摘要： A method for producing at least one saddle coil for a gradient coil layer for a magnetic resonance tomography system is provided. At least one half cylinder-shaped, premolded saddle coil is arranged between an inner shell and an outer shell of a casting apparatus. The shells of the casting apparatus are closed, and the space between the shells is filled with a casting compound.

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.
摘要翻译：磁共振装置具有具有凹部的组件，其中梯度线圈单元附接有至少一个附接装置，所述附接装置具有两个构件，在所述两个构件之间设置有弹性元件，每个构件中只有一个构件处于与梯度线圈单元或组件接触，附接装置用作在第一附接状态下没有弹性元件的附接装置，其中至少最小的力将两个构件压在一起，因为两个构件已经停止由于作用在构件压缩弹性元件上的最小力和作为第二固定状态的弹簧单元的附接装置彼此接触的表面，因为弹性元件在构件压缩弹性元件力小于最小力并且使附接装置相对于梯度线圈单元和组件固定。这具有的优点是即使在热波动的情况下也不会特别地使连接装置松动。

摘要： A magnetic resonance apparatus has a cylindrical gradient coil with an x-gradient coil and a y-gradient coil that are asymmetrical relative to the z-direction of a coordinate system, the z-direction extending along a longitudinal direction of a patient receptacle. Shim coils are provided that generate magnetic fields to homogenize the basic magnetic field, produced by a cylindrical basic field magnet, in an examination volume in the patient receptacle. At least some of the shim coils are asymmetrical relative to the z-direction to minimize coupling induction between the asymmetrical x-gradient coil and y-gradient coil and the asymmetrical shim coils.
