    2. Integrated multimodality intravascular imaging system that combines optical coherence tomography, ultrasound imaging, and acoustic radiation force optical coherence elastography

      Integrated multimodality intravascular imaging system that combines optical coherence tomography, ultrasound imaging, and acoustic radiation force optical coherence elastography
      An integrated intraluminal imaging system includes an optical coherence tomography interferometer (OCT), an ultrasound subsystem (US) and a phase resolved acoustic radiation force optical coherence elastography subsystem (PR-RAF-OCE). The steps include performing OCT to generate a returned optical signal, performing US imaging to generate a returned ultrasound signal, performing PRARF-OCE to generate a returned PR-ARF-OCE signal by generating a amplitude modulated ultrasound beam or chirped amplitude modulated ultrasound beam to ...

    3. Imaging and quantifying Brownian motion of micro- and nanoparticles using phase-resolved Doppler variance optical coherence tomography

      Imaging and quantifying Brownian motion of micro- and nanoparticles using phase-resolved Doppler variance optical coherence tomography
      Different types and sizes of micro- and nanoparticles have been synthesized and developed for numerous applications. It is crucial to characterize the particle sizes. Traditional dynamic light scattering, a predominant method used to characterize particle size, is unable to provide depth resolved information or imaging functions. Doppler variance optical coherence tomography (OCT) measures the spectral bandwidth of the Doppler frequency shift due to the Brownian motion of the particles utilizing ...

    5. Phase-resolved acoustic radiation force optical coherence elastography

      Phase-resolved acoustic radiation force optical coherence elastography
      Many diseases involve changes in the biomechanical properties of tissue, and there is a close correlation between tissue elasticity and pathology. We report on the development of a phase-resolved acoustic radiation force optical coherence elastography method (ARF-OCE) to evaluate the elastic properties of tissue. This method utilizes chirped acoustic radiation force to produce excitation along the samples axial direction, and it uses phase-resolved optical coherence tomography (OCT) to measure the ...

    6. Feature Of The Week 12/18/11: UC Irvine Demonstrates Functional Imaging of Vibrating Vocal Folds with a High Speed OCT and ODT system

      Feature Of The Week 12/18/11: UC Irvine Demonstrates Functional Imaging of Vibrating Vocal Folds with a High Speed OCT and ODT system
      Vocal fold vibration is vital in voice production and the correct pitch of speech. University of California Irvine researchers have developed a high speed functional optical coherence tomography (OCT) system with a center wavelength of 1050 nm and an imaging speed of 100,000 A-lines per second and demonstrated imaging of the vibration of an ex-vivo swine vocal fold. High quality vocal fold images during vibration was demonstrated at an ...
