    2. Spectral 3D reconstruction of impressionist oil paintings based on macroscopic OCT imaging

      Spectral 3D reconstruction of impressionist oil paintings based on macroscopic OCT imaging
      Art conservators have adopted optical technologies to improve conservation efforts; laser triangulation, stereophotogrammetry, structured light, laser scanners, and time of flight sensors have been deployed to capture the 3D information of sculptures and architectures. Optical coherence tomography (OCT) has introduced new imaging methods to study the surface features and subsurface structures of delicate cultural heritage objects. However, the field of view of OCT severely limits the scanning area. We present ...

    3. Optical coherence tomography for non-invasive examination and conservation of cultural heritage objects

      Optical coherence tomography for non-invasive examination and conservation of cultural heritage objects
      Optical coherence tomography (OCT) has great potential for the examination of oil paintings, particularly for celebrated masterpieces by great artists in history. We developed an OCT system for large field of view (FOV), high definition (HD) imaging of oil paintings. To achieve large FOV, we translated the sample using a pair of high-precision linear motors and performed sequential volumetric imaging on adjacent, non-overlapping regions. Through 3D OCT imaging, the surface ...

    4. High-definition optical coherence tomography imaging for noninvasive examination of heritage works

      High-definition optical coherence tomography imaging for noninvasive examination of heritage works
      Cultural heritage works, such as ancient murals and historical paintings, are examined routinely for the purpose of conservation. Previous works have applied optical coherence tomography (OCT), which is a three-dimensional (3D) microscopic imaging modality in the field of heritage works conservation. The data acquired by OCT provides both 3D surface information of the object and structure information underneath the surface. Therefore, cross-sectional information on the object can be utilized to ...

    5. A three-parameter logistic model to characterize ovarian tissue using polarization-sensitive optical coherence tomography

      A three-parameter logistic model to characterize ovarian tissue using polarization-sensitive optical coherence tomography
      Wang, Tianheng; Yang, Yi; Zhu, QuingIn this paper, a logistic prediction model is introduced to characterize the ovarian tissue. A new parameter, the phase retardation rate, was extracted from phase images of polarization-sensitive optical coherence tomography (PS-OCT). Statistical significance of this parameter between normal and ... [Biomed. Opt. Express 4, 772-777 (2013)]

    6. Quantitative analysis of angle-resolved scattering properties of ovarian tissue using optical coherence tomography

      Quantitative analysis of angle-resolved scattering properties of ovarian tissue using optical coherence tomography
      Angle-resolved optical scattering properties of ovarian tissue, on different optical coherence tomography (OCT) imaging planes, were quantitatively measured by fitting the compounded OCT A-lines into a single scattering model. Higher cross correlation value of angle-resolved scattering coefficients between different OCT imaging planes was found in normal ovaries than was present in malignant ovaries. The mean cross correlation coefficient (MCC) was introduced in this pilot study to characterize and differentiate normal ...

    7. Assessment of collagen changes in ovarian tissue by extracting optical scattering coefficient from OCT images

      Assessment of collagen changes in ovarian tissue by extracting optical scattering coefficient from OCT images
      Optical scattering coefficient from ex-vivo unfixed normal and malignant ovarian tissue was quantitatively extracted by fitting optical coherence tomography (OCT) A-line signals to a single scattering model. 1097 average A-line measurements at a wavelength of 1310nm were performed at 108 sites obtained from 18 ovaries. The average scattering coefficient obtained from normal group consisted of 833 measurements from 88 sites was 2.41 mm-1 (±0.59), while the average coefficient ...

    8. Feature Of The Week 10/23/11: Hybrid Intraoperative Probe Based on OCT and Positron Detection for Ovarian Cancer Detection

      Feature Of The Week 10/23/11: Hybrid Intraoperative Probe Based on OCT and Positron Detection for Ovarian Cancer Detection
      Multi-modality imaging involving OCT and one or more additional imaging technologies continues to show very promising results for increasing the diagnostic and interventional guidance capability of biomedical imaging probes. These synergistic effects have been published in numerous papers over the past year. This includes OCT in combination with fluorescence, Raman, NIR, ultrasound, and other technologies. Such approaches have the obvious disadvantage of increasing the cost and complexity of the imaging ...
