PROBLEM TO BE SOLVED: To provide an RF coil system for an open MR apparatus in which, concerning an interest examination volume, while high sensitivity is given in a detection mode, RF magnetic field generated in a transmit mode and a spatial sensitivity profile in the detection mode are limited as much as possible. SOLUTION: This invention relates to the RF coil system for an open MR apparatus. The system consists of a plurality of resonator elements disposed in a region of a patient placed in the examination volume of the MR apparatus. The resonator element is constituted at least partially as a solenoid element having a conductor element forming an open turn disposed in the periphery of the patient. Accordingly, the RF magnetic field generated in the transmit mode and the sensitivity profile in the detection mode are strictly limited to an examination volume as an interest as much as possible. Simultaneously, the RF magnetic field intensity suitable for medical imaging can be generated without exposing the patient to impermissible load.
