Abstract: Systems and methods for data transmission may be provided. The system may at least include a data transmission module. The system may obtain MR signals from one or more RF coils. The system may generate, via a first portion of the data transmitting module, first data based on the MR signals. The system may generate, via a second portion of the data transmitting module, second data based on the first data. The second portion of the data transmitting module may connect to the first portion of the data transmitting module wirelessly. The system may further store the second data in a non-transitory computer-readable storage medium.

Abstract: Systems and methods for MR siganal synchronization may be provided. The method may include determining a time difference in a local clock generator at a coil side assembly compared to a system clock generator at a system side assembly. The method may include maintaining a constant phase difference between clock signals generated by the local clock generator and by the system clock generator by correcting the local clock generator based on the time difference. The method may include acquiring MR echo signals by scanning at least a part of a subject in response to the clock signal generated by the corrected local clock generator. The method may further include digitizing the MR echo signal at the coil side assembly.
