Ultrasound systems with microbeamformers for different transducer arrays

An ultrasound microbeamformer for one or more transducer arrays includes a plurality of channels, each of which has two transmitters and a receiver which is selectively coupled to two or more transducer elements by T/R switches and dynamically switchable receive switches (RXSW). The transmitters ena...

Zusammenfassung:	An ultrasound microbeamformer for one or more transducer arrays includes a plurality of channels, each of which has two transmitters and a receiver which is selectively coupled to two or more transducer elements by T/R switches and dynamically switchable receive switches (RXSW). The transmitters enable different transducers to be actuated differently, such as transmitting a high frequency pulse or waveform with one transmitter and a low frequency pulse or waveform with the other transmitter. The transmitters may both be used during the same transmit-receive cycle to simultaneously transmit and receive both high and low frequency signals for the formation of a common image.
