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.
