Abstract
Multiline acquisition is used to acquire groups of beams in response to transmit pulses. At least some of the beams from spatially adjacent groups are coaxially aligned. The echo information is detected and coaxially aligned beams are blended together using weighting functions which vary as a function of the time and location of the blended beams from their transmit beam apertures to gradually blend the aligned beams together spatially, thereby reducing multiline image artifacts. Echoes from moving objects in coaxially aligned beams may be aligned axially before the beams are blended together.
