OG exemplary drawing
 
1. A local coil, comprising:
a flat carrier body;
at least one ventilation opening; and
an antenna array to receive RF signals in a frequency and power range of a magnetic resonance device, the antenna array including a termination to establish an electrical connection to the magnetic resonance device, wherein the antenna array is embedded in the local coil, a first outer skin and a second outer skin enclosing the flat carrier body on two main surfaces facing away from one another,
wherein the first outer skin and the second outer skin are disjunctively and integrally bonded to the flat carrier body,
wherein the flat carrier body includes a reversibly deformable material and is moldable to a shape of the patient, and
wherein the local coil includes at least one filler, the at least one filler being unattachedly embedded in the flat carrier body and designed to reduce transmission of at least one of a shear force and a bending force in the local coil upon the local coil being molded to the shape of a patient.
 
12. A magnetic resonance system, comprising:
a magnetic resonance device;
the local coil of claim 1; and
an electrical connecting cable, electrically connected to the termination of the antenna array and the magnetic resonance device and designed to establish a signal connection between the magnetic resonance device and the antenna array.
