Abstract: The present disclosure relates to an ultrasound system comprising: an ultrasound transducer configured to transmit a plurality of ultrasound signals from a plurality of elements in a transducer array to a region of interest; the ultrasound transducer further configured to receive and sample a plurality of backscattered ultrasound signals from the region of interest; a processing unit configured to: calculate a local phase parameter in the time-domain for each of the plurality of backscattered ultrasound signals; calculate a center frequency for each of the local phase parameters of the backscattered ultrasound signals in the time domain; a beamformer configured to perform receiver beamforming by summing the center frequencies, wherein the ultrasound system is further configured to generate at least one parameter representative of a physical property of the region of interest based on the summed center frequencies. The disclosure further relates to ultrasound method for generating at least one parameter representative of a physical property of a region of interest.
