Abstract
A local coil for detecting nuclear magnetic resonance signals from an examination subject, for spectroscopic analysis or image construction, has a coaxial conductor member shaped to form a first turn of the coil, with the inner conductor of the coaxial member exiting the jacket upon the completion of the first turn, and the unshielded inner conductor forming a second turn of the coil in the same winding direction as the first turn, and being connected to the jacket upon completion of the second turn. The coil is thus symmetrical with respect to ground, independent of frequency, and is balanced so that it can be directly connected to an asymmetrical coaxial cable.
