1. A method for correcting beamforming time delays between at least two receive signals acquired in an ultrasound system, the method comprising: acquiring with an ultrasound transducer at least two receive signals; summing the at least two real receive signals received by transducer elements in the ultrasound system to form a reference signal using a summer; transforming the reference signal into a complex analytic signal using a complex filter; estimating a time delay error for each real receive signal by comparing the complex analytic signal and the corresponding real receive signal using a correlator processor; and correcting the beamforming time delays using the estimated time delay errors to generate an enhanced image.
