Abstract
Systems and method are provided for evaluating a biomechanical property of tissue. A shear wave generator is configured to induce a shear wave in the tissue. An optical coherence tomography (OCT) imager is configured to capture a B-scan frame of the tissue. An image processing component is configured to determine a frequency of the shear wave in the tissue from the B-scan frame of the tissue at each of a plurality of locations within the B-scan. A parameter calculation component is configured to calculate a value for the biomechanical property for a plural subset of the plurality of locations within the B-scan frame of the tissue from the determined frequency of the shear wave at each of the plural subset of the plurality of locations.
