    • A magnetic resonance apparatus has an examination region to accommodate a patient to be examined, and a body coil that circumferentially encompasses the examination region and is designed for magnetic resonance examination of the patient. A gradient coil circumferentially encompasses the examination region and the body coil and is designed to detect the position of magnetic resonance measurement values. A basic field magnet is designed to form a basic magnetic field in the examination region for a patient examination to be conducted. The basic field magnet at least partially encompasses the examination region, the body coil and the gradient coil. A shim device is used that is designed to influence the basic magnetic field. Components of the shim device and components of the body coil are associated to exhibit a common distance relative to the longitudinal axis of symmetry of the examination region and thus encompass the examination region.
    • 磁共振装置具有容纳被检查患者的检查区域和周向包围检查区域并被设计用于患者的磁共振检查的体线圈。 梯度线圈周向地包围检查区域和体线圈,并被设计成检测磁共振测量值的位置。 基本场磁体被设计成在检查区域中形成用于进行患者检查的基本磁场。 基本场磁体至少部分地包围检查区域,身体线圈和梯度线圈。 使用设计用于影响基本磁场的垫片装置。 垫片装置的组件和身体线圈的部件相关联,以显示相对于检查区域的纵向对称轴线的公共距离,并且因此包含检查区域。
