    • It is an object of the present invention to provide an RF coil and an MRI apparatus capable of ensuring a wide imaging space and excellent in terms of allowing maintenance at the time of installation or failure. In order to do so, an RF coil of the present invention includes a cylindrical outer conductor and a plurality of rung conductors disposed inside the outer conductor along a circumferential direction of the outer conductor. In addition, each of the plurality of rung conductors is electrically connected to the outer conductor through a capacitor so as to form an electrical loop. The outer conductor is divided into a plurality of portions in the circumferential direction and is characterized in that the numbers of rung conductors disposed in at least two divided portions are different. In addition, an MRI apparatus of the present invention includes such an RF coil.
    • 本发明的一个目的是提供一种能够确保宽的成像空间并且在安装或故障时允许维护方面优异的RF线圈和MRI装置。 为了这样做,本发明的RF线圈包括圆柱形外部导体和沿外部导体的圆周方向设置在外部导体内部的多个梯形导体。 此外,多个梯形导体中的每一个通过电容器电连接到外导体,以形成电环路。 外导体在圆周方向上分成多个部分,其特征在于,设置在至少两个分割部分中的梯形导体的数量不同。 此外,本发明的MRI装置包括这样的RF线圈。
