    • An RF shielded room (14) which houses a magnetic resonance scanner (12) also houses a patient monitor (20) which includes a plurality of sensors (18) which collect physiological data about a patient undergoing a magnetic resonance examination. The monitor includes a transmitter (46) which transmits the physiological data on at least two frequency channels of a broadband frequency spectrum. A communication unit (26) located outside the RF shielded room includes first and second receivers (54, 58) which receive the physiological data from the monitor on the first and second frequency channels, respectively. A processor (62) combines physiological data received by the first and second receivers to. A display (32) displays the combined physiological data. A switch (56) switches antenna connections of the receivers (54, 58) responsive to detection of multipath fade.
    • 容纳磁共振扫描仪(12)的RF屏蔽室(14)还容纳患者监护仪(20),其包括多个传感器(18),该传感器收集关于经历磁共振检查的患者的生理数据。 监视器包括在宽带频谱的至少两个频率信道上发送生理数据的发射机(46)。 位于RF屏蔽室外部的通信单元(26)包括分别在第一和第二频道上从监视器接收生理数据的第一和第二接收器(54,58)。 处理器(62)将由第一和第二接收器接收的生理数据组合到一起。 显示器(32)显示组合的生理数据。 响应于多径衰落的检测,开关(56)切换接收器(54,58)的天线连接。
