ABSTRACT:
The invention includes a method and system for multiple transmit zone splicing in an ultrasound imaging system. Acoustic signals from a pair of adjacent transmit zones are crossfaded in a region where the two transmit zones overlap (an "overlap region"), to produce a set of combined acoustic signals that transition from one transmit zone to the next with little or no delineation between transmit zones. The crossfade is linear and for the entire overlap region; however, the crossfade may alternatively employ a nonlinear function, or may encompass regions near to the overlap region. When a scan line comprises more than two transmit zones, pairs of transmit zones are crossfaded, preferably at each overlap region. When overlap regions are close to each other, a crossfade employing more than two transmit zones may be employed, such as a linear crossfade in which acoustic signals from three or more transmit zones are weighted and summed.
