Measurements of biomechanics by dynamic optical coherence elastography

The measurements of biomechanics by dynamic optical coherence elastography (OCE) has been reported This technique has great potential for detecting mechanical property changes in the tissue microstructure such as tumor invasion due to its high resolution, high speed and non-invasive features. OCE techniques can be classified as static or dynamic depending on the mechanical excitation approach used. Novel dynamic OCE imaging techniques, including external and internal excitation methods, have been applied quantitatively for measuring and mapping biomechanical properties of tissue phantoms and biological tissues. OCE technologies have the potential to be used to identify and quantify mechanical tissue properties in various biomedical applications such as early stage tumor detection.
