1. A coil assembly, comprising:
a supporting assembly, a shape of the supporting assembly being a hollow cylinder; and
a volume transmit coil supported on the supporting assembly, the volume transmit coil having at least eight coil loops and at least eight transmission ports, each of the at least eight coil loops sharing a common side with at least one adjacent coil loop, and the common side having at least one decoupling capacitor connected therein, wherein
at least one of the at least eight transmission ports is operably connected to a single coil loop of the at least eight coil loops;
each of the at least eight transmission ports is configured to transmit a drive signal to one of the at least eight coil loops for generating a magnetic field; and
an amplitude and a phase of the drive signal transmitted by the each of the at least eight transmission ports are set independently.
