    • A system and method for magnetic resonance imaging (MRI) and static field (B0) shimming. A coil system includes a conductive loop configured to be arranged proximate to a region of interest (ROI). The coil system also includes an alternating current (AC) circuit electrically connecting the conductive loop to an AC electrical connection configured to be coupled to an MRI system to communicate medical imaging signals received by the conductive loop from the ROI during a medical imaging procedure to the MRI system. The coil system further includes a direct current (DC) circuit electrically connecting the conductive loop to a DC electrical connection configured to be coupled to a DC power source and a plurality of circuit components configured to block DC signals from reaching the AC electrical connection in order to produce a spatially varying static magnetic field for shimming inhomogenieties of the static field.
    • 用于磁共振成像(MRI)和静态场(B0)匀场的系统和方法。 线圈系统包括被布置成靠近感兴趣区域(ROI)布置的导电回路。 线圈系统还包括将导电回路电连接到AC电连接的交流电(AC)电路,AC电连接被配置为耦合到MRI系统,以将在医疗成像过程期间由导电回路接收的医学成像信号从ROI传送到ROI MRI系统。 线圈系统还包括直流(DC)电路,其将导电回路电连接到被配置为耦合到DC电源的DC电连接,以及多个电路部件,其被配置为阻止DC信号按顺序到达AC电连接 以产生空间变化的静磁场,用于匀场静电场的不均匀分布。
