this context, we report a 2-axis Micro-Electro-Mechanical Systems (MEMS) electrothermal micro-scannercapable of imaging large fields of view at high frame rates ...

      Swept-source optical coherence tomography microsystem with an integrated Mirau interferometer and electrothermal micro-scanner
      In the rapid evolution of gastrointestinal endomicroscopy, optical coherence tomography (OCT) has found many diverse applications. Until recently, the micro-optoelectro-mechanical systems (MOEMS) technology has been playing a key role in shaping the miniaturization of these components. We report here, to the best of our knowledge, a novel endoscopic microsystem. It is based on a spectrally tuned MOEMS Mirau micro-interferometer integrated with micro-electro-mechanical systems (MEMS) electro-thermal micro-scanner, operating in the regime ...

    12. Advances in Brain Tumor Surgery for Glioblastoma in Adults

      Advances in Brain Tumor Surgery for Glioblastoma in Adults
      Glioblastoma (GBM) is the most common primary intracranial neoplasia, and is characterized by its extremely poor prognosis. Despite maximum surgery, chemotherapy, and radiation, the histological heterogeneity of GBM makes total eradication impossible, due to residual cancer cells invading the parenchyma, which is not otherwise seen in radiographic images. Even with gross total resection, the heterogeneity and the dormant nature of brain tumor initiating cells allow for therapeutic evasion, contributing to ...

    13. The application of optical coherence tomography angiography in retinal diseases

      The application of optical coherence tomography angiography in retinal diseases
      Optical coherence tomography angiography (OCTA) is a new, noninvasive imaging technique that generates real-time volumetric data on chorioretinal vasculature and its flow pattern. With the advent of high-speed optical coherence tomography, established en face chorioretinal segmentation, and efficient algorithms, OCTA generates images that resemble an angiogram. The principle of OCTA involves determining the change in backscattering between consecutive B-scans and then attributing the differences to the flow of erythrocytes through ...

      Simultaneous refractive index and thickness measurements with a monochromatic low-coherence interferometer
      A scanning monochromatic spatial low-coherent interferometer (S-LCI) can be used to simultaneously measure geometric thickness and refractive index. The probe beam of the scanning S-LCI can be an off-axis converging single wavelength laser beam, and the decomposed incident angles of the beam on the sample can be accurately defined in the Fourier domain. The angle dependent phase shift of a plane parallel plate or other sample can be obtained in ...
