Abstract
The present invention aims to provide an RF coil assembly capable of eliminating the need for connecting and disconnecting an electric path at decoupling portions and is an RF coil assembly including: a plurality of coil loops that are adjacent to each other in sequence and construct a phased array; and a plurality of decoupling device that cancel electromagnetic coupling between adjacent coil loops, respectively, wherein at least two of the plurality of coil loops are two coil loops that are adjacent to each other across a boundary where they can be decoupled from each other, and wherein at least one of the plurality of decoupling device is two coils that are connected in series to the two coil loops, respectively, and are opposed to each other across the boundary and form a pair of coils for decoupling.

A radio frequency (RF) coil assembly comprising:
- a phased array comprising a plurality of RF coils, said plurality of RF coils comprising:
- a plurality of coil loops in sequence defining a circumference;
- and
- a plurality of decoupling devices configured to cancel an electromagnetic coupling between adjacent coil loops of said plurality of coil loops, said plurality of decoupling devices positioned about the circumference,
- wherein at least two coil loops of said plurality of coil loops are adjacent to each other across a boundary such that said at least two coil loops can be decoupled, and
- wherein at least one decoupling device of said plurality of decoupling devices comprises two coils connected in series to said at least two coil loops, and are opposed to each other across the boundary and form a pair of coils for decoupling;
- and
- an elliptical shaped supporting body having an exterior surface coupled to said phased array, said elliptical shaped supporting body comprising:
- a semi-elliptical shaped anterior supporting body portion;
- and
- a semi-elliptical shaped posterior supporting body portion that is removably coupled to said anterior supporting body portion, said anterior and posterior supporting body portions configured to support said plurality of RF coils.
