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： Magnetic resonance device (1) with an assembly (3) having a recess, in which a gradient coil unit (9) is attached with at least one attachment means (15, . . . 15D), the attachment means (15 ... 15D) having two members (21,23), between which an elastic element (25) is disposed, only one of the members (21,23) in each instance being in contact with either the gradient coil unit (9) or the assembly (3), with the attachment means (15, . . . 15D) acting as an attachment means (15, . . . 15D) having no elastic element (25) in a first attachment state, in which at least a minimum force (FMIN) presses the two members (21, 23) together, in that the two members (21, 23) have stop surfaces (31), which are in contact with each other due to the minimum force acting on the members (21, 23) [lacuna] compressed elastic element (25) and with the attachment means (15, . . . 15D) acting as a spring unit in a second fixing state, in that the elastic element (25) pushes the members (21, 23) apart in the event of forces smaller than the minimum force (FMIN) and causes the attachment means (15, . . . 15D) to be fixed in relation to the gradient coil unit (9) and the assembly (3). 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： The present embodiments provide a gradient coil assembly. The gradient coil assembly includes an aluminum wire body, and a copper wire end connected by cold pressure welding to two ends of the aluminum wire body. Using the gradient coil according to a particular embodiment, it is possible to reduce gradient coil weight as well as reduce the thickness of an outer vacuum chamber used for a magnet, thereby reducing the cost of the magnet and gradient coil, and making it less difficult to install and maintain the magnet and gradient coil. There is no problem of oxidation associated with the cold pressure welding of the aluminum wire body to the copper wire ends, so quality defects arising from such oxidation are avoided.
