摘要:
提出一种保持磁共振谱仪射频发射单元和谱仪射频接收单元之间相位相干的实现方案。方法:基于美国National Instruments公司的高性能工控机平台,通过LabVIEW软件的图形化界面完成软件对硬件的控制。结果:除了评估成像图像的信噪比之外,还评估了扫描图像的对比度,这两项指标都满足磁共振成像需求。结论:从成像图像信噪比和对比度两方面验证了本研究设计的功能满足成像要求。
Abstract:
Objective To propose an implementation scheme for maintaining the phase coherence between radiofrequency transmitter and radiofrequency receiver of magnetic resonance spectrometer. Methods Based on the high-performance industrial control computer platform of National Instruments, the hardware was controlled by software through the graphical interface of LabVIEW software. Results Both signal-to-noise ratio and contrast-to-noise ratio of the obtained image met the requirements for magnetic resonance imaging. Conclusion The function designed in the study is verified to satisfy the imaging requirements from the aspects of image signal-to-noise ratio and contrast-to-noise ratio.
