Embodiment Construction

[0024] figure 1 A longitudinal section through a rail vehicle 1 according to the invention is shown schematically. In the exemplary embodiment shown, an examination room 10 with a magnetic resonance tomography system 20 is arranged centrally within the rail vehicle 1 . The advantage of this central arrangement is that the technical energy supply devices 30 , 40 , 50 can be arranged on the side of the examination room facing away from the patient preparation room 70 and operating room 60 , and the patient does not have to pass by the device in order to reach the examination room 10 . The security requirements for such separated technical spaces are lower than for public accessible spaces. Thus, the patient and the operator are also easily protected from the noise and heat generated by the energy supply device 30 , 40 , 50 .

[0025] The magnetic resonance tomography system 20 is surrounded by a magnetic shield 11 whose task is to reduce the fringe fields generated by the magn...

Abstract

A railroad car for the accommodation and operation of a magnetic resonance tomography is provided. The railroad car includes a magnetic shielding of a volume for accommodation of the magnetic resonance tomograph. The magnetic shielding is designed to limit a magnetic scatter field outside a volume surrounded by the magnetic shielding to a value which is not hazardous to the environment, when a magnetic resonance tomograph is performing an examination in the interior of the volume.

Description

technical field [0001] The invention relates to a rail vehicle for receiving and operating a magnetic resonance tomograph, and to such a rail vehicle with a magnetic resonance tomograph. Background technique [0002] Magnetic resonance tomography has become an important aid in the diagnosis of many diseases in recent years. The magnetic resonance tomography system relates in particular to organs and tissues, such as the brain, which are poorly imaged due to the smaller contrast differences when imaging with x-rays. [0003] On the other hand, magnetic resonance tomography systems have larger dimensions and a greater weight than x-ray systems due to the required magnetic fields and the magnets and energy supply devices required to generate them. [0004] Furthermore, the sensitivity of the measurement methods used to magnetic field disturbances requires shielding measures with the external surroundings and careful preparation of the location. On the other hand, the regulati...
