First Claim
Patent Images
1. A circuit arrangement comprising:
- at least a first input and a second input, said first and second inputs being adapted for connection to respective MR local coils;
at least a first output and a second output, said first and second outputs being adapted for connection to respective evaluation units;
a first signal line between said first input and said first output and a second line between said second input and said second output;
at least one first sheath wave barrier connected in said first signal line and at least one second sheath wave barrier connected in said second signal line, each of said at least one first sheath wave barrier and said at least one second sheath wave barrier producing a magnetic field, and said at least one first sheath wave barrier and said at least one second sheath wave barrier being configured relative to each other so that the respective magnetic fields produced thereby substantially cancel each other.
