A radio frequency (RF) coil assembly for magnetic resonance imaging includes a transmit only (Tx only) RF coil to apply an RF signal to an object, and a receive only (Rx only) RF coil to receive a magnetic resonance signal from a region of interest of the object excited by the applied RF signal. The Tx only RF coil and the Rx only RF coil are disposed such that a first center of the Tx only RF coil and a second center of the Rx only RF coil are spaced apart from each other by a distance identical to a distance between a first peak point of a first magnetic field generated by the Tx only RF coil and a second peak point of a second magnetic field generated by the Rx only RF coil.
