    摘要： Magnetic resonance device with an assembly having a recess, in which a gradient coil unit is attached with at least one attachment means, the attachment means having two members, between which an elastic element is disposed, only one of the members in each instance being in contact with either the gradient coil unit or the assembly, with the attachment means acting as an attachment means having no elastic element in a first attachment state, in which at least a minimum force presses the two members together, in that the two members have stop surfaces, which are in contact with each other due to the minimum force acting on the members compressed elastic element and with the attachment means acting as a spring unit in a second fixing state, in that the elastic element pushes the members apart in the event of forces smaller than the minimum force and causes the attachment means to be fixed in relation to the gradient coil unit and the assembly. 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.

    摘要： A magnetic resonance apparatus has a basic field magnet with an interior bore having a bulge therein. A mass augmentation device is disposed in the bulge, and is composed of a number of assembled individual segments. The mass augmentation device reduces the propagation of mechanical oscillations that are produced during operation of the magnetic resonance apparatus, and which otherwise would produce unwanted noise.

    摘要： At least one embodiment is directed to a combination of an MR tomograph and a positron emission tomograph having avalanche photodiodes as reception elements. In at least one embodiment, the intention is to ensure that the avalanche photodiodes are kept at a constant temperature despite the exposure to heat from the MR components. It is proposed, in at least one embodiment, that cooling by Peltier elements 5 should be provided.

    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.
