Embodiment Construction

[0028] figure 1 A schematic diagram of a magnetic resonance apparatus 10 according to the invention is shown. The magnetic resonance device 10 includes a magnet unit 11 with a main magnet 12 for generating a strong and in particular constant main magnetic field 13 . In addition, the magnetic resonance apparatus 10 has a cylindrical receiving region 14 for receiving a patient 15 , wherein the receiving region 14 is surrounded in the peripheral direction by the magnet unit 11 . The patient 15 can be pushed into the receiving area 14 by means of a patient couch 16 of the magnetic resonance apparatus 10 . The patient couch 16 is here displaceably arranged inside the magnetic resonance system 10 . In addition, the magnetic resonance device 10 has a housing unit 30 surrounding the magnet unit 11 .

[0029] Furthermore, magnet unit 11 has gradient coils 17 for generating magnetic field gradients, which are used for position encoding during imaging. The gradient coils 17 are contr...

Abstract

The invention relates to a high-frequency coil arrangement for a magnetic resonance device and to a magnetic resonance device with a high-frequency coil arrangement. The high-frequency coil arrangement has a receiving area and structural elements for receiving a patient. The flexible surface element extends between the rib elements and surrounds the receiving area. A high-frequency structure is arranged on the structural element.

Description

technical field [0001] The invention relates to a high-frequency coil arrangement for a magnetic resonance system, which has a receiving region for receiving a patient, and to a magnetic resonance system with a high-frequency coil arrangement according to the invention. Background technique [0002] During operation, magnetic resonance systems have high operating noises, which can have an uncomfortable effect on patients who remain in the receiving area of ​​the magnetic resonance system for examinations. In particular, large vibration amplitudes occur on the area of ​​the high-frequency coil arrangement surrounding the patient receiving area, which has the consequence of high noise radiation to the patient. In addition, acoustic resonances may occur in the accommodation area, which may represent an additional noise load. Typical magnetic resonance devices have rigid and fixedly mounted housing shell units, which have high noise emissions. [0003] From the publication DE ...
