    2. Multimodality Cardiovascular Molecular Imaging Technology

      Multimodality Cardiovascular Molecular Imaging Technology
      Cardiovascular molecular imaging is a new discipline that integrates scientific advances in both functional imaging and molecular probes to improve our understanding of the molecular basis of the cardiovascular system. These advances are driven by in vivo imaging of molecular processes in animals, usually small animals, and are rapidly moving toward clinical applications. Molecular imaging has the potential to revolutionize the diagnosis and treatment of cardiovascular disease. The 2 key ...

    3. Optical fiber scanner for performing multimodal optical imaging

      An optical fiber scanner is used for multiphoton excitation imaging, optical coherence tomography, or for confocal imaging in which transverse scans are carried out at a plurality of successively different depths within tissue. The optical fiber scanner is implemented as a scanning endoscope using a cantilevered optical fiber that is driven into resonance or near resonance by an actuator. The actuator is energized with drive signals that cause the optical ...

    5. High-resolution OCT balloon imaging catheter with astigmatism correction

      High-resolution OCT balloon imaging catheter with astigmatism correction
      We report new optics designs for an optical coherence tomography (OCT) balloon imaging catheter to achieve diffraction-limited high resolution at a large working distance and enable the correction of severe astigmatism in the catheter. The designs employed a 1 mm diameter gradient-index lens of a properly chosen pitch number and a glass rod spacer to fully utilize the available NA of the miniature optics. Astigmatism caused by the balloon tubing ...

    6. Tethered capsule endoscope for Barrett's Esophagus screening

      A capsule is coupled to a tether that is manipulated to position the capsule and a scanner included within the capsule at a desired location within a lumen in a patient's body. Images produced by the scanner can be used to detect Barrett's Esophagus (BE) and early (asymptomatic) esophageal cancer after the capsule is swallowed and positioned with the tether to enable the scanner in the capsule to ...

    7. Electromagnetic Coherent Tomography Array Imaging in Random Scattering Media

      Imaging through discrete random media is an important problem in several applications such as medicine, remote sensing, and security. Discrete random media create scattering which deteriorates the quality of the image and there have been several efforts to mitigate the problem. We propose an array processing method called coherence tomography array (CTA) whose algorithm is derived from that of optical coherence tomography. We use the Monte Carlo method to simulate ...

    8. In Situ Characterization of the Degradation of PLGA Microspheres in Hyaluronic Acid Hydrogels by Optical Coherence Tomography

      The polymeric implant material poly(lactide-co-glycolide) (PLGA) degrades by a process of bulk degradation, which allows it to be used for the controlled release of therapeutic molecules from implants and microspheres. The temporal characterization of PLGA microsphere degradation has been limited by the need to destructively monitor the samples at each time point. In this study, a noninvasive imaging technology, optical coherence tomography (OCT), was utilized to characterize the in ...

    9. Flexible miniature compound lens design for high-resolution optical coherence tomography balloon imaging catheter

      We report on a new optics design for an optical coherence tomography (OCT) balloon imaging catheter. The design involves a miniature compound gradient-index (GRIN) rod lens, which consists of a fiber optic mode-field reducer and relay rod lenses to achieve predictable high lateral resolution at a desired large working distance. The compound lens design significantly simplifies the engineering process for an OCT catheter and enables 3-D full circumferential cross sectional ...

    11. In Situ Ultrahigh-resolution Optical Coherence Tomography Characterization of Eye Bank Corneal Tissue Processed for Lamellar Keratoplasty.

      Purpose: To use optical coherence tomography (OCT) as a noninvasive tool to perform in situ characterization of eye bank corneal tissue processed for lamellar keratoplasty. Methods: A custom-built ultrahigh-resolution OCT (UHR-OCT) was used to characterize donor corneal tissue that had been processed for lamellar keratoplasty. Twenty-seven donor corneas were analyzed. Four donor corneas were used as controls, whereas the rest were processed into donor corneal buttons for lamellar transplantation by ...

  2. About University of Washington

    University of Washington

    The University of Washington, founded in 1861, is a public research university in Seattle, Washington, United States. It is the largest university in the Northwestern United States and the oldest public university in Washington. The UW maintains three locations, with its flagship campus in Seattle's University District and branch campuses in Tacoma and Bothell. Its operating budget for fiscal year 2005 was $3.1 billion. The university is known as a Public Ivy, an American term for state-funded institutions of higher learning that "provide[s] an Ivy League collegiate experience at a public school price."
