    摘要： A device and a method for computing a weighted-average-based position of a shear wave in a temporal domain based on a sampling of shear wave displacements along a propagation path of the shear wave. The weighted-average-based position is, for example, by displacement observed at a plurality of times that correspond to sampling, and represents a time of arrival of the shear wave at a location being sampled along the propagation path. Further, times of arrival of the shear wave at respective locations along the propagation path are functionally related to known inter-location distances to derive shear-wave group velocity. The derived shear-wave group velocity serves as an input into algorithms for estimating a shear elasticity of a medium, such as a body tissue, for purposes of a clinical diagnosis and therapy assessment.

    摘要： An ultrasound system and method that identify flow regions within a volume. The system comprises: a survey system for collecting motion data from a target image; a segmentation system for mapping a region of flow within the image based on the motion data; and a flow acquisition system that automatically limits the collection of flow image data within the image to the region of flow.

    摘要： In some embodiments, a method and routing system parameterize a routing policy and apply the parameterized-routing policy to a route. Parameters are assigned to at least some policy statements of the policy. The parameterized policy may be called with parameters stored in a parameter table. In some embodiments, common blocks of the policy may be identified and assigned parameter sets. A commonized routing policy may be reused within more than one policy.In some embodiments, a method and routing system may evaluate a configuration file to determine relationships between route attributes. The relationships may be expressed in one or more mathematical functions, and when a route is received from a peer, the attributes of the route may be modified based on the mathematical functions.In some embodiments, a router and method for implementing routing policy and traffic engineering are provided. Routing policy may be implemented by performing a policy translation on a policy configuration to generate an internal-policy representation. Attribute-operator pairings of the internal-policy representation may be verified with one or more client dynamic load libraries (DLLs). When the attribute-operator pairings have been verified, the internal-policy representation may be compiled and stored in a system database. A client protocol may be notified that the routing policy has been modified.

    摘要： The weighted-average-based position (244) in the temporal domain is computed based on the sampling of shear wave displacement (226) along the propagation path. The weighting is, for example, by displacement observed at times (230) corresponding to sampling and represents the time of arrival of the shear wave at the shear-wave propagation path location being sampled. In some embodiments, the computed shear-wave times of arrival at respective locations are functionally related to known inter-location distances (250) to derive shear-wave group velocity. The derived velocity can serve as input into known algorithms for estimating shear elasticity of the medium, such as body tissue, for purposes of clinical diagnosis and therapy assessment.
