IMAGING REGION-SPECIFIC RADIO FREQUENCY COILS FOR MRI

摘要

A radio frequency coil includes a non-cylindrical conformal surface (62, 76) that substantially conforms with a magnetic resonance subject. A plurality of conductor loops (60, 71, 72, 73, 74) are disposed in or on the non-cylindrical conformal surface. The plurality of conductor loops are configured to produce a substantially uniform Bi field in the magnetic resonance subject responsive to energizing at a Bi frequency. Optionally, a plurality of load-compensating conductor loops (90) are disposed in or on a compensatory non-cylindrical conformal surface (62) that substantially conforms with a magnetic resonance subject. The plurality of load-compensating conductor loops are configured to produce a non-uniform Bi field that compensates for a loading Bi non-uniformity caused by the magnetic resonance subject.
