Verasonics VANTAGE NXT 256 Research Ultrasound System

General Description: 

The Verasonics ultrasound system is laboratory research and/or development platform, and is intended to be used to acquire, store, display and analyze acoustic data for research purposes. A unique advantage of the system is its open access to multiple layers of raw data, distinguishing it from medical ultrasounds manufactured by major healthcare technology companies (e.g., Siemens, Philips, GE). This open access to raw data empowers us to obtain more accurate results for correlation-based image processing. Furthermore, the system's flexibility for NDE transducers and algorithms broadens its applications, facilitating non-optical feature/defect/crack detection in materials across various disciplines.

The Vantage NXT 256 System we plan to acquire includes 256 transmit and 256 receive channels. The system will be able to connect two 128-element linear array transducers to enable dual-plane simultaneous measurements for analysis of transient flow phenomena in both axial and cross-sectional planes. The system has a transmit and receive frequency range of 0.25 MHz to 24 MHz, and a time delay resolution of 2.0 nsec and a minimum pulse width of 4.0 nsec. The NXT series is the newest version of the Vantage systems, which has a capability of per-channel programming of tri-state transitions on a 2-ns grid. This allows the system to be programmed to generate arbitrary acoustic waveforms for varied research needs. The system will include Vantage NXT UTA 260D and NXT UTA 160-SI connectors for biomedical imaging and NDE transducers, respectively. The switch between these two research modes is easy and well-integrated in the software packages. The software installed on the host controller will allow us to fine-tune parameters, perform image reconstruction, and generate trigger signals for multi-device synchronization.
