Ultrasound imaging using c-wave beams for increasing frame rate and signal strength

A method of acquiring ultrasound radio-frequency (RF) data using C-wave beams, comprising:

• providing an ultrasound transducer, the ultrasound transducer including a plurality of elements acting as both transmitters and receivers;
• transmitting sound waves from the transmitters of the ultrasound transducer within a transmit aperture with transmitter time delays being programed in such a way that sound waves are the C-wave beams that bend inward on both edges in a C shape;
• and
• receiving the sound waves using the receivers of the ultrasound transducer,
• wherein the coherent wavefront includes a variable tilt angle and a variable apex, and the variable apex moves away from a center of the ultrasound transducer as the variable tilt angle increases in absolute value;
• wherein the variable apex is an acoustical energy focusing center of the coherent wave;
• and
• wherein the variable tilt angle is an angle between a line connecting the center of an ellipse of the C-wave wavefront and the center of the ultrasound transducer and a vertical line passing the center of the ultrasound transducer.
