Abstract
A parallel plate waveguide forms a volume coil used for magnetic resonance imaging and spectroscopy. The waveguide includes a first conductor arranged on a first side of the waveguide and a second conductor arranged on a second side of the waveguide. Excitation of the first conductor and the second conductor creates a transverse electromagnetic field between the first conductor and the second conductor which causes a target within the volume coil to emit radio frequency signals used for producing an image of the target.
Claims18
A device, comprising:
- a waveguide forming a volume coil for containing a target to be imaged, wherein the waveguide includes:
- a first conducting plate arranged on a first side of the waveguide;
- and
- a second conducting plate arranged on a second side of the waveguide, such that excitation of the first conducting plate and the second conducting plate creates a transverse electromagnetic field between the first conducting plate and the second conducting plate which causes the target contained within the volume coil, between the first conducting plate and the second conducting plate, to emit radio frequency signals used for producing an image of the target;
- wherein the waveguide is configured to act as a transmission line resonator to facilitate signal reception, and wherein a length of the waveguide transmission is equal to an odd number of wavelengths at a resonant frequency for signal reception.

- a first conducting plate arranged on a first side of the first waveguide;
- a second conducting plate arranged on a second side of the first waveguide such that excitation of the first conducting plate and the second conducting plate creates a first transverse electromagnetic field between the first conducting plate and the second conducting plate;
- a third conducting plate arranged on a first side of the second waveguide;
- and
- a fourth conducting plate arranged on a second side of the second waveguide, such that excitation of the third conducting plate and the fourth conducting plate creates a second transverse electromagnetic field between the third conducting plate and the fourth conducting plate,
- wherein the first and second transverse electromagnetic fields cause the target contained within the volume coil, between the first conducting plate and the second conducting plate, to emit radio frequency signals used for producing an image of the target.
