Abstract:
Nonlinear ultrasound imaging systems and methods are disclose. In one aspect, a nonlinear ultrasound imaging system includes a first transducer configured to transmit a first ultrasound signal along a scan line, a second transducer configured to sweep a second ultrasound signal along the scan line such that the first and second ultrasound signals intersect at a plurality of voxels, and a third transducer configured to receive echoes associated with interactions of the first and second ultrasound signals at the plurality of voxels. The nonlinear ultrasound imaging system further includes a processor configured to generate an ultrasound image based on the echoes.

Claim (Index 1):
A method of nonlinear ultrasound imaging, the method comprising:\n transmitting, with a first transducer, a first ultrasound signal centered at a first frequency; transmitting, with a second transducer, a second ultrasound signal centered at a second frequency, wherein transmitting the second ultrasound signal comprises sweeping the second ultrasound signal in a direction such that the second ultrasound signal intersects with the first ultrasound signal at a plurality of voxels along a scan line as the first ultrasound signal propagates along the scan line, wherein the second frequency is different than the first frequency; receiving, with a third transducer, echoes associated with interaction of the first ultrasound signal and the second ultrasound signal in the voxels along the scan line, wherein the echoes are centered at a third frequency that is based on the first frequency of the first ultrasound signal and the second frequency of the second ultrasound signal; processing the echoes associated with interaction of the first ultrasound signal and the second ultrasound signal in the voxels along the scan line; and generating an ultrasound image based on the processing.
