摘要：
Methods, systems and computer program products for determining a mechanical parameter for a sample having a target region, include determining a prior probability density function that characterizes at least one physical property of the target region； generating a displacement of the sample in the target region to form a shear wave that propagates orthogonal to a direction of the displacement； transmitting tracking pulses in the target region； receiving corresponding echo signals for the tracking pulses in the target region at a plurality of lateral positions； estimating a propagation parameter of the shear wave in response to the echo signals and the prior probability density function using statistical inference； and determining at least one mechanical parameter of the target region based on the estimated propagation parameter.
