用于超高场MRI的路由器和线圈阵列
摘要：
路由器（60），其用于与磁共振系统（10）一起使用，将由多通道射频（RF）放大器生成的独有的激励信号通过发送线路（Tx）有选择地路由到多个连接板（66）中的任一个，每个连接板（66）接收具有多个线圈元件（20）的至少一个RF线圈组件。每个连接板（66）包括收发器端口（68），所述收发器端口（68）用于将所述线圈元件（20）的至少一个导体（22、24）连接到相应收发器通道（T/R）。所述路由器（60）将由所述导体（22、24）从所述收发器通道（T/R）接收的磁共振信号有选择地路由到多通道RF接收器（41）。线圈元件可以承载正弦模式电流或均匀电流。
摘要（英）：

A router (60), for use with magnetic resonance systems (10), selectively routes unique excitation signals, generated by a multi-channel radio-frequency (RF) amplifier,over transmission lines (Tx) to any one of a plurality of connection panels (66) which each accepts at least one RF coil assembly having multiple coil elements (20). Each connection panel (66) includes transceiver ports (68) for connecting at least one conductor (22,24) of the coil elements(20) to a corresponding transceiver channel (T/R). The router (60) selectively routes magnetic resonance signals received by the conductors (22,24) from the transceiver channels (T/R) to a multi-channel RF receiver (41).
