Abstract

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.

First claim

The invention claimed is:

1. A magnetic resonance apparatus, comprising:
a magnet unit; and
a housing unit comprising a housing shell unit surrounding the magnet unit, wherein the housing shell unit is embodied as a flexible foil with a foil thickness of approximately 5 mm to 7 mm, and at least one touchscreen operating element integrated into an outward-oriented surface of the housing shell unit that faces away from the magnet unit,
wherein the housing shell unit comprises at least one first form-fit element disposed on at least one internal outer edge area of the housing shell unit,
wherein the housing shell unit further comprises at least one second form-fit element corresponding to the at least one first form-fit element disposed on a corresponding internal interior edge area of the housing shell unit, and
wherein the at least one first form-fit element fits into the corresponding at least one second form-fit element of the housing shell unit so that the edge areas of the housing shell unit containing the at least one first form-fit element and the at least one second form-fit element abut and/or overlap one another whereby the housing shell unit seamlessly surrounds the magnet unit without contacting the magnet unit.

2. The magnetic resonance apparatus as claimed in claim 1 , wherein the flexible foil material comprises a coincidence frequency of at least 5 kHz.

3. The magnetic resonance apparatus as claimed in claim 1 , wherein the flexible foil material comprises a surface density of at least 5 kg/m2.

4. The magnetic resonance apparatus as claimed in claim 1 , wherein the housing shell unit is positioned at a distance of at least 2 cm from the magnet unit.

5. The magnetic resonance apparatus as claimed in claim 1 , wherein the housing shell unit comprises at least one sound-absorbing absorption element which is disposed between the magnet unit and the housing shell unit.

6. The magnetic resonance apparatus as claimed in claim 1 , wherein the housing unit comprises a support frame which provides structure to the housing shell unit, the support frame being arranged around and spaced apart from the magnet unit, without contacting the magnet unit.

7. The magnetic resonance apparatus as claimed in claim 1 , wherein the housing unit comprises at least one bar-type attachment unit configured for attaching an inner surface the housing shell unit to an outer surface of the magnet unit.

8. The magnetic resonance apparatus as claimed in claim 1 , wherein the at least one first form-fit element and the at least one second form-fit element comprise either a snap-fit element or a friction-fit element.
