1. An open-structured RF transmitting and receiving coil system, the system comprising:
a magnetic field generation part comprising a first electromagnet set comprising one or more electromagnets facing a region of interest (ROI) in a three-dimensional space and a second electromagnet set comprising one or more electromagnets disposed symmetrically with the first electromagnet set;
coupling parts coupled to the electromagnet sets, respectively;
a detection part disposed below the region of interest;
a cancellation part connected to the detection part; and
a power source part configured to independently apply current to each of the electromagnets,
wherein the cancellation part comprises a second Rx coil and a second Tx coil and has a second through hole in the center thereof, the cancellation part further comprising a calibration coil section at one side of the second through hole.
