Abstract
A magnetic resonance receiver system has an antenna arrangement with a number of receiver antenna elements to receive MR response signals. The magnetic resonance system has a combination network arrangement with a number of combination networks in order to combine the MR response signals received by various receiver antenna elements, to form modes, a frequency multiplexer arrangement downstream of the combination network that superimposes at least some of the modes in a common transmission signal, and a transmission line arrangement with a number of transmission lines in order to respectively transfer the transmission signals to an input channel of a first channel switching matrix. This input channel is associated with the transmission line. Downstream of the first channel switching matrix is a frequency demultiplexer arrangement that filters the modes superimposed in a transmission signal out of the transmission signal. Downstream of the frequency demultiplexer arrangement is a second channel switching matrix that connects the modes at specific inputs of an MR signal processing device.
