    摘要： A dielectric element for positioning on an examination subject for locally influencing the B1 field distribution during magnetic resonance data acquisition contains a relaxation agent bound to mutually separated particles. The relaxation agent incorporates a paramagnetic substance. In a corresponding method for acquiring magnetic resonance data from an examination subject, such a dielectric element is positioned on the examination subject for locally influencing the B1 field distribution, by homogenizing the B1 field of a magnetic resonance apparatus.

    摘要： A local coil unit for a magnetic resonance apparatus, which radiates a radio-frequency field into an examination subject, has a housing and at least a part of the housing is formed of an insulating dielectric material that passively compensates for an inhomogeneity in the high-frequency field in the subject. The material has a relative dielectric value εr of greater than 50, preferably greater than 100, and a dielectric loss factor tan δ of less than 2.5×10−2, preferably less than 1×10−3. In the dielectric material displacement currents are generated which create an additional magnetic field that compensates for the minima in the B1 field as a result of the eddy currents arising in the patient due to the radio-frequency radiation.

    摘要： For generating of magnetic resonance exposures of an examination subject, a dielectric element with high dielectric constant is positioned on the examination subject to locally influence the B1 field distribution, the dielectric element being formed primarily of material whose magnetic resonance line(s) is/are shifted by at least a specific degree relative to the magnetic resonance line of water protons for a given magnetic field. In a measurement for generation of a magnetic resonance exposure a measurement sequence is used, such in the acquisition of the raw image data the dielectric material of the dielectric element supplies no signal contributions for the image generation and/or the signals caused by the dielectric material of the dielectric element can be separated from the signals caused by the examination subject.

    摘要： In a method for manufacturing a gradient coil system for a magnetic resonance apparatus, the conductor arrangement of the gradient coil system is produced by successively applying respective layers of metal powder sinter material on a workpiece platform, and successively sintering the respective layers by the application of radiation, such as laser radiation, to the individual layers, and the conductor arrangement is assembled with other components to produce the gradient coil system. A gradient coil system manufactured in accordance with this method includes a number of assembled components, including an electrical conductor arrangement, with the electrical conductor arrangement having conductors formed by radiation-sintered metal powder material.

This has the advantage that there is no loosening of the attachment means in particular even in the event of thermal fluctuations.

    摘要： In a shim board system with at least one shim board formed by an insulating substrate and at least one conductor trace on the substrate for generation of a shim magnetic field, in particular for homogenization of the basic magnetic field of a magnetic resonance apparatus, the insulating substrate is fashioned as a mesa in at least one segment similar to the conductor trace and following the curve of the conductor trace. Upon sealing, this allows a good saturation of the shim board system with sealing compound.
