A method for generating a homogeneous high-frequency magnetic field in the interior of a cylindrical body coil a magnetic resonance apparatus, as well as magnetic resonance device for carrying out the method

摘要

A method for generating a of the spin excitation used in a test volume high-frequency magnetic field (12) in the interior of a cylindrical body coil (7) a magnetic resonance device (1), which body coil (7) are arranged distributed around the circumference of a plurality of resonator segments (8) and has a control device (5) to the separate control of the individual, mutually electromagnetically decoupled resonator segments (8) is provided, characterized in that the resonator segments (8) being driven in such a way that the high-frequency magnetic field (12) only in at least one of the examination volume forming the first partial volume (t₁) is produced and, at least one is not excited second partial volume (t₂) magnetic field is substantially freely.
