A magnetic resonance device comprising a gradient coil assembly having gradient coils is described. The gradient coils are supported by at least one cylindrical coil carrier for generating gradient fields. As part of the gradient coil assembly, at least one vibration sensor is provided for measuring vibrations of the gradient coil assembly at least in a radial direction of oscillation.

Magnetic resonance device, magnetic resonance system and associated operating method

A magnetic resonance apparatus includes a magnet unit that contains a high-frequency antenna unit, and a housing casing unit enclosing the magnet unit. The housing casing unit includes a side casing unit, a front casing unit, and a rear casing unit. The side casing unit, the front casing unit, and/or the rear casing unit includes at least one casing part. At least one boundary region of the housing casing unit is disposed between the different casing parts. The housing casing unit includes at least one membrane unit that contains a barrier for the propagation and/or transmission of sound waves and that covers at least one boundary region between two casing parts.

Magnetic resonance apparatus

A magnetic resonance device is proposed. The device has a magnet unit having a cylindrical radio frequency coil unit, a cylindrical accommodation area for accommodating a patient, and a housing unit surrounding the magnet unit with at least one housing shell unit. The radio frequency coil unit cylindrically surrounds the accommodation area. The housing shell unit is disposed between the accommodation area and the radio frequency coil unit. The at least one housing shell unit is constituted at least partially by a flexible spring/mass unit.

Cylindrical magnetic resonance device having a circular arc shaped housing shell when mounted that becomes bar-shaped when demounted

A magnetic resonance apparatus is proposed. The magnetic resonance apparatus has a magnet unit and a housing unit surrounding the magnet unit. The housing unit has a first housing shell unit and a second housing shell unit. The second housing shell unit is arranged between the magnet unit and the first housing shell unit.

Double shell noise reducing magnetic resonance apparatus

A magnetic resonance apparatus is proposed. The magnetic resonance apparatus has a magnet unit, magnet housing and a housing unit surrounding the magnet unit. The housing unit includes at least one support structure unit and a cladding unit. The cladding unit has at least one first layer, which includes a sound absorption element, and at least one second layer, which includes a heavy mass layer.

Magnetic resonance apparatus with sound absorption cladding and irregular grid

A magnetic resonance apparatus is proposed. The magnetic resonance apparatus has a magnet unit and a housing unit. The housing unit has a housing shell unit. The housing shell unit surrounds the magnet unit. The housing shell unit at least partly has a flexible material. Effective noise protection for operation of the magnetic resonance apparatus is provided.
