摘要:
A supply line apparatus for an electrical connection of a gradient coil unit in a magnetic resonance device includes a first supply line unit and a second supply line unit. The second supply unit is disposed at least partially coaxially to the first supply line unit. The first supply line unit and/or the second supply line unit has at least one conducting supply line element. The supply line apparatus includes an oscillation decoupling unit that has at least one oscillation-suppressing supply line element.
摘要:
Base compositions for addition-crosslinking silicone compositions are continuously produced by, in a first stage, homogeneously mixing and kneading organopolysiloxanes and flowable prehydrophobized oxidic reinforcing fillers in a continuous kneading machine with kneading chambers arranged alongside one another. In a second, downstream, stage of the process, the compositions produced in the first stage are subjected to aftertreatment in a mixing apparatus in which the compositions have been subjected to a mixing procedure with introduction of shear force.

The present embodiments relate to a magnetic resonance tomography system having a basic-field field generation device for generating a basic magnetic field. The magnetic resonance tomography system also includes a gradient-field field generation device for generating a gradient field, where the basic-field field generation device and the gradient-field field generation device are arranged in an evacuatable low-pressure housing.
摘要:
In a method to ensure the removability and/or the mobility of at least one element cast in a casting compound for a module of a medical apparatus, wherein the element is coated with a meltable substance before the casting, the meltable substance is melted by heating after the casting in order to remove and/or to produce the mobility of the element.
摘要:
A gradient coil of a magnetic resonance apparatus has a first conductor structure and a second conductor structure connected with one another so that windings of the gradient coil are formed. The first conductor structure is formed exclusively of planar, electrically conductive elements that are insulated from one another. The second conductor structure is formed exclusively of conductive wires insulated from one another.
摘要:
An arrangement for the adjustment of the homogeneity of a basic magnetic field in a magnetic resonance apparatus includes gradient coil support fashioned to support a gradient coil system. The gradient coil support has at least one channel that is fashioned to accommodate an associated shim tray. The shim tray is designed to accommodate ferromagnetic shim elements at predetermined positions in order to adjust the homogeneity of the basic magnetic field of the magnetic resonance apparatus. The shim tray has a first locking element coupled with it. The channel has a second locking element, and the first and second locking element are shaped such that both are positively connected with one another by a force produced by the basic magnetic field of the magnetic resonance apparatus upon activation thereof.
摘要:
Sealed components for an MRI scanner, in particular carrying RF coils and gradient coils have actuators for active noise control that are a part of an actuator module having holding segments fastened rigidly to the opposite ends of the actuator. The holding segments are fastened by screws onto two actuator receiving elements that are embedded at a spacing from one another in the sealing compound, and so that each fastening segment protrudes into a recess in the compound.
摘要:
In a method for the production of an insulated plate for a gradient coil, bodies that serve as spacers for the creation of flow paths for a casting resin are produced on a base by a plate having apertures therein being used to spread the bodies on the base or to mold the bodies on the base from a moldable material.
