The invention relates to an arrangement for generating RF fields in the examination
volume (100) of an MR apparatus. A plurality of resonator segments are arranged
around the examination volume (100) within the gradient tube (103),
said resonator segments being connected together so as to form a body coil. Each
resonator segment is provided with a conductor element (104) which is constructed
as a planar strip and extends parallel to the longitudinal axis of the main field
magnet. The resonator segments are electromagnetically decoupled from one another
by means of intermediate capacitances, so that a separate transmission channel
(1 to 8) can be associated with each resonator segment, the RF feeding
into the relevant resonator segment taking place via said channel. Because the
phase and the amplitude of the RF feeding can be individually selected for each
resonator segment, the arrangement in accordance with the invention enables substantially
complete control of the RF field distribution in the examination volume (RF shimming).
