Abstract
Certain embodiments include a system and method for improved compound imaging using a plurality of imaging modes. In an embodiment, a plurality of echo signals are received in response to a plurality of beams formed based on different imaging modes corresponding to different steering angles, such as steered or non-steered angles. The plurality of echo signals is compounded to form a compound image. In an embodiment, the imaging mode includes at least one of harmonic, fundamental, coded harmonic, and variable frequency imaging. Parameters may be generated for the plurality of beams formed based on different imaging modes corresponding to different steering angles. Additionally, the parameters may be stored. The echo signals may be filtered. Imaging mode may be controlled based on steering angle. Employing different imaging modes based on steering angles for spatial compound imaging helps reduce grating lobe artifacts while improving speckle reduction effect.
