摘要：
The ultrasound system includes a controller configured to communicate with an ultrasound transducer such that the ultrasound transducer emits a radiation force excitation ultrasound pulse from the ultrasound transducer that propagates through the region of interest and is sufficient to perturb a fluid in the region of interest emits a first and second acoustic ultrasound pulse from the ultrasound transducer that propagates away from the ultrasound transducer, through a region of interest and produces respective first and second echo ultrasound signal that propagate from the region of interest to the ultrasound transducer and receives a first and second data set responsive to the first and second respective echo signals at the ultrasound transducer. A decorrelation module is configured to identify a decorrelation region of decorrelated data that is decorrelated between the first and second data sets, and the decorrelation region indicates a presence of fluid in the region of interest.
