Abstract

The embodiment of the invention discloses a data and clock alignment method and device, medium and magnetic resonance equipment. The method is applied to an idle time interval for emitting two radio-frequency pulses and comprises the following steps that: receiving a data synchronous clock signal; according to a first clock, collecting the data synchronous clock signal, carrying out one-time time delay on the first clock for stepping after the synchronous clock signal is collected each time, and continuously collecting the synchronous clock signal according to the clock subjected to the time delay until the synchronous clock signals of at least one cycle is collected; according to the collected synchronous clock signals of at least one cycle, determining a time delay value; and according to the time delay value, carrying out time delay to obtain a second clock, and collecting the last one radio-frequency pulse signal in the two radio-frequency pulse signals. By use of the technical scheme, the dynamic alignment of the data and the clock can be realized, and alignment speed and a data input rate can be improved.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular to a method, device, medium and magnetic resonance equipment for aligning data and clocks. Background technique [0002] MR (Magnetic Resonance, nuclear magnetic resonance) equipment transmits radio frequency pulses to make magnetized protons absorb radio frequency energy to generate MR signals. The MR signal receiver receives the MR signals, processes them, and reconstructs them according to certain mathematical methods to generate MR images. During the MR imaging process, according to the requirements of the imaging method, the MR equipment generates multiple radio frequency pulse signals at a certain time interval. In a DAC (Digital to Analog Converter, digital-to-analog converter), in order to ensure the correctness of radio frequency pulse signal transmission, it is necessary to ensure that the radio frequency pulse signal is aligned with the clock. The...
