摘要： A transmit coil arrangement for a magnetic resonance device includes a plurality of individually actuatable conductor loops following one after another in a peripheral direction and a longitudinal direction on a cylinder surface. At least two groups, at a distance from one another in the peripheral direction, of at least two conductor loops following one after the other in the longitudinal direction are provided in the peripheral direction. To decouple the at least two groups, each of the at least two groups is bounded at least in the peripheral direction by at least one screen surface extending essentially in a radial direction and the longitudinal direction.

摘要： A method determines an optimal structure of a high-frequency shield of a high-frequency antenna of a magnetic resonance arrangement. The high-frequency shield shields the high-frequency antenna from a gradient-coil arrangement. A three-dimensional initial structure of the high-frequency shield is defined in accordance with structural parameters and jointly with the high-frequency antenna, the gradient-coil arrangement, or both the high-frequency antenna and the gradient-coil arrangement. The structural parameters are optimized via an optimization method with respect to at least one optimization criterion.

摘要： A magnetic resonance antenna arrangement includes at least one first antenna group including individually-controllable first antenna conductor loops and a second antenna group adjacent to the first antenna group. The second antenna group includes individually-controllable, longitudinal second antenna elements. The first antenna conductor loops essentially extend in a first extending surface and are disposed in the first extending surface in a first direction in a row behind one another. The longitudinal second antenna elements extend with the longitudinal axes transverse to the first direction disposed in parallel next to one another in a second extending surface that runs essentially in parallel to the first extending surface. Each of the second antenna elements are coupled at first and second end areas to a conductive element to form a second conductor loop with the conductive element. The second antenna elements are disposed to overlap an adjacent first antenna loop in each case.
