  • Patent number: 11883182
    Abstract: A system and a method is provided for assessing motion of a biological tissue of a subject including one or more superficial biological layers and a targeted biological layer. An optical perturbation is introduced within the one or more superficial biological layers but not within the targeted biological layer. A set of optical signal data is acquired preceding, during, or following the optical perturbation and, using the set of optical signal data, a set of optical characteristics is determined that is representative of light transiting the biological layers. Using the set of optical characteristics and a model of the biological layers, a target optical signal consistent with a target biological layer is separated and a movement of the desired biological tissue is determined using the target optical signal.
    Type: Grant
