Verasonics Sync Module
One of the challenges in combining multiple systems for research or product development is the synchronization of transmit and receive clocks for each system. Verasonics has developed the Multi-System Synchronization Module that can synchronize up to 8 Vantage systems for a total of 2048 channels. The Multi-System Synchronization Module connects to each Vantage system with HDMI cables and the individual 250 MHz system clocks are synchronized to within 2ns.
The Multi-System Vantage configurations define one system as the primary, with one or more secondary systems. Identical scripts are run on each system and the sequences are synchronized using the input/output triggers. Using high-speed serial modules, raw volume data is transferred from each secondary system’s host controller to the primary computer at up to 4GB/s. To further accelerate data transfer and reconstruction processing, a pre-transfer beamforming mode can be enabled on each secondary computer. Data from all secondary system is collected in the primary system computer for final processing and display.
Experiments can be simulated using Vantage software before running the scripts on the Vantage hardware and transducer.
Verasonics’ Vantage Volume Software
Vantage software for acquisition and reconstruction of 3D imaging is part of the Vantage Volume solution. The Vantage software now includes several example scripts for basic volume imaging such as plane wave imaging (single angle for high frame rate imaging, and multiple angles for improved quality), and “wide beam” (weakly focused beams for high quality imaging). All will use the 1024-element MUX that permits switching apertures between transmit and receive, and connecting up to 4 elements in parallel during transmit to speed up synthetic aperture imaging using special beam patterns.
