Abstract
Radio frequency (RF) coil configurations and methods are disclosed. Non-magnetic elements may be used in combination with an RF coil. The non-magnetic elements may be metal. The non-magnetic metal elements may be designed and configured to facilitate tuning of an RF coil, and to modify a magnetic field produced by an RF coil. The non-magnetic metal elements may also be used in connection with a RF receiver coil to control the region from which the receiver coil detects signals. The configurations and methods described may be used in various RF applications, including magnetic resonance imaging (MRI).
Claims35
An apparatus, comprising:
- a radio frequency (RF) coil;
- and
- a non-magnetic metal element electromagnetically coupable to the RF coil to do at least one of form a resonant system with the RF coil, focus a magnetic field produced by the RF coil, and increase a sensitivity of detection of the RF coil.
