Dynamic spectral-domain optical coherence elastography for tissue characterization
A dynamic spectral-domain optical coherence elastography (OCE) imaging technique is reported. In this technique, audio-frequency compressive vibrations are generated by a piezoelectric stack as external excitation, and strain rates in the sample are calculated and mapped quantitatively using phase-sensitive spectral-domain optical coherence tomography. At different driving frequencies, this tec...
متن کاملDynamic Optical Coherence Elastography: a Review.
With the development of optical coherence tomography, the application optical coherence elastography (OCE) has gained more and more attention in biomechanics for its unique features including micron-scale resolution, real-time processing, and non-invasive imaging. In this review, one group of OCE techniques, namely dynamic OCE, are introduced and discussed including external dynamic OCE mapping...
متن کاملSpectroscopic optical coherence elastography
We present an optical technique to image the frequency-dependent complex mechanical response of a viscoelastic sample. Three-dimensional hyperspectral data, comprising two-dimensional B-mode images and a third dimension corresponding to vibration frequency, were acquired from samples undergoing external mechanical excitation in the audio-frequency range. We describe the optical coherence tomogr...
متن کاملOptical coherence elastography of engineered and developing tissue.
Biomechanical elastic properties are among the many variables used to characterize in vivo and in vitro tissues. Since these properties depend largely on the micro- and macroscopic structural organization tissue, it is crucial to understand the mechanical properties and the alterations that occur tissues respond to external forces or to disease processes. Using a novel technique called coherenc...
متن کاملBiomechanical properties of soft tissue measurement using Optical Coherence Elastography
Optical Coherence Tomography (OCT) provides images at near histological resolution, which allows for the identification of micron sized morphological tissue structures. Optical coherence elastography (OCE) measures tissue displacement and utilizes the high resolution of OCT to generate high-resolution stiffness maps. In this work, we explored the potential of measuring shear wave propagation us...
