Ultrasonic Phased Array Detection System Based on PCIE Bus

This paper presents an ultrasonic phased array testing system based on PCIE bus. The workflow and functional blocks of the system are discussed. Special attention is paid to the key technologies such as array probe, ultrasonic transmit and receive path, data buffering and image reconstruction. The feasibility of the design has been verified through theoretical calculations，numerical simulations and experiments. It can be used as a reference for system’s realization.
