Abstract: Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.

Abstract: Ultrasound apparatus and methods of processing signals are described. The ultrasound apparatus may include multiple channels. In some embodiments, signal processing techniques are described, which in some embodiments are performed on a per-channel basis. The signal processing techniques may involve using down-conversion and filtering of signals on multiple channels. The down-conversion and filtering may be done prior to beamforming.
