    3. IMPROVED ARTERIAL TISSUE DIFFERENTIATION BY SPECTROSCOPIC OPTICAL COHERENCE TOMOGRAPHY

      IMPROVED ARTERIAL TISSUE DIFFERENTIATION BY SPECTROSCOPIC OPTICAL COHERENCE TOMOGRAPHY
      Optical coherence tomography (OCT) is a relatively new imaging modality similar with ultrasound where the sound waves are replaced by ballistic photons. OCT provides images at high spatial resolution which allow for the identification of micron size morphological tissue structures. A high impact application is visualization of arterial wall and atherosclerotic plaques. Despite high spatial resolution to complete the transfer of this imaging modality into clinical environment there is a ...

    4. Optical catheter with rotary optical cap

      Optical catheter with rotary optical cap
      A scanning optical head for a catheter is locally controlled by a motor at an insertion end of the catheter uses a hollow motor through which a longitudinal optical path of the catheter passes. This permits the motor to be positioned between a control base of the catheter and avoids rotating the whole fiber, and therefore makes the beam scanning stable and accurate. In addition, because there is no coupling ...

    5. Numerical simulation of a gradient-index fibre probe and its properties of light propagation

      Numerical simulation of a gradient-index fibre probe and its properties of light propagation
      In order to verify the properties of the light propagating through a gradient-index (GRIN) fibre probe for optical coherence tomography (OCT), numerical simulation using the optical software GLAD is carried out. Firstly, the model of the GRIN fibre probe is presented, which is consisted of a single mode fibre (SMF), a no-core fibre (NCF), a GRIN fibre lens and an air path. Then, the software GLAD is adopted to numerically ...

    6. Dual-Source Swept-Source Optical Coherence Tomography Reconstructed on Integrated Spectrum

      Dual-Source Swept-Source Optical Coherence Tomography Reconstructed on Integrated Spectrum
      Dual-source swept-source optical coherence tomography (DS-SSOCT) has two individual sources with different central wavelengths, linewidth, and bandwidths. Because of the difference between the two sources, the individually reconstructed tomograms from each source have different aspect ratio, which makes the comparison and integration difficult. We report a method to merge two sets of DS-SSOCT raw data in a common spectrum, on which both data have the same spectrum density and a ...

    8. Performance analysis of a swept-source optical coherence tomography system with a quadrature interferometer and optical amplification

      Performance analysis of a swept-source optical coherence tomography system with a quadrature interferometer and optical amplification
      A performance analysis of signal to noise ratio for an optical coherence tomography system with quadrature detection and a semiconductor optical amplifier in the sample arm is discussed. The results are compared and discussed in relation to a conventional OCT system (without optical amplification). An increase of the signal to noise ratio up to 14 dB at a depth of 0.5 mm is obtained compared to the system without ...
