1. A method for demodulating ultrasound data, the method comprising:
- receiving ultrasound data from a plurality of channels of an ultrasound probe in an ultrasound system;
reducing a sample rate of the received ultrasound data for the plurality of channels using digital demodulation, wherein a demodulation frequency for at least one of the plurality of channels is different than a demodulation frequency for at least one other of the plurality of channels;
communicating the reduced sample rate ultrasound data to a processor of the ultrasound system; and
performing processing of the reduced sample rate ultrasound data using the processor, wherein the processing includes beamforming.

Abstract
Methods and systems for controlling communication of data in an ultrasound system are provided. One method includes receiving ultrasound data from a plurality of channels of an ultrasound probe in an ultrasound system and digitally demodulating the received ultrasound data such that a data transfer rate of the digitally demodulated ultrasound data is lower than a data transfer rate of the received ultrasound data before digital demodulation. The method further includes processing the digitally demodulated ultrasound data, wherein the processing is performed using a processor of the ultrasound system.
