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