Design of Ultrasonic C-scan Imaging System Based on LabVIEW

This paper discusses current development state of domestic ultrasonic C-scan imaging system, which is generally more expensive and of high cost for its research and development. The authors have developed a new ultrasonic C-scan imaging system by using LabVIEW as the host computer together with ultrasound transmitting and receiving card and ordinary single chip STC89C51 to realize the flexible control of three-axis platform and efficient acquisition of the ultrasonic echo signal. So developed system improves the flexibility of the software, enhances the friendly operating software, and at the same time reduces the cost and promotes the water immersion ultrasonic C-scan automatic detection technology. The system can meet the requirements of plate of pressure-bearing equipment, forging and ultrasonic field measurement.
