摘要：A radio frequency (RF) switch device has at least two RF switch units, each RF

switch unit having an output terminal and at least two input terminals. The RF switch unitsselect one channel of RF signals from several channels of the RF signals that are suppliedas inputs to their input terminals for emission as an output from their output terminals. Amagnetic resonance imaging system and an RF signal transmission method employ suchan RF switch device. The use of such an RF switch device reduces the number of channelsof the RF signals that need to be further transmitted, which in turn reduces the numberof the corresponding long RF cable channels and the number of channels of thesubsequent devices, thereby preventing waste and reducing the cost of the system.Moreover, if the subsequent devices include a receiver coil channel selector, then thecomplexity of the receiver coil channel selector will also be reduced as the number of RFsignal channels is decreased.
