  3. An automatic algorithm for detecting stent endothelialization from volumetric optical coherence tomography datasets

    Explore Article Institute of Physics (May 20 2008) Cardiology

    Recent research has suggested that endothelialization of vascular stents is crucial to reducing the risk of late stent thrombosis. With a resolution of approximately 10 µm, optical coherence tomography (OCT) may be an appropriate imaging modality for visualizing the vascular response to a stent and measuring the percentage of struts covered with an anti-thrombogenic cellular lining. We developed an image analysis program to locate covered and uncovered stent struts in ... (Read Full Article)

  4. Analog CMOS Design for Optical Coherence Tomography Signal Detection and Processing

    Explore Article IEEE Xplore (Feb 14 2008)

    A CMOS circuit was designed and fabricated for optical coherence tomography (OCT) signal detection and processing. The circuit includes a photoreceiver, differential gain stage and lock-in amplifier based demodulator. The photoreceiver consists of a CMOS photodetector and low noise differential transimpedance amplifier which converts the optical interference signal into a voltage. The differential gain stage further amplifies the signal. The in-phase and quadrature channels of the lock-in amplifier each include ... (Read Full Article)

    Alexandre R. Tumlinson, Bernd Hofer, Amy M. Winkler, Boris Považay, Wolfgang Drexler, Jennifer K. Barton. Depth dependent broadening of the axial point spread function due to dispersion in the imaged media, and algorithms for postprocess correction, have been previously described for both time domain and frequency domain optical coherence tomography. We show that homogeneous media dispersion artifacts ... [Appl. Opt. 47, 687-693 (2008)] (Read Full Article)

    Garret T. Bonnema, Kristen O. Cardinal, Stuart K. Williams et al. An ideal vascular stent design promotes a thin anti-thrombogenic cellular lining while avoiding restenosis. To assess the utility of their designs, stent manufactures often use destructive techniques such as scanning electron microscopy to measure the percentage of the stent covered with a cellular ...

  9. In vivo bidirectional color Doppler flow imaging of picoliter blood volumes using optical coherence tomography.

    Explore Article NCBI HomePage (Jan 15 2008) Cardiology , Ophthalmology

    We describe a novel optical system for bidirectional color Doppler imaging of flow in biological tissues with micrometer-scale resolution and demonstrate its use for in vivo imaging of blood flow in an animal model. Our technique, color Doppler optical coherence tomography (CDOCT), performs spatially localized optical Doppler velocimetry by use of scanning low-coherence interferometry. CDOCT is an extension of optical coherence tomography (OCT), employing coherent signal-acquisition electronics and joint time-frequency ... (Read Full Article)

  11. Methods of enhanced light transmission through turbid biological media

    Explore Article PatFT » Page 1 of 1 (Aug 14 2001) Patents

    A new process to increase light transmission in biological tissue has been developed. The technique involves temporarily replacing tissue water with a fluid that has a refractive index closer to that of inter/intra cellular components. Subsequently, the amount of index mis-match between these components and the fluid environment is temporarily decreased. This lowers the amount of random reflection and refraction which also reduces light scattering. In addition, the infrared absorption ... (Read Full Article)
