Abstract
A system for ultrasound beamforming is provided, including a sampled analog beamformer, an array of ultrasound transducers, and a high voltage amplifier coupled to the sampled analog beamformer and the array of ultrasound transducers. The sampled analog beamformer includes a sampled analog filter for filtering an incoming analog signal and adding a fractional delay, and transmitting a filtered analog ultrasound signal. The array of ultrasound transducers further transmits the filtered analog ultrasound signal. The high voltage amplifier drives transducers in the array of ultrasound transducers.

A system for ultrasound beamforming, comprising:
- a sampled analog beamformer including a sampled analog filter for filtering an incoming analog signal and adding a fractional delay, and transmitting a filtered analog ultrasound signal;
- an array of ultrasound transducers for further transmitting the filtered analog ultrasound signal;
- and
- a high voltage amplifier coupled to the sampled analog beamformer and the array of ultrasound transducers configured to drive transducers in the array of ultrasound transducers.
A system for ultrasound beamforming comprising:
- an array of ultrasound transducers for receiving a reflected analog ultrasound signal;
- and
- a sampled analog beamformer coupled to the array of ultrasound transducers, the sampled analog beamformer for filtering the reflected analog ultrasound signal to form a sampled analog signal, and beamforming the sampled analog signal;
- wherein the sampled analog beamformer includes a summation node for adding the sampled analog signal to parallel sampled analog signals from parallel sampled analog beamformers.
A system for ultrasound beamforming, comprising:
- an array of ultrasound transducers for transmitting a filtered analog ultrasound signal and receiving a reflected analog ultrasound signal;
- and
- a sampled analog beamformer coupled to the array of ultrasound transducers, including means for filtering an incoming analog signal, adding a fractional delay, and transmitting the filtered analog ultrasound signal to the array of transducers, and for filtering the reflected analog ultrasound signal to form a sampled analog signal and beamforming the sampled analog signal.
