    1. Assessment of arterial characteristics in human atherosclerosis by extracting optical properties from polarization-sensitive optical coherence tomography

      In this research, we assessed arterial characteristics in human atherosclerosis by determining both scattering and birefringence properties of vessel tissue from polarization-sensitive optical coherence tomography (PS-OCT) images. We demonstrated that optical characteristics ... [Opt. Express 16, 8117-8125 (2008)]

    2. Quantitative analysis on optical properties of human atherosclerosis by using polarization-sensitive optical coherence tomography

      Wen-Chuan Kuo, Ming-Wei Hsiung, Jeou-Jong Shyu et al. In this research, we have used an algorithm to extract four different optical parameters, including the scattering coefficient ([mu]), effective anisotropy factor (g), birefringence coefficient (Deltan), and fast-axis angle (beta) from polarization-sensitive optical coherence tomography (PS-OCT) ima ...

    3. Extraction of Quantitative Optical Properties from Polarization-sensitive Optical Coherence Tomography

      In this research, we have developed an algorithm to extract four different optical parameters including the scattering coefficient (∆s), effective anisotropy factor (geff), birefringence coefficient (∆n), and fast-axis angle (β) from polarization-sensitive optical coherence tomography (PS-OCT) images. The proposed extraction algorithm was evaluated from a set of phantoms and it yielded valid results. The scattering coefficient and anisotropy factor can be used to describe the scattering effect and anisotropy characteristics of the sample. The birefringence property represents the difference between the tissue refractive indexes along the birefringent fast and slow axes, while the fast-axis angle can describe the fiber alignment ...
