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.

Abstract: A local coil apparatus for performing a magnetic resonance (MR) scanning on a local part of a subject is provided. The local coil apparatus may include at least one receiving system for receiving the local part. The at least one receiving system may each include an activation member, a receiving member assembly, and a driving mechanism. The receiving member assembly may include one or more receiving members. Each of the one or more receiving members may include a first coil assembly configured to receive MR signals during the MR scanning. The driving mechanism may be physically connected to the one or more receiving members. When the local part is placed on the activation member, the activation member may cause the driving mechanism to drive the receiving member assembly to change from a first configuration to a second configuration to reduce a distance between at least a portion of the first coil assembly and a portion of the local part so that the first coil assembly conforms to the local part.
