Abstract
The invention relates to a magnetic resonance coil array () of a magnetic resonance system having a distributed cable routing realized by a self-compensated radiofrequency choke (). The magnetic resonance coil array () comprises multiple magnetic resonance receive coils (), an input-output unit (), and multiple coaxial cables () interconnecting the magnetic resonance receive coils () with the input-output unit (). The coaxial cable () comprises the self-compensated radiofrequency choke (). The self-compensated radiofrequency choke () allows to replace conventional bulky resonant radiofrequency traps used in conventional magnetic resonance coil arrays and allows implementing the distributed cable routing. The self-compensated radiofrequency choke () comprises a choke housing () having a toroidal form and the coaxial cable (), wherein the coaxial cable () is wound around the choke housing () in a self-compensated winding pattern. The self-compensated winding pattern provides compensation for a B1-excitation field of a magnetic resonance system and eliminates the need for the self-compensated radiofrequency choke () to be resonant to the B1-excitation field.
