    摘要: A gradient coil of a magnetic resonance apparatus has a first conductor structure and a second conductor structure connected with one another so that windings of the gradient coil are formed. The first conductor structure is formed exclusively of planar, electrically conductive elements that are insulated from one another. The second conductor structure is formed exclusively of conductive wires insulated from one another.

    摘要: In a method for adjustment of a shim device of a magnetic resonance apparatus before an image acquisition in a body region that has a volume of interest, a field distribution is measured in a region encompassing the volume of interest produced with a shim device set according to a basic shim data set. A shim data set that is optimized for the volume of interest is determined by a control device starting from the basic shim data set, dependent on the field distribution; and the optimized shim data set is used for adjustment of the shim device. The basic shim data set is selected from a databank of body region-specific input shim data sets.

    摘要: In a method for determination and evaluation of a shim parameter set for controlling a shim device in a magnetic resonance (MR) apparatus, the shim device is set using a first shim parameter set, a first field distribution is measured in a body region encompassing a target volume from which MR data are to be acquired, a second shim parameter set is determined using an algorithm for optimization of the field homogeneity in the target volume on the basis of the first shim parameter set and dependent on the first field distribution, a second field distribution is determined on the basis of the second shim parameter set, and the shim parameter sets are evaluated by indirect or direct comparison of the first field distribution and the second field distribution, in particular in the target volume.
