We demonstrate a novel method for noninvasive elasticity mapping in three dimensions using phase stabilized swept source optical coherence elastography (PhS-SSOCE). By calculating the velocity in all radial directions from the origin of the induced shear wave, a volumetric elasticity map of the sample was generated. Due to the submicrometer spatial sensitivity of PhS-SSOCE, the loading force and the induced deformation amplitude can be minimal, thus preserving the structure and function of delicate tissues such as the cornea and sclera of the eye. Tissue mimicking agar phantoms were utilized for proof of concept testing and the results show that this method can noninvasively provide a three dimensional estimation of sample elasticity.
