Abstract
A method and system for contrast agent image beamformation is provided. The acoustic energy of transmit beams is spread laterally to reduce contrast agent destruction. For example, a smaller aperture is provided for contrast agent imaging than for a default imaging mode. As another example, an apodization profile with a low amplitude for edge elements for contrast agent imaging is used as compared to the edge elements for a default imaging mode. As yet another example, the focal point used for contrast agent imaging is set to be outside of the region of interest (e.g. a shallow or deep focal point).
