2. Applications of Doppler optical coherence tomography based on zero-crossing detection to flow monitoring inside a stenosis phantom

   Scitation (Aug 12 2008) Cardiology Explore Article

   Most of the time, arterial stenoses caused by atherosclerosis, hardening of the artery walls, or buildup of fatty deposits prevent the blood from flowing normally. Blood flow characteristics in the vicinity of a stenosis are therefore very important since the restriction may accelerate fatty deposits and thus quickly clog the artery. Doppler Optical Coherence Tomography (DOCT) is a biomedical technique that allows simultaneous structural imaging and flow monitoring inside biological ... (Read Full Article)

   Deformable and durable phantoms with controlled density of scatterers. Phys Med Biol. 2008 Jun 17;53(13):N237-N247 Authors: Bisaillon CE, Lamouche G, Maciejko R, Dufour M, Monchalin JP We have developed deformable and durable optical tissue phantoms with a simple and well-defined microstructure including a novel combination of scatterers and a matrix material. These were developed for speckle and elastography investigations in optical coherence tomography, but should prove useful in many other ... (Read Full Article)

5. A zero-crossing detection method applied to Doppler OCT

   opticsinfobase.org (Mar 17 2008) Explore Article

   Zhiqiang Xu, Lionel Carrion, Roman Maciejko. We present a numerical method based on the detection of the zero-crossing points in an OCT signal for the measurement of the Doppler frequency in a laminar flow. This method is compared to other processing approaches currently used in Doppler OCT. The results show that in the case of laminar ... [Opt. Express 16, 4394-4412 (2008)] (Read Full Article)

6. An assessment of the Wigner distribution method in Doppler OCT

   opticsinfobase.org (Oct 24 2007) Explore Article

   Analyzing the experimental data of the velocity distribution in a fluid flow using Doppler Optical Coherence Tomography (OCT), we compared the Wigner distribution method to the short-time Fourier transform method, the Hilbert-based phase-resolved method and the autocorrelation method. We conclude that the pseudo Wigner-distribution signal processing method is overall more precise than other often-used methods in Doppler OCT for the analysis of cross-sectional velocity distributions.
