摘要： An RF coil assembly is presented that incorporates balun networks to eliminate standing waves from cables used to apply a voltage to multiple drive ports of the coil. Each drive port is driven by an applied voltage that is shifted 90 degrees in the tangential direction. Further, all drive ports are located on one end-ring of the coil, e.g. the superior end-ring. The inequality of the efficiency of the drive ports is reduced such that a substantially circular polarization in the volume of the coil is maintained. The present invention reduces asymmetrical loading by a patient as a result of patient asymmetry and patient contact with the opposite end-ring of the coil that normally negatively affects circular polarization and conventional coil configurations.

摘要： An assembly of RF coils for bilateral imaging of a first and a second breast of the same person is disclosed. The assembly includes a first pair of coils having a first coil juxtaposed and underlapping a second coil, thereby defining juxtaposed edges of the first and second coils, and a second pair of coils having a third coil juxtaposed and underlapping a fourth coil, thereby defining juxtaposed edges of the third and fourth coils. The first coil has a first opening for receiving the first breast, the second coil has a second opening for receiving the second breast, the third coil substantially opposes the first coil, defining therebetween a first region for receiving the first breast, and the fourth coil substantially opposes the second coil, defining therebetween a second region for receiving the second breast.
