2. Method and apparatus for measurement of optical properties in tissue

   Explore Article uspto.gov (Aug 31 2010) Patents , Probes

   A method of analyzing tissue includes inserting a radiation source into tissue, impinging radiation upon the tissue, obtaining a sample signal of the radiation that impinges upon the tissue, and determining a refractive index of the tissue from the sample signal. The method may also include determining at least one other optical property of the tissue. The method may provide for identifying tissue as part of a biopsy method. A ... (Read Full Article)

4. Speckle reduction in optical coherence tomography by strain compounding

   Explore Article opticsinfobase.org (Jul 13 2010)

   We present a speckle reduction technique for optical coherence tomography based on strain compounding. Decorrelation is introduced between B-scans by altering the sample’s strain. A theoretical description of the technique, based on a transfer-function formalism, and experimental results on silicone phantoms are presented. Nearly complete decorrelation between successive B-scan speckle patterns was observed for a variation in strain of 0.045. Strain compounding by averaging nine B-scans, with 0.003 strain increments ... (Read Full Article)

5. Detection of multiple scattering in optical coherence tomography by speckle correlation of angle-dependent B-scans

   Explore Article opticsinfobase.org (Jun 8 2010)

   Angular diversity is a successful speckle-reduction technique in optical coherence tomography (OCT). We employ angle-dependent detection for a different purpose: to distinguish the singly backscattered and multiply scattered signal components. Single backscattering is highly correlated over a large range of detection angles; multiple scattering rapidly decorrelates as the angle is varied. Theoretical justification is provided using a linear-systems description of the OCT imaging process; detection of multiple scattering is corroborated ... (Read Full Article)

9. Distribution of airway narrowing responses across generations and at branching points, assessed in vitro by anatomical optical coherence tomography

   Explore Article Respiratory Research (Jan 23 2010) Pulmonology

   Background Previous histological and imaging studies have shown the presence of variability in the degree of bronchoconstriction of airways sampled at different locations in the lung (i.e., heterogeneity). Heterogeneity can occur at different airway generations and at branching points in the bronchial tree. Whilst heterogeneity has been detected by previous experimental approaches its spatial relationship either within or between airways is unknown. Methods In this study, distribution of airway narrowing ... (Read Full Article)

    Explore Article opticsinfobase.org (Nov 12 2009)

    We present a novel sample arm arrangement for dynamic optical coherence elastography based on excitation by a ring actuator. The actuator enables coincident excitation and imaging to be performed on a sample, facilitating in vivo operation. Sub-micrometer vibrations in the audio frequency range were coupled to samples that were imaged using optical coherence tomography. The resulting vibration amplitude and microstrain maps are presented for bilayer silicone phantoms and multiple skin ... (Read Full Article)

12. In vivo 4D imaging of the human lower airway using anatomical optical coherence tomography

    Explore Article SPIE Digital Library (Oct 5 2009) Gastroenterology

    Anatomical optical coherence tomography (aOCT) is a long-range, fibre-optic endoscopic imaging modality capable of quantifying the size and shape of the human airway lumen. This paper presents the first application of respiratory gating to 3D aOCT volumetric data. A sequence of time-gated data volumes are generated, characterising the dynamic behaviour of a segment of the lower airway over an averaged respiratory cycle. The technique is demonstrated on in vivo data ... (Read Full Article)

    The lymphatic system is a common route for the spread of cancer and the identification of lymph node metastases is a key task during cancer surgery. This paper demonstrates the use of optical coherence tomography to construct parametric images of lymph nodes. It describes a method to automatically estimate the optical attenuation coefficient of tissue. By mapping the optical attenuation coefficient at each location in the scan, it is possible ...
