Abstract: A rotating body coil assembly for use with an open MR magnet for imaging at least a portion of a subject comprises a resonant structure configured to rotate about the subject and to permit access to the subject during imaging. The body coil assembly comprises first and second end ring assemblies positioned on opposing sides of the imaging space. The first and second end ring assemblies are each configured to energize the body coil assembly. A plurality of element assemblies are disposed between and connecting the first and second end ring assemblies for providing structural support and electrical isolation of the body coil assembly. A base assembly is coupled to the first and second end ring assemblies and at least one of the element assemblies. The base assembly is adapted to rotate the first and second end ring assemblies in cooperation with the plurality of element assemblies about the portion of the subject while the portion of the subject is inside the imaging space for permitting access to the subject during imaging.

Abstract translation: 用于与开放的MR磁体一起使用以用于对受试者的至少一部分进行成像的旋转体线圈组件包括构造成围绕被摄体旋转并且允许在成像期间进入对象的共振结构。 身体线圈组件包括位于成像空间的相对侧上的第一和第二端环组件。 第一和第二端环组件各自被构造成对体线圈组件通电。 多个元件组件设置在第一和第二端环组件之间并且连接第一和第二端环组件，以提供主体线圈组件的结构支撑和电隔离。 基座组件联接到第一和第二端环组件以及元件组件中的至少一个。 所述基座组件适于使所述第一和第二端环组件与所述多个元件组件一起围绕所述对象的所述部分旋转，而所述对象的所述部分在所述成像空间内，以允许在成像期间访问所述对象。
