  • Publication number: 20250172645
    Abstract: The present disclosure provides a magnetic resonance imaging (MRI) radio frequency (RF) coil assembly. The MRI RF coil assembly may include one or more coils and one or more control circuits. Each of the one or more coils may include a first end and a second end. Each of the one or more control circuits may electrically connect the first end and the second end of one of the one or more coil. Each of the one or more control circuits may be configured to adjust an operation of the coil that is electrically connected with the control circuit based on an input control signal. The one or more control circuits may be located at different regions.

  • Publication number: 20250138116
    Abstract: Transmission cable assemblies and methods for suppressing common-mode currents on a transmission cable are provided. The transmission cable assembly may include a transmission cable and at least one trap fitted on the transmission cable. Each trap may include a first coil and a second coil in opposite helical directions and assembled to allow the transmission cable to insert through. The first coil and the second coil form a resonant circuit for reducing common-mode currents on the transmission cable. When there are multiple traps fitted on the transmission cable, they are spaced apart along the longitudinal axis of the transmission cable and an insulating component is placed between every two adjacent traps. The designs can make the trap filters smaller and lighter in weight while effectively reducing the impact on the local radiofrequency (B1) field.

  • Publication number: 20240264256
    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.
