In particular, the device comprises a lying surface, for example a treatment couch. In a further embodiment it is provided that the device is in particular an imaging device. According to one embodiment, the device is selected from a group comprising at least a magnetic resonance tomograph, a computed tomography device, an x-ray device such as an x-ray tomograph, an ultrasound device, a nuclear spin tomograph, a scintigrapher, an impedance tomograph, an endoscopy device and / or a thermograph. In a further embodiment, the device may comprise an EEG and / or devices for carrying out a stress ECG.

Imaging means are in particular projectors such as video projectors, which may be configured as LCD, DLP or tube projectors. In a further embodiment, the imaging means are laser projectors. It is further provided according to an embodiment that the imaging means are electronically controlled and in particular by means of a computer system or a computer network can be controlled. The imaging means are preferably arranged such that the projections of these project a substantially seamless, more preferably overlapping image on at least the top and / or side surface, preferably on the top surface and both side surfaces, optionally also on the back surface of the room. In a further embodiment it is provided that at least one image is projected on the floor and / or the ceiling, which preferably is substantially seamlessly adjacent to the images on the side surfaces or the head surface. The all-round projection includes in particular a From about 1 70 ° to about 360 °, more preferably about 1 80 ° to about 270 ° starting from the centroid of the base of the room, in a further embodiment, starting from the centroid of the base of the device, in a further embodiment, starting from a Coil center of the device designed as a magnetic resonance tomograph. It is further preferred in one embodiment that at least the top surface and at least parts of the side surfaces, preferably the entire side surfaces are illuminated by the imaging means. The moving images may in particular be videos, photo sequences and / or animated and / or rendered images and / or films. Particularly preferably, the moving images are projected onto the head and side surfaces and possibly the back surface, the ceiling and / or the floor in such a way that the impression arises that the patient is in the scene of the video or in the moving pictures.

In one embodiment, the all-round projection is produced by projections of the individual imaging means which adjoin each other in particular. The all-round projection is essentially seamless in one embodiment. The projections of the individual imaging agents preferably adjoin one another substantially seamlessly. In one embodiment, it is provided that at least one projection of at least one imaging device adjoins at least one corner between a side surface and a head surface.

In a further preferred embodiment, the projections are matched to one another in such a way that they produce a coherent, especially moving image. More preferably, the projections are image sections which are assembled by means of the all-round projection. In a further embodiment it is provided that the all-round projection is synchronized. In particular, an image sequence is synchronized such that the individual projections always result in a coherent image when the projected image changes. In one embodiment, the all-round projection is matched to the side surfaces and the top surface, so that this results in a panorama, which in particular promotes space.

The term "substantially" indicates a tolerance range which is to be represented for the skilled person from an economic and technical point of view, so that the corresponding feature can still be recognized or realized as such.

The advantage of the proposed arrangement is that in particular soothing moving images, preferably video sequences, have a calming effect on them before and during the treatment or examination of the patient. The fact that the patient sees himself surrounded by the moving images, this leads to a very calm, meditative and / or hypnotic state of consciousness, which greatly facilitates the treatment and / or examination of the patient. In particular, children undergoing an MRI scan often need to be sedated to withstand the stress of the MRI and, in particular, to remain silent. In particular, the tightness in a magnetic resonance tomograph and the loud noises often lead to anxiety and thus to reactions that make it impossible to remain silent. Through the moving images, a feeling of width can be generated and the patient to be examined or treated is calmed down even before the actual examination, so that in many cases sedation is no longer necessary. In a further embodiment, it is provided that the device comprises a lying surface for at least one patient, and further preferably has an arranged in an angular range of about 35 ° to about 60 ° to the lying surface and in particular adjustable mirror, by means of which a projected onto the head surface moving Picture at least in a section for the patient lying easy, especially without movement of the head, is visible.

FIG. 2 shows a further sketch of the arrangement in a side view; FIG. and Fig. 3 is a further sketch of the arrangement in a front view.

1 shows a sketch of the arrangement 10 according to the invention in a plan view, wherein a space 40 can be seen, which comprises a top surface 39 and two side surfaces 41 .1 and 41 .2. In the space 40 is a device 20, which is designed as a magnetic resonance tomograph with a coil center 26. Furthermore, FIG. 1 shows that imaging means 70.1 to 70.7 are part of the arrangement 10.

As can be seen in FIG. 2, the imaging means 70. 1 to 70. 7 are arranged in a suspended ceiling 50. The imaging means 70.1 to 70.7 are configured in particular as projectors or beamers, wherein, as can be seen from FIG. 1, the imaging means 70.1 and 70.5 project onto the head surface 39, which project the imaging means 70.7 and 70.2 onto the side surface 41.1 , the imaging means 70.3 and 70.6 on the side surface 41 .2 project and the imaging means 70.4 on an end face 24 of the device 20 projects. It is preferably provided that moving images such as videos or rendered films are projected onto the head surface 39 and the side surfaces 41 .1 and 41 .2 by means of the imaging means 70.1 to 70.7 in such a way that a seamless, in particular continuous all-round projection of moving images is produced. Furthermore, the projection of the moving images onto the end face of the device 20 is designed such that it integrates optically into the projection of the moving images onto the top surface 39 and the side surfaces 41, 1 and 41, 2. In an exemplary embodiment, a space flight simulation is projected onto at least the top surface 39 and parts of the side surfaces 41 .1 and 41 .2, preferably on the entire side surfaces 41 .1 and 41 .2. On the front surface 24 is then exemplified a spiral galaxy, preferably with an owl, projected.

The imaging means 70.1 to 70.7 are arranged in electromagnetically shielded housings 62.1 to 62.5. These largely prevent the effects of a magnetic field, which is generated by the magnetic resonance tomograph, on the imaging means 70.1 to 70.7. The device 20 has a lying surface 22, which in turn comprises two longitudinal sides 32.1 and 32.2. The long sides 32.1 and 32.2 are to the Seitenflä- Chen 41 .1 and 41 .2 arranged approximately parallel. As can also be seen in FIG. 1, the space 40 has a door 66, through which the space 40 can be entered. In a further, not shown embodiment, it is also provided that the wall, which has the door is also recorded from the inside and / or outside with moving images, preferably seamlessly inserting into the moving images on the side walls 41 .1 and 42.2 , The space may be illuminated by lights 68 disposed in the panel 53 of the suspended ceiling 50. The room also has a closet 64, in which an exhaust pipe 60 is arranged. FIG. 2 shows a side view of the arrangement 10, from which it can be seen that the space 40 is arranged between a lower floor 42 and an upper ceiling 44. Furthermore, Fig. 2 it can be seen that a suspended ceiling 50 is provided, which is largely completed by a false ceiling 52 downwards and having a cavity. The suspended ceiling 50 is suspended with anchors 56 which hold the suspended ceiling 50 on the top cover 44. More preferably, the electromagnetically shielded housing 62.1 to 62.5 are held indirectly or directly by the anchors 56. Furthermore, it can be seen that in a region of recesses 54, the shielded housings 62.1 to 62.5 are arranged with the imaging means 70.1 to 70.7. The imaging means 70.1 to 70.7 are horizontal, ie horizontal. So that they can project onto the projection surfaces, that is to say the top surface 39 and the side surfaces 41 .1 and 41 .2 and the end surface 24 of the device 20, they have an oblique projection device which, despite the horizontal arrangement of the imaging means 70.1 to 70.7 Radiation or projection of the moving images downwards allows. The imaging means 70.1 to 70.7 are furthermore arranged in such a way that a projector lens of the imaging means (not further described here) is arranged approximately at the level of the upwardly displacing intermediate ceiling 52. Both the upwardly suspended false ceiling 52 and the electromagnetically shielded housings 62.1 to 62.5 have openings through which can be projected. A quench tube 28 is passed under the top cover 44 to above the device 20 and then by the suspended de 50 passes through the device 20. It can also be seen that the exhaust pipe 60 is guided in the suspended ceiling 52.

The device 20 is anchored to the topsoil 46. For electromagnetic shielding of the rooms located below the room 40, an electromagnetic shielding support is applied to the upper side 48 of the upper floor 46.

Furthermore, it can also be seen from FIG. 3 that large recesses 54 are arranged in the false ceiling 52 and the cladding 53, which allows projection onto the top surface 39 and the side surfaces 41, 1 and 41, 2. The imaging means, here exemplified 70.5, are arranged in the electromagnetically shielded housing 62.4. The Fig. 3 can also be seen that above the suspended ceiling 50 insulating material 58 is arranged, which provides in particular for noise insulation to other adjacent rooms. A similar insulation can also be arranged in the side walls.

Furthermore, it can be seen from FIG. 3 that the device 20 has a coil center 26 and an end face 24 which has at least one projection surface 25. The device 20 further comprises a mirror 30. The mirror 30 is arranged adjustable at an angle of about 35 ° to about 60 ° to the lying surface. The patient lying on the lying surface 22 can look at the head surface 39 during the examination by means of the mirror 30 and continue to follow the moving images there.

Both FIG. 2 and FIG. 3 it can be seen that the magnetic field lines emanating from the magnetic resonance tomograph during the examination of a patient, by the false ceiling 52 and / or by the electromagnetically shielded housings 62.1 to 62.5 are shielded such that the imaging Means 70.1 to 70.7 are exposed to a magnetic field of less than 3 mT. This ensures that the special electronic projectors without significant distortion by the magnetic field can cast an image on the projection surfaces.
