    1. 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 ...

    2. 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 ...

    3. Added soft tissue contrast using signal attenuation and the fractal dimension for optical coherence tomography images of porcine arterial tissue

      Added soft tissue contrast using signal attenuation and the fractal dimension for optical coherence tomography images of porcine arterial tissue
      Optical coherence tomography (OCT) images of left-descending coronary tissues harvested from three porcine specimens were acquired with a home-build swept-source OCT setup. Despite the fact that OCT is capable of acquiring high resolution circumferential images of vessels, many distinct histological features of a vessel have comparable optical properties leading to poor contrast in OCT images. Two classification methods were tested in this report for the purpose of enhancing contrast between ...
