%X Phase coherence between RF transmitter and receiver in digital MRI spectrometer was studied.In order to keep phase coherence between the transmitter and the receiver,we implemented a method in which the frequencies of the transmitter and the receiver were switched simultaneously during pulse sequence execution,and reset to their original values,respectively,at the end of sequence.The experimental results showed that this method is suitable for digital spectrometer and independent on the structure of transmitter and receiver.
