Abstract
Receive signals generated by ultrasound waves propagating in completed manner in a depth direction of a subject, are efficiently subjected to delay-and-sum processing, whereby a higher resolution image is generated with reducing a circuit size. Receive signals outputted from multiple ultrasound probe elements are delayed by predetermined delay amounts in association with the depths of receive focal points, respectively, and the delayed receive signal is branched. The phase of the branched receive signal is shifted by a predetermined phase shift amount to generate a phase-compensated signal, and then the phase-compensated signal is added to the receive signal before branched, thereby generating a beamformed signal.
