Acoustic velocity inhomogeneitis in tissue result in aberration of ultrasonic images. These aberrations can be modelled as a near field thin phase screen or as a distributed aberrator. Current techniques for the correction of distributed aberrators are limited to application on point targets. A new technique is proposed using multiple transmits from spatially shifted transmit apertures, called translating transmit apertures, which can remove the decorrelation of speckle with receiver position. Translating transmit apertures, when used in conjunction wit phase conjugate filters, can correct for distributed aberrations in the presence of speckle targets.
