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

   Explore Article IOPscience (Apr 4 2010) Cardiology

   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 ... (Read Full Article)

   Explore Article Optical Coherence Tomography News (Mar 20 2010) Dentistry

   Feature Of The Week 3/21/10: Periodontitis is currently diagnosed almost entirely on the basis of its clinical manifestations: signs of gingival inflammation (e.g., redness and swelling), probing depth (PD), and level of periodontal attachment or amount of alveolar bone loss. In fact, alveolar bone and periodontal attachment loss represent the results of the destructive aspects of the host defense mechanisms responding to opportunistic infections by bacteria present in the gingival ...

   Explore Article Institute of Physics (Jul 23 2009)

   Abstract. Time-domain optical coherence tomography (OCT) employing a 1300 nm broadband source is used to study flowing blood–saline mixtures with blood concentration ranging from 20% to 100%. The study emphasizes the characteristics of the recorded OCT signal and its connection with the properties of the corresponding fluids. There are three regions with distinct properties along the compounded OCT profiles showing the signal dependence on depth. The recorded OCT signal increases ... (Read Full Article)

    Explore Article Hindawi Publishing Corporation (Jun 12 2008)

    A direct method for the measurement of the optical attenuation coefficient and the scattering anisotropy parameter based on applying the extended Huygens-Fresnel principle to optical coherence tomography images of blood is demonstrated. The images are acquired with a low-power probing beam at the wavelength of 1300 nm. Values of 12.15 mm−1 and 0.95 are found for the total attenuation coefficient and the scattering anisotropy factor, respectively. Also, as a preliminary ... (Read Full Article)
