    4. Optical Coherence Tomography System And Optical Coherence Tomography Method (Wo 2009/124569)

      Optical Coherence Tomography System And Optical Coherence Tomography Method (Wo 2009/124569)
      The invention relates to an optical coherence tomography system comprising an interferometer, in particular a Michelson-interferometer, provided with a reference arm (R) for modifying an optical reference wave length and a measuring arm (M), in which an object (sample P) that is to be scanned can be arranged and/or is arranged in a sample volume (PV). Said optical coherence tomography device is characterised in that a focusing system (F ...

    6. Comparison of two in vivo microscopy techniques to visualize alveolar mechanics

      Objective In conventional in vivo microscopy, a three dimensional illustration of tissue is lacking. Concerning the microscopic analysis of the pulmonary alveolar network, surgical preparation of the thorax and fixation of the lung is required to place the microscope’s objective. These effects may have influence on the mechanical behaviour of alveoli. Relatively new methods exist for in vivo microscopy being less invasive and enabling an observation without fixation of ...

    7. Alveolar dynamics in acute lung injury: Heterogeneous distension rather than cyclic opening and collapse *

      Objectives: To analyze alveolar dynamics in healthy and acid-injured lungs of ventilated mice. Protective ventilation is potentially lifesaving in patients with acute lung injury. However, optimization of ventilation strategies is hampered by an incomplete understanding of the effects of mechanical ventilation at the alveolar level. Design: In anesthetized and ventilated Balb/c mice, subpleural alveoli were visualized by darkfield intravital microscopy and optical coherence tomography. Setting: Animal research laboratory. Subjects ...

    8. Blood flow measurement in the in vivo mouse model by the combination of Doppler OCT and the signal power decrease in spectral domain OCT

      Blood flow measurement with spectrometer-based Fourier domain optical coherence tomography (FD OCT) is limited by the motion-induced signal fading and the resulting reduction of flow sensitivity. In this study, a combination of the established Doppler OCT and the numerically simulated signal damping due to obliquely moved scatterers is used to estimate the systolic blood flow velocities in the in vivo mouse model at which the standard Doppler OCT does not ...

    9. In-vivo Fourier domain optical coherence tomography as a new tool for investigation of vasodynamics in the mouse model

      In-vivo imaging of the vascular system can provide novel insight into the dynamics of vasoconstriction and vasodilation. Fourier domain optical coherence tomography (FD-OCT) is an optical, noncontact imaging technique based on interferometry of short-coherent near-infrared light with axial resolution of less than 10 µm. In this study, we apply FD-OCT as an in-vivo imaging technique to investigate blood vessels in their anatomical context using temporally resolved image stacks. Our chosen ...
