An RF coil system (1) for an MR tomograph comprising a magnet coil system and a gradient coil system is characterized in that the RF coil system is constructed of two partial systems (2, 2') which are arranged essentially laterally reversed with respect to a plane z=0 containing the centre of the measuring volume and have a distance g/2 from the plane z=0, and that each partial system (2, 2') comprises at its axial end facing the plane z=0, a compensation section (3, 3') for homogenizing the RF field drop in the measuring volume caused by the axial gap between the partial systems (2, 2') as compared with an axially continuous and undivided RF coil system (1). The RF coil system (1) in accordance with the invention allows lateral access to the investigation volume in the radial direction and/or offers the possibility to integrate in the RF coil system an adjustment, fixing or support ring surrounding the investigation volume.
