    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： 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.

    摘要： A cooling unit operating in a magnetic field is provided. The cooling unit includes an encasement body having a non-electrically conductive composition and defining a first and second opposing planar surface. The cooling unit also includes a metal conduit disposed in the encasement body substantially parallel to the first surface. Additionally, the cooling unit also includes a series of metal fins disposed in the encasement body and extending from the conduit. In some configurations the fins can be substantially parallel to the first surface. Further, in some configurations, non-electrically conductive inserts having a thermal conductivity greater than a thermal conductivity of the encasement body can be disposed in a portion of the encasement body between one of the first and second surfaces and one or more of the metals fins.

    摘要： An antenna unit for a PET/MRI scanner is disclosed, including a supporting tube in which at least one antenna for MR signals is arranged. In at least one embodiment, the supporting tube has at least one permeable section and one impermeable section, the permeable section of which has a greater permeability to PET quanta than the impermeable section. The antenna unit further includes a screen for radio-frequency signals which is arranged outside of the supporting tube and surrounds the latter. In at least one embodiment, an intermediate layer is arranged between the supporting tube and the screen and, in the region of the permeable section of the supporting tube, is composed of, at least in part, a material which has a permeability to PET quanta comparable to the permeable section.
