Abstract
A medical ultrasonic imaging method uses transmitted plane waves, or transmitted wavefronts that are substantially planar, to improve contrast agent imaging by generating peak pressures that are more uniform over depth. Depending on the type of contrast agent, the returned frequencies of interest, and the desired strength of the non-linear response, multiple wavefronts can be generated at substantially the same time to increase peak pressures.
