Abstract
Systems and methods for reducing an amount of space occupied by a radio frequency coil assembly in a magnetic resonance imaging system are provided. In one embodiment, a radio frequency coil assembly for a magnetic resonance imaging system includes a radio frequency coil disposed cylindrically around a patient space and a radio frequency shield disposed cylindrically around the patient space and electrically coupled to the axial ends of the radio frequency coil. The radio frequency shield may be configured to extend behind the radio frequency coil, and the axial length of the radio frequency shield may be at least two times the axial length of the radio frequency coil.

A radio frequency coil assembly for a magnetic resonance imaging system comprising:
- a radio frequency coil disposed cylindrically around a patient space;
- and
- a radio frequency shield disposed cylindrically around the patient space and electrically coupled to the axial ends of the radio frequency coil, wherein the radio frequency shield is configured to extend behind the radio frequency coil away from the patient space, wherein the axial length of the radio frequency shield is at least two times the axial length of the radio frequency coil.
A magnetic resonance imaging system comprising:
- a gradient coil assembly disposed cylindrically around a patient space;
- and
- a radio frequency coil assembly disposed cylindrically around the patient space and entirely within the cylinder formed by the gradient coil assembly, wherein the radio frequency coil assembly has a thickness of less than two centimeters.
A magnetic resonance imaging system comprising:
- a cylindrical radio frequency coil assembly having a thickness of two centimeters or less.
