基于SerialLite Ⅱ协议的磁共振采集数据传输系统设计OACSTPCD

Magnetic resonance imaging(MRI)is a non-invasive technology for detecting the internal structure of human body.As the number of receiving channels increases,the amount of collected data generated increases,which brings huge challenges to rapid imaging.A magnetic resonance acquisition data transmission system based on the SerialLite Ⅱ protocol is designed.The system functions are mainly implemented by FPGA and are divided into data cache module and data transmission module.The data cache module is based on double buffer area and state machine controlled ping-pong operation,which effectively solves the problem of read and write conflicts caused by large data volume.The data transmission module is used to establish a SerialLite Ⅱ data transmission link based on FPGA,so as to realize optical fiber data transmission of collected data.The simulation and experiments verifies the correctness of the system functions,showing that it can achieve high-speed and stable transmission of magnetic resonance acquisition data.
