Coaxial Cable Magnetic Resonance Image (MRI) Coil

摘要

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.

主权项

1. A magnetic resonance imaging (MRI) radio frequency (RF) coil, comprising:
a first terminal; a second terminal; and a coaxial cable that connects the first terminal and the second terminal, where an inner conductor of the coaxial cable is continuous between the first terminal and the second terminal, and where an outer conductor of the coaxial cable is not continuous between the first terminal and the second terminal.
