Abstract
Nonlinear ultrasound imaging techniques that send ultrasound transmissions with multiple frequency or phase cycles for exciting and imaging nonlinear scatterers such as acoustic biomolecules.
Claims25
An ultrasound imaging system comprising:
- an arrangement of transducer elements;
- and
- a plurality of apertures of different sets of transducer elements in the arrangement of transducer elements, wherein each transducer element of each aperture is configured to generate an acoustic wave when activated by a transmission signal having a plurality of cycles, wherein acoustic waves generated by each set of transducer elements of each aperture form an acoustic beam along an axis;
- wherein the arrangement of transducer elements is configured to generate a received signal based on backscatter echo detected in response to the acoustic beam.
