Matrix Array Transducers for Volume Imaging
Matrix Arrays are a leading-edge transducer technology that enable ultrafast acquisition of volume data. Utilizing 1024 elements in a 32×32 grid, and available in 3 and 8 MHz models, these transducers are compatible with the Vantage NXT and Vantage 256-channel Research Ultrasound Systems. Verasonics provides example scripts for multiplexed acquisition sequences using a single 256-channel system, as well as scripts for direct acquisition with four 256-channel systems for one-to-one channel-to-element connections.

Verasonics UTA 1024-MUX Adapter
Verasonics’ Universal Transducer Adapter (UTA) allows Vantage systems to operate matrix array transducers through a unique small format connector. The MUX switch topology allows for switching apertures between transmit and receive, and for connecting each channel to up to four elements in parallel, and permits particular types of transmissions using larger apertures (e.g. plane wave).
