Abstract
Example magnetic resonance imaging (MRI) radio frequency (RF) coils are described. An MRI RF coil may include a first terminal and a second terminal that are connected by a coaxial cable. Rather than rely exclusively on two terminal passive components (e.g., resistor, inductor, capacitor), example coax MRI RF coils rely on the capacitance that can be created in the coax cable between the inner conductor and the outer conductor. The capacitance of the coil may be controlled by selectively disrupting (e.g., cutting, stripping) the outer conductor, the inner conductor, or the dielectric material disposed between the inner and outer conductor.
