Abstract: The invention relates to a magnetic resonance coil array (30) of a magnetic resonance system having a distributed cable routing realized by a self-compensated radiofrequency choke (10). The magnetic resonance coil array (30) comprises multiple magnetic resonance receive coils (32), an input-output unit (34), and multiple coaxial cables (14) interconnecting the magnetic resonance receive coils (32) with the input-output unit (34). The coaxial cable (14) comprises the self-compensated radiofrequency choke (10). The self-compensated radiofrequency choke (10) 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 (10) comprises a choke housing (12) having a toroidal form and the coaxial cable (14), wherein the coaxial cable (14) is wound around the choke housing (12) 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 (10) to be resonant to the B1-excitation field.
