2. Measurement of vibrations induced on the surface of crystalline eye lens using PhS-SDOCT

   Explore Article SPIE Digital Library (Mar 2 2010) Ophthalmology

   Experimental assessment of stiffness of crystalline lens of the eye can help in understanding several ocular diseases. Studies have shown that stiffness of the eye lens increases with age that might contribute to loss of accommodation. The stiffness of the lens could be assessed by measuring mechanically induced surface waves propagating on its surface. Here we present preliminary results on phase sensitive spectral domain optical coherence tomography (PhS-SDOCT) measurements of ... (Read Full Article)

3. OCT monitoring of diffusion of water and glycerol through tooth dentine in different geometry of wetting

   Explore Article SPIE Digital Library (Feb 25 2010) Dentistry

   In our previous work optical coherence tomography (OCT) has been proved to be a useful tool for monitoring of diffusion of chemical agents (water, glycerol) within human tooth dentine. Such diffusion studies are interesting for tooth therapy (diffusion of medicinal preparations) and cosmetics (chemical whitening agents). Here we compare different wetting schemes in which the sample is either merged in the liquid agent so that the probe beam is to ... (Read Full Article)

   Topical trans-dermal delivery of drugs has proven to be a promising route for treatment of many dermatological diseases. The aim of this study is to monitor and quantify the permeability rate of glucose solutions in rhesus monkey skin noninvasively in vivo as a primate model for drug diffusion. A time-domain Optical Coherence Tomography (OCT) system was used to image the diffusion of glucose in the skin of anesthetized monkeys for ... (Read Full Article)

6. OCT monitoring of diffusion of clearing agents within tooth dentin

   Explore Article SPIE Digital Library (Sep 2 2009) Dentistry

   Monitoring of agent diffusion within tooth tissues is important in a wide context of tooth therapy (diffusion of medicinal preparations) and cosmetics (chemical whitening agents). We report here the results of optical coherence tomography (OCT) monitoring of diffusion of water and glycerol as clearing agents in samples of human tooth tissue. The diffusion process is analyzed by monitoring the changes in the OCT signal slope and the depth-resolved amplitude of ... (Read Full Article)

9. Phase-sensitive swept source optical coherence tomography for imaging and quantifying of microbubbles in clear and scattering media

   Explore Article Scitation (May 20 2009)

   phase resolved system based on swept source optical coherence tomography (SSOCT) called as phase-sensitive SSOCT to detect and quantify gas microbubbles in aqueous and tissue simulated media is developed. The structural images of gas microbubbles are obtained using conventional SSOCT, while common path SSOCT was used to perform the phase-sensitive measurements. The system shows an axial resolution of 10 µm, a phase sensitivity of 0.03 rad, an imaging depth of ... (Read Full Article)

    Explore Article ScienceDirect (Jun 17 2008)

    In this study, optical coherence tomography (OCT) was utilized in the functional imaging of glucose diffusion through scleral tissues. Permeability coefficients for different concentrations of glucose were quantified nondestructively. Obtained results indicate an inverse proportionality between the permeability coefficient and the concentration of the analyte in epithelial tissues: in-depth diffusion of solutions with lower glucose concentration was faster than those with a higher concentration. The permeability coefficient decreased from (1.67±0.17)×10−5 ... (Read Full Article)
