System and method for magnetic resonance imaging of one or more subjects

An MRI system for imaging one or more subjects is provided. The MRI system includes a magnet assembly and an MRI controller. The magnet assembly includes an RF coil for transmitting a first set of RFpulses into the one or more subjects at an initial Larmor frequency. The MRI controller is configured to electronically communicate with the RF coil and to adjust a resonant frequency of the RF coil such that the RF coil transmits a second set of RF pulses into the one or more subjects at one or more subsequent Larmor frequencies that are different from the initial Larmor frequency. 提供了种用于对个或多个受检者进行成像的MRI系统。MRI系统包括磁体组件和MRI控制器。磁体组件包括用于将第组RF脉冲以初始拉莫尔频率发送到所述个或多个受检者中的RF线圈。MRI控制器被配置成与RF线圈电子地连通并且调整RF线圈的共振频率，使得RF线圈将第二组RF脉冲以不同于初始拉莫尔频率的个或多个后续拉莫尔频率发送到个或多个受检者中。
