Wireless Clock Synchronization Device and Method for Magnetic Resonance Imaging, and Magnetic Resonance Imaging System

A wireless clock synchronization device for magnetic resonance imaging, comprising:

• a system clock;
• a main controller;
• a radio-frequency carrier signal generator;
• a system clock signal modulator;
• and
• a first radio-frequency transmitter located at a magnetic resonance system end, wherein:
• the system clock is configured to generate a system clock signal and output the system clock signal to the system clock signal modulator;
• based on a radio-frequency carrier frequency adjustment timing determined according to a preset radio-frequency carrier frequency adjustment cycle arrives, the main controller is configured to determine a radio-frequency carrier frequency for a next cycle according to a current radio-frequency carrier frequency and a set radio-frequency carrier frequency adjustment step size, and send the radio-frequency carrier frequency for the next cycle to the radio-frequency carrier signal generator;
• the radio-frequency carrier signal generator is configured to generate a radio-frequency carrier signal of a corresponding frequency according to the radio-frequency carrier frequency for the next cycle, and sends the radio-frequency carrier signal to the system clock signal modulator;
• the system clock signal modulator is configured to modulate a system clock signal onto the radio-frequency carrier signal and emits the modulated radio-frequency signal;
• and
• the first radio-frequency transmitter is configured to emit the radio-frequency signal emitted from the system clock signal modulator.
