    摘要： Embodiments of the subject invention can utilize a single coil structure for dual-mode operation. In a specific embodiment, a single coil structure can be used as a volume coil in the transmitting phase and as a phase array in the receiving phase. In an embodiment, a transmit coil array in accordance with the subject invention can be utilized for one or more of the following: 1) parallel RF excitation on an MRI scanner equipped with a multiple-channel transmitter; 2) serial RF excitation with the use of a switch system with a single channel transmitter; and 3) generation of a homogeneous B1 field for regular MRI with the use of a power splitter on a standard scanner. In a specific embodiment, the use of a concentric double loop coil with different tunings of inner and outer loops can be implemented. In an embodiment, the coil elements can be decoupled using the CRC mode of a concentric double loop coil. In an embodiment, a surface coil transmit array can provide better compatibility with a receive array. In a specific embodiment, an over-coupled technique can be used to improve the phase control of the transmitting pulse.

    摘要翻译： 本发明的实施例可以利用单线圈结构进行双模操作。 在具体实施例中，单个线圈结构可以用作发射相位中的体积线圈，并且在接收阶段中用作相位阵列。 在一个实施例中，根据本发明的发射线圈阵列可用于以下一个或多个：1）配备有多通道发射器的MRI扫描器上的并行RF激励; 2）使用具有单通道发射器的开关系统进行串行RF激励; 以及3）在标准扫描仪上使用功率分配器产生用于常规MRI的均匀B 1'场。 在具体实施例中，可以实现具有内圈和外圈的不同调谐的同心双环线圈的使用。 在一个实施例中，线圈元件可以使用同心双环线圈的CRC模式去耦合。 在一个实施例中，表面线圈发射阵列可以提供与接收阵列更好的兼容性。 在具体实施例中，可以使用过耦合技术来改善发射脉冲的相位控制。

    摘要： A shading assembly includes two shading supporters, two attaching devices for spacedly and detachably mounting the two shading supporters on the vehicle body respectively, and a shading arrangement including a tubular housing having a receiving cavity detachably attached to one of the shading supporter, and a shading fabric disposed in the receiving cavity. The shading fabric has an inner edge securely received in the tubular housing and outer edge adapted to retractably stretch to detachably attach to another shading supporter to form a shading area for substantially shielding at least a portion of the vehicle body under the shading area.
