摘要: 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.

摘要: Systems and methods are provided for volumetric analysis of pathologies. A segmentation component is configured to determine, for each of a series of images of a region of interest containing a pathological feature, a set of segmentation boundaries within the image representing a cross-section of the pathological feature. A mesh generation component is configured to link the sets of segmentation boundaries from adjacent images in the series of images to generate a polygonal mesh representing a volumetric reconstruction of the pathological feature. A volumetric measurement component is configured to calculate volumetric parameters from the volumetric reconstruction representing the pathological feature. A user interface is configured to provide the calculated volumetric parameters to an associated display.

摘要: Systems and method are provided for evaluating a biomechanical property of tissue. A shear wave generator induces a shear wave in the tissue. An optical imaging system captures video in the visible light spectrum comprising a series of image frames of the tissue during the shear wave. An image processing component determines, at each of a plurality of locations, a speed at which the shear wave travels within the tissue from the series of image frames. A parameter calculation component calculates a value for the biomechanical property from the determined speed of the shear wave at a plural subset of the plurality of locations.
