ABSTRACT:
A method for correcting a time delay between at least two signals in ultrasound systems is provided. The ultrasound system comprises a beamformer processor comprising a summer coupled to the transducer array and configured for performing a complex operation on a first plurality of receive signals to generate a beamsum signal; wherein each of the receive signals comprise a corresponding beamforming delay and a complex filter coupled to the summer and configured to transform the beamsum signal to an analytical signal. The beamformer processor further comprises a plurality of correlator processors coupled to at least one respective transducer element and the complex filter, each correlator processor configured to calculate a correlation sum for at least one receive signal and at least one time delay estimator adapted to receive the correlation sum of at least one receive signal and configured to estimate the corresponding time delay using the correlation sum.
