RF coil structure for intra-cavity use in magnetic resonance imaging
First Claim
1. An RF coil structure for intra-cavity use in MRI comprising:
- a pair of conductors joined by a support, the conductors forming a first elongate coil adapted for intra-cavity use, the coil being flexible transverse to the plane of the coil, wherein the spacing between the conductors varies along the length of the coil such that the conductors are close together at positions separated along the length of the coil, whereby flexing of the coil in the plane of the support is also possible.

Abstract
An RF coil structure for intra-cavity use includes a pair of conductors (7, 8) separated by a support such as a web (9) which come together at positions separated along the length of the coil structure such as (A, B). Previous coils have included two parallel conductors. If the conductors (7) and (8) were parallel, while the structure could be flexed transverse to the plane of the web (9) about the arrow (10), it could not be flexed in the plane of the web (9) about arrows (12, 13). Because the conductors come together at points (A) and (B), it can be so flexed. A second coil may be provided including conductors (4, 5) and flexing about the same points as for the first coil is still possible because the points of closest approach for one pair come between those for the other pair.
