Elastic wave imaging optical coherence elastography (EWI-OCE) is an emerging technique that can quantify local
biomechanical properties of tissues. However, long acquisition times make this technique unfeasible for clinical use.
Here, we demonstrate a noncontact single shot line-field OCE technique using a line-field interferometer and an air-pulse
delivery system. The spatial-temporal elastic wave propagation profile was acquired in a single shot and used
to quantify the elastic wave group velocity in tissue. Results on tissue-mimicking phantoms and chicken breast
muscle agreed well with mechanical compression testing, demonstrating that the presented method can effectively
reduce the OCE acquisition time to a few milliseconds in biological application.
Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
