摘要: 该研究提出了一种集成式数字化磁共振成像谱仪。该谱仪使用FPGA芯片Artix7 200T,将时序控制、数据处理以及数字变频、相位精确控制功能集成到单片FPGA上,从而有效地提高了时序精度和相位精度,同时避免了多板总线连接方式造成的结构设计复杂,提高了系统集成度和成像质量。Abstract: An integrated digital magnetic resonance imaging spectrometer was proposed in this study. By using the FPGA chip Artix7 200T, timing control, data processing, digital frequency conversion and phase control were implemented into a single-chip, thus effectively improved timing accuracy and phase accuracy, while avoided the structural design complexity caused by multi-board connection and improved system integration and imaging quality.
