We investigate optical coherence elastography with micro-scale resolution using acoustic radiation force.
Viscoelastic tissue is assumed as Kelvin-Voigt model using a spring and a dashpot with elastic modulus and coefficient of viscosity.
Stress is caused in the tissue with the use of acoustic radiation force which is induced by a difference of acoustic energy density at the interface of the propagating media. The deformation of the tissue sample is measured by the swept source optical coherence tomography with the depth scanning rate of 20~kHz and the depth resolution of 9~$\muup$m. The displacement and the strain are calculated with the cross-correlation detection using the images before and after applying the force. The strain is slowly relaxed after removal of the force, and the time-varying curve is theoretically-modeled. We demonstrated the measurement and the imaging of viscoelastic characteristics. |
