基于现场可编程门阵列的高通量可级联超声成像系统的设计与实现
Design and implementation of high-throughput cascaded ultrasound imaging system based on field programmable gate array
摘要
Abstract
For high-throughput imaging applications such as three-dimensional cardiac imaging,we proposed a high-throughput,cascaded ultrasound imaging system based on field programmable gate array(FPGA).Firstly,a modular 256-channel PCIe FPGA ul-trasound hardware platform was developed,together with a synchronized"one-master three-slave"cascaded architecture to ensure cir-cuit reliability and cross-board timing synchronization.Then,for high-speed links,a LVDS data-processing method with adaptive tim-ing training and an AXI-bus-based FPGA transmission mechanism were designed to achieve robust multi-channel data alignment,buffering,and high-speed uplink transmission.Experimental results demonstrated that the power supply of this system was stable and effective.The system reliably supported transmit/receive operation with a 5 MHz center frequency,±70 V high-voltage pulses at a pulse repetition frequency of 2 kHz.The DDR4 buffering bandwidth≥8 GB/s,and the PCIe transfer bandwidth≥5 GB/s.Integrated transmit-receive tests using a cardiovascular phantom system showed clear echo signals.The system can provide a feasible low-power hardware solution and real-time data-processing platform for high-throughput ultrasound imaging,with promising application potential.关键词
