Case Studies
Acoustic Micro-Imaging
THE PROBLEM
The customer is a leader in the field of acoustic micro-imaging. They use pulse ultrasound to image non-human materials. The ultrasound frequency used is between 100 and 200 MHz, as the materials they study can handle these frequencies (one cannot normally use such high frequencies with human tissue).
The customer's PRF (Pulse Repeat Frequency) is approximately 4 KHz, with a PRI (Pulse Repeat Interval) of 250 m s. They need to capture approximately 2 m s (1,000 points) of data for each pulse.
The customer is currently using Windows 95, but wants to begin programming under Windows NT in the future. The customer also wants scope emulation software to allow verification of board operation without having to write software.
GAGE'S SOLUTION
The CompuScope 8500 is ideal for this application. With a PCI throughput of 100 MB/s, the customer can easily transfer the captured data to the PC memory for each pulse and re-arm with plenty of time to spare (see the diagram).
Drivers for both Windows 95 and Windows NT are available for the CS8500. In addition, GageScope software will allow the customer to do exactly what they asked: verify the operation of the CompuScope 8500 without writing any code.
PRODUCT RECOMMENDED
CompuScope 8500
GageScope software
CompuScope Driver for Windows 95 or Windows NT
