Abstract
Methods and systems for ultrasound imaging are presented. The method includes configuring a plurality of apertures in a transducer array of an ultrasound imaging device, where the apertures include one or more transducer elements. Further, one or more reference pulses are delivered to a plurality of target regions to detect corresponding initial positions. Additionally, a pushing pulse is delivered to at least two of the plurality of target regions through at least two of the plurality of apertures. The plurality of apertures is focused at specific target regions in the plurality of target regions using a compound delay profile. Subsequently, one or more tracking pulses are delivered to the plurality of target regions for detecting corresponding displacements of at least the specific target regions. Further, ultrasound imaging methods that deliver a plurality of short pushing pulse segments and/or tracking pulses to corresponding target regions in an interleaving manner are described.
