Description

[0001] The invention relates to a cable duct segment, a set of cable duct segments, a medical imaging system and a use of a cable duct segment or a set of cable duct segments.

[0002] Regardless of the grammatical gender of a particular term, it includes persons with male, female or other gender identities.

[0003] The operation of medical imaging systems, such as magnetic resonance imaging (MR) systems, requires a multitude of supply lines and cables. For magnetic resonance imaging systems, for example, it is common practice in the state of the art to route the cables along the ceiling. For this purpose, cables and lines are often routed in a so-called suspended ceiling. In conventional magnetic resonance imaging systems, a so-called "quench pipe" is also usually routed there. This pipe is used to remove explosively evaporating helium in the event of a quench of the superconducting magnet coil. The cables can then also be routed into the suspended ceiling parallel to the quench pipe.

[0004] Some more recently developed magnetic resonance imaging systems, however, require significantly reduced amounts of helium. This allows these systems to be designed with completely enclosed helium systems, thus no longer requiring a quench pipe. Therefore, it is desirable to find alternative ways to route the remaining cables and lines. One alternative is to route the lines in a false floor. However, a false floor can significantly increase installation costs, especially since MR systems are very heavy and are therefore preferably installed on solid floors. In addition, the magnet room is typically enclosed by a shielding radiofrequency cabin. Therefore, the rooms used often do not have a suitable false floor. Therefore, installing a false floor can entail considerable additional costs.It would therefore be desirable to find a way to simplify the provision of a cable or line routing for a medical imaging system.

[0005] It is therefore an object of the present invention to find an alternative to the cable and line routing of medical imaging systems, in particular magnetic resonance imaging systems. Preferably, a simplified and / or more cost-effective installation should be enabled.

[0006] This object is achieved by a cable duct segment according to claim 1, a cable duct segment according to claim 16, a set of cable duct segments according to claim 22, a medical imaging system according to claim 26 and a use according to claim 27. Further features and advantages emerge from the dependent claims, the description and the attached figures.

[0007] According to a first aspect of the invention, a cable duct segment is provided for routing cables and / or lines along a cable routing path on a floor. The cable duct segment comprises a cable routing area and a sleeve arranged at least partially around the cable routing area and running along the cable routing path for covering the guided cables or lines upwards, wherein the sleeve comprises a supporting layer and a cuttable layer. Advantageously, the cable duct segment can enable particularly simple installation of a cable line. In particular, several cable duct segments can be used to assemble a cable duct. Advantageously, the supporting layer can ensure the stability of the finished cable duct, while the cuttable layer can enable flexibility during installation. This flexibility can be achieved in particular with regard to the length of the finished cable duct.In principle, the desired or required stability and easy adjustment of the length of a cable duct can be difficult to achieve. On the one hand, a sufficiently stable material is required or at least desirable, but on the other hand, a stable material is generally difficult or even impossible to cut using simple means. Providing two layers can offer a solution here, as the load-bearing layer can ensure good stability. The problem of length adjustment can be solved on the one hand by providing cable duct segments that can be put together depending on the required length. With regard to fine adjustment, the problem of flexible length can be solved by using the cuttable layer. This does not have to be particularly load-bearing itself, but its length can be adjusted relatively easily, for example with the help of a knife.The cuttable layer is in particular easy to separate, e.g. by cutting or tearing, in particular transversely to the direction of the cable route. This allows a piece of the cuttable layer to be severed and removed. The severed piece of the cuttable layer can preferably be removed during installation without damaging the rest of the cable duct segment. When joining two cable duct segments, the length of the cuttable layer can be adjusted to the total length required. The two cable duct segments can then be joined together in such a way that in the area where the cable duct segments adjoin one another, two load-bearing layers, namely one from each cable duct segment, are pushed over one another. The cuttable layer of the two cable duct segments can be removed beforehand for this area.In addition, however, a portion of the cuttable layer can remain in each case, so that in an area where the two cable duct segments do not overlap, a load-bearing layer and a cuttable layer (from one cable duct segment) are arranged one above the other. This ensures that at least one load-bearing layer is present everywhere. The length, however, can be finely adjusted very easily, depending on how much of the cuttable layer is removed from the two cable duct segments. Stability can also be further increased by pushing the two cable duct segments together. Advantageously, with cable duct segments according to the invention, adaptation to local conditions, e.g. path lengths appropriate to the location, can be achieved using relatively simple means, e.g. with a simple cutting blade. Cable duct segments can advantageously be installed directly on a floor.This eliminates the need for a false floor. Furthermore, a relatively space-saving solution can be achieved, compared to, for example, a cable tower that runs cables to a ceiling. Furthermore, the cable duct on the floor allows the system to stand or be installed relatively freely in the room, which advantageously allows for more freedom in the system design.

[0008] The cable duct segment is a segment in particular in the sense that a cable duct can be provided from several cable duct segments. In this case, a cable routing area is used in particular to guide the cables and / or lines. The cable routing area can preferably be at least one hollow space which is at least partially enclosed by the casing and which extends in particular along the cable routing path. For this purpose, the casing is arranged at least partially around the cable routing area. A partial arrangement can mean, for example, that the casing is open towards the floor. The cables / lines are thus covered at least upwards by the casing. In this example, the cable line is then closed off at the bottom, in particular by a floor. The floor can preferably be a floor and / or the floor of a room, such as an examination room. The casing can therefore be open in one direction, in particular towards the floor.This can save material on the one hand. On the other hand, maintenance access to the wires / cables can be made easier. However, complete enclosure of the wires / cables by the sheath can also be advantageous in some embodiments. For example, complete enclosure can provide better protection for the wires / cables. Furthermore, complete enclosure can achieve better hygiene properties. For example, better or easier cleaning can be enabled. The susceptibility to liquids penetrating the cable duct can be reduced. Liquids can be, for example, bodily fluids such as blood, vomit, urine, etc.

[0009] The supporting layer can be made of a material that is less easy to cut than the material of the cuttable layer. Cuttability can in particular refer to the possibility of cutting the cuttable layer with a conventional tool knife. Cuttability and stability can, for example, be determined by the hardness of a material. The supporting layer can have a greater hardness than the cuttable layer. The hardness can, for example, be defined by a Shore A hardness. For example, the supporting layer can have a Shore A hardness of over 90. For example, the cuttable layer can have a Shore A hardness of less than 80. The exact absolute hardness of the layers can, however, vary, e.g. depending on the area of ​​application and available tools. The supporting layer can, for example, be made of hard plastic and / or glass fiber reinforced plastic.For example, the supporting layer can be designed to support a weight of up to 500 kg.

[0010] The cable duct segment can be provided with different dimensions. The dimensions can be adapted, in particular, depending on the intended use. The cable duct segment can, for example, have a width of 4 cm to 80 cm, preferably 20 to 60 cm, particularly preferably 30 cm to 50 cm. The cable duct segment can, for example, have a height of 3 cm to 30 cm, preferably 5 cm to 20 cm. These dimensions can be particularly favorable for routing lines / cables for medical imaging methods. A width of 30 cm to 50 cm and a height of 5 cm to 20 cm can be particularly favorable for the requirements of a magnetic resonance imaging system. The cable duct segment can, for example, have a length of 30 cm to 200 cm, preferably 40 cm to 150 cm. For example, cable duct segments with a length of approximately 50 cm or approximately 100 cm can be provided.Preferably, the thickness of the load-bearing layer and the cuttable layer can be substantially the same. This allows for particularly good and uniform joining of multiple cable duct segments. The thickness of the sheath can preferably be in the range of 3 to 12 mm, particularly preferably 5 to 7 mm. It has been shown that this thickness allows for a particularly good balance of load-bearing capacity, space savings, and flexibility in length adjustment.

[0011] According to one embodiment, the sleeve has an additional outer layer, wherein the cuttable layer and the supporting layer are arranged further inward and closer to the cable routing area than the outer layer. The outer layer can be advantageous in that it can enable additional properties of the cable duct segment without the inner layers having to be adapted accordingly. For example, the outer layer can enable a visual design of the cable duct segment, in particular without having to compromise on the properties of the other two layers. For example, the outer layer can be designed to prevent the penetration of liquids. This can be advantageous from a hygienic point of view. For example, the outer sleeve can enable easier cleaning and / or disinfection of an installed cable duct.For example, the outer sheath can be designed to be non-slip to prevent a person from slipping on the cable duct. For example, the outer sheath can be a film, particularly an adhesive film.

[0012] According to one embodiment, the casing comprises a flat cover section in a central region, viewed in the direction of the cable routing path. The cover section can be designed in particular such that, when the cable duct segment is installed on the floor, it runs essentially horizontally when viewed in the direction of the cable routing path. A flat cover section can enable cables to be routed in a particularly space-efficient manner. For example, the cable routing path can have an essentially rectangular cross-section in the region of the cover section. Within the scope of this invention, a cross-section of the cable duct segment is to be understood in particular such that the cable routing path runs perpendicularly through the cross-section.

[0013] According to one embodiment, the cover comprises a base section that runs substantially parallel to the cover section and is designed to rest on the floor during installation of the cable duct segment. A base section can also provide protection for the cables / wires downwards. For example, the cover can be designed to completely enclose the cable routing area in cross-section.

[0014] According to one embodiment, the casing comprises a lateral ramp in at least one edge region, preferably both edge regions, as viewed in the direction of the cable routing. The ramp preferably runs at an angle of 10° to 45°, preferably 25 to 35°, relative to the cover section. In particular, the lateral ramp can be provided in combination with the cover section and / or the base section. The ramp can have a surface that is essentially flat towards the outside. A lateral ramp, preferably two lateral ramps, can reduce the risk of tripping. In addition, driving over the cable duct with a trolley, for example, can be made easier. It is conceivable for the cable duct segment to have a ramp on only one side. For example, the cable duct segment can be rounded on the other side or designed to run vertically.A ramp on one side only can be advantageous, for example, if the cable duct is to run along a wall or other suitable structure.

[0015] According to one embodiment, the outer edges of the casing each comprise a vertical region which runs substantially perpendicular to the cover section, with the lateral ramp being arranged between the vertical region and the cover section. Advantageously, the vertical region can be designed to be recessed into a floor. For example, it can be provided that a corresponding recess is machined into the floor, e.g., milled. Advantageously, the vertical region can thus provide a relatively large amount of space for routing the cables / lines when used accordingly, although the cable duct can nevertheless protrude less or no higher into the room.

[0016] According to one embodiment, the vertical region has a vertical extension of 5 to 30, preferably 10 to 20, millimeters. For example, a height of 15 millimeters can be provided. This height has been shown to be particularly suitable because, on the one hand, it allows for relatively easy submersion in the ground and, on the other hand, a noticeable gain in space for the cables / wires can be achieved.

[0017] According to one embodiment, the cable duct segment comprises at least one partition, preferably at least two partitions, which run perpendicular to the cover section, in particular from the cover section to the base section, as viewed in the direction of the cable routing. The partitions can function as guide aids for the cables / lines. The partitions can advantageously enable an orderly and more clearly defined routing of the cables / lines. Preferably, the partitions can have a width of 4 to 15 millimeters, particularly preferably 5 to 10 millimeters, viewed in cross-section. With these dimensions, a good compromise between stability and space saving can be achieved. The at least one partition can comprise fastening elements for fastening the cables and / or lines. Fastening elements can, for example, be holes designed to allow cable ties to be passed through them.The at least two partition walls are preferably arranged symmetrically. The at least two partition walls are preferably arranged symmetrically, at least with respect to their position in the direction of the width of the cable duct. A symmetrical arrangement of the partition walls can be particularly advantageous when curved cable duct segments are provided. In particular, the curved cable duct segments can thus be used identically for both right-hand and left-hand bends.

[0018] According to one embodiment, the supporting layer is arranged further inside and closer to the cable routing area than the cuttable layer. According to a further embodiment, the cuttable layer is arranged further inside and closer to the cable routing area than the supporting layer. The further embodiment can be identical in particular to the one embodiment mentioned here in terms of its other features, with only the arrangement of the supporting and the cuttable layer being swapped. These two embodiments can complement each other particularly well. This is because when part of the cuttable layer is cut away in two cable duct segments, each according to a different one of the two embodiments, the two cable duct segments can be plugged together particularly well.

[0019] According to one embodiment, the cable routing path is curved, preferably at an angle of 5° to 45°, particularly preferably 10 to 20°, and most preferably 15°. Advantageously, a curved cable duct segment can also be used to create curvatures in the cable routing path. It has been shown that a curvature within the specified angle ranges can be particularly favorable for the properties of the cables / lines of medical imaging systems. An angle of 10 to 20° can be particularly well suited for the cables / lines of magnetic resonance imaging systems. For example, it can be provided to combine or assemble several curved cable routing paths in order to achieve a greater overall curvature. For example, with several cable duct segments curved by 15°, a total curvature of 45° (with 3 curved cable duct segments) or 90° (with 6 curved cable duct segments) can be achieved.

[0020] According to a further aspect of the invention, a cable duct segment is provided for guiding cables and / or lines along a cable routing path on a floor. The cable duct segment comprises a cable routing area and a sleeve arranged at least partially around the cable routing area and running along the cable routing path for covering the guided cables or lines upwards, wherein the sleeve comprises a supporting layer, wherein the supporting layer has at least one predetermined breaking point, preferably a plurality of predetermined breaking points, which is / are designed to enable the cable duct segment to be separated into two parts at a predefined location, preferably a plurality of predefined locations, along the cable routing path. The plurality of predetermined breaking points can preferably be arranged one behind the other, viewed in the direction of the cable routing path.The multiple predetermined breaking points enable flexible separation of the cable duct segment at various points defined by the predetermined breaking points. The variant with predetermined breaking points can be an alternative solution for flexible installation of a cable duct. The predetermined breaking points can, if necessary, enable even easier adjustment of the length. Optionally, the variant with predetermined breaking points can be combined with the variant with a load-bearing layer and a cuttable layer. The predetermined breaking point can optionally extend through the cuttable layer. For example, the cuttable layer can therefore be separated without the use of a knife. Alternatively, the predetermined breaking point can not extend into the cuttable layer. For example, the cuttable layer can thus prevent the cable duct segment from being accidentally separated.The cable duct segment according to this aspect can in principle also comprise the features of the cable duct segment with a load-bearing layer and the cuttable layer. All advantages and features of the cable duct segment with two layers can be transferred analogously to the cable duct segment with a predetermined breaking point and vice versa. This applies, for example, to the outer layer of the sheath. Preferably, the predetermined breaking point can be designed such that it does not extend into the outer layer. A predetermined breaking point that does not extend into the outer layer can have the advantage that, for example, liquids can be better contained by the outer layer. Furthermore, an outer layer that is not pre-separated can make a better visual impression. For example, it can be provided to separate the outer layer with a cutting knife at the point where the cable duct segment with the predetermined breaking point is to be separated into two parts.The cable duct segment according to this aspect can, for example, have a cover section as described herein. The cable duct segment according to this aspect can, for example, have a base section as described herein. The cable duct segment according to this aspect can, for example, have a lateral ramp, preferably two lateral ramps, as described herein. The cable duct segment according to this aspect can, for example, have a vertical region as described herein. The cable duct segment according to this aspect can, for example, have one or more partition walls as described herein. Optionally, the cable duct segment according to this aspect can be curved as described herein.

[0021] According to one embodiment, the at least one predetermined breaking point extends through the entire cross-section of the supporting layer, with the exception of an end region of the cross-section designed to rest on the ground. Advantageously, the end region through which the predetermined breaking point does not extend can result in improved stability. This allows for high strength with good length adaptability.

[0022] According to one embodiment, the at least one predetermined breaking point extends through the supporting layer in such a way that separating the cable duct segment into two parts creates a first part with a nose extending in the direction of the cable routing path and a second part with a complementary bulge. Advantageously, this embodiment allows two cable duct segments to be particularly well connected to one another after separation at the predetermined breaking point. This can, in particular, prevent two cable duct segments from pulling apart or slipping, e.g., after installation.

[0023] According to a further aspect of the invention, a cable duct segment is provided for guiding cables and / or lines along a cable routing path on a floor. The cable duct segment comprises a cable routing region and a sleeve arranged at least partially around the cable routing region and running along the cable routing path for covering the guided cables or lines upwards, wherein the sleeve comprises a supporting layer, wherein the sleeve, viewed in the direction of the cable routing path, comprises a flat cover section in a central region, wherein the sleeve comprises a vertical region at each of its outer edges, which runs essentially perpendicular to the cover section and is designed to be sunk into a floor. According to one embodiment, the sleeve comprises a lateral ramp in at least one edge region, preferably both edge regions, viewed in the direction of the cable routing path.The ramp preferably runs at an angle of 10° to 45°, preferably 25 to 35°, relative to the cover section. The lateral ramp can preferably be arranged between the vertical region and the cover section. Advantageously, the vertical region is intended to be recessed into a floor. For example, it can be provided that a corresponding recess is incorporated into the floor, e.g. by milling. Advantageously, when used accordingly, the vertical region can thus provide a relatively large amount of space for routing the cables / lines, whereby the cable duct can nevertheless protrude less or no higher into the room. All advantages and features of the cable duct segment according to the other aspects, the set of cable duct segments, the use and the medical imaging system can be transferred analogously to the cable duct segment according to this aspect and vice versa.

[0024] A further aspect of the invention is a set of cable duct segments comprising at least one cable duct segment as described herein, in which the supporting layer is arranged further inside and closer to the cable routing area than the cuttable layer, and at least one cable duct segment as described herein, in which the cuttable layer is arranged further inside and closer to the cable routing area than the supporting layer. All advantages and features of the cable duct segment can be transferred analogously to the set of cable duct segments, and vice versa. Advantageously, the two different embodiments of the cable duct segment allow particularly good flexible length adjustment of a cable duct. In particular, the two cable duct segments can be assembled in such a way that, in the area where the cable duct segments adjoin one another, two supporting layers, namely one from each cable duct segment, are pushed over one another.The different designs of the two cable duct segments mean that they can be assembled particularly well. Preferably, the load-bearing layers and the cuttable layers within a cable duct segment and beneath the two cable duct segments can be of equal thickness. The cuttable layer of each cable duct segment can be removed for this area before assembly. A portion of the cuttable layer can remain in each case, so that in an area where the two cable duct segments do not overlap, a load-bearing layer and a cuttable layer (from one cable duct segment) are arranged one above the other. Depending on the design of the two variants, the load-bearing layer is arranged on top in one area and the cuttable layer is arranged on top in the other area.Overall, this advantageously means that at least one load-bearing layer is present everywhere in the assembled cable duct. It can be provided that the set comprises even more cable duct segments. In particular, it can be provided that a cable duct can be flexibly assembled from several cable duct segments. It can be provided that all cable duct segments have a standardized, uniform length. The length is measured in particular in the direction of the cable routing. In one example, the cable duct segments can each be 1 meter long and a 1.7 meter long straight section is to be provided. In this case, for example, the cuttable layer of one of the cable duct segments can be cut from the inside with a knife at a point 70 cm from the end of the cable duct segment and then removed.For the second cable duct segment, the cuttable layer is cut from the outside at a point 30 cm from the end of the cable duct segment and also removed. The two cable duct segments can then be nested together, creating a continuously stable cable duct 1.7 meters long. Advantageously, this eliminates the need for a service technician, for example, to cut through the supporting layer. Therefore, a very stable, load-bearing (e.g., very hard) material can be used for the supporting layer, which does not require any on-site processing.

[0025] Particularly advantageously, the aspect of a cable duct segment with predetermined breaking points can be combined with the embodiment according to which the cable routing path is curved, preferably at an angle of 5° to 45°, particularly preferably 10 to 20°, and most preferably approximately 15°. The advantages and features described herein with regard to the curved cable duct segment can also be provided analogously in this aspect. The combination of the predetermined breaking points with the curved cable routing path can be particularly advantageous because in this combination, angles can be selected particularly flexibly, depending on which angle is currently required. For this purpose, it may be sufficient to simply separate the curved cable duct segment from a plurality of predetermined breaking points at the corresponding predetermined breaking point. This allows local requirements to be met particularly well.

[0026] According to one embodiment, the set further comprises at least one cable duct segment with a predetermined breaking point as described herein. Advantageously, the advantages of both variants can thus be combined. For example, the cable duct segment can be provided with predetermined breaking points for an end section of the cable duct. In particular, the cable duct segment can have a plurality of predetermined breaking points, whereby a fine adjustment of the length can be achieved. The main part of the cable duct can, on the other hand, be formed with cable duct segments without predetermined breaking points in order to provide a particularly stable main part. In this case, it can be advantageous to also be able to design this main part flexibly, for example, in order to be able to place curves at a desired location.

[0027] According to one embodiment, the set further comprises at least one cable duct segment whose cable routing path is curved, in particular as described herein. Advantageously, the set can thus also be used to create a cable duct having one or more curved sections.

[0028] A further aspect of the invention is a medical imaging system comprising a cable duct assembled from cable duct segments or a set of cable duct segments as described herein. The medical imaging system can, in particular, be a magnetic resonance imaging system. All advantages and features of the cable duct segment and the set of cable duct segments can be transferred analogously to the medical imaging system, and vice versa. In particular, for a magnetic resonance imaging system without a quench pipe, a particularly easy-to-install, yet stable, alternative for a cable line can thus be provided.

[0029] A further aspect of the invention is the use of a cable duct segment and / or a set of cable duct segments as described herein for installing a medical imaging system, in particular a magnetic resonance imaging system. All advantages and features of the cable duct segment, the set of cable duct segments, and the medical imaging system can be applied analogously to the use, and vice versa.

[0030] All embodiments described herein can be combined with one another unless explicitly stated otherwise.

[0032] Fig. 1 shows a cross-section of a cable duct segment 1 for guiding cables 10 and / or lines 11 along a cable routing path on a floor according to one embodiment of the invention. The cable duct segment 1 comprises a cable routing area 9 and a sleeve arranged at least partially around the cable routing area and running along the cable routing path for covering the guided cables 10 or lines 11 upwards. In this embodiment, the sleeve comprises a load-bearing layer 2 and a cuttable layer 3 and an outer layer 4. The cuttable layer 3 and the load-bearing layer 2 are arranged further inward and closer to the cable routing area 9 than the outer layer 4. Furthermore, the cuttable layer 3 is arranged further inward and closer to the cable routing area 9 than the load-bearing layer 2. The load-bearing layer 2 is designed to bear the majority of the load and primarily ensure the stability of the cable bridge.The cuttable layer 3 is less stable than the supporting layer 2 and can be easily cut by hand, for example, with a cutting knife. Furthermore, the cable duct segment comprises several partition walls 5, namely four partition walls in this case, which run vertically or perpendicular to the floor, as seen in direction K of the cable routing.

[0033] Fig. Figure 2 shows a cross-section of a cable duct segment 1 for guiding cables 10 and / or lines 10 along a cable routing path on a floor according to an embodiment of the invention. This embodiment corresponds to the one shown in Fig. 1, however, differs in that here the supporting layer 2 is arranged further inside and closer to the cable guide area 9 than the cuttable layer 3. In other words, the arrangement of the supporting layer 2 and the cuttable layer is reversed. These two embodiments can therefore be combined particularly well to create a flexible cable duct, especially flexible in terms of length. The principle is shown in the Fig. 3 and Fig. 4 illustrates this.

[0034] Fig. Figure 3 shows a sectional view from the side of two cable duct segments 1, which may correspond to those shown in Fig. 1 and Fig. 2. For clarity, no cables 10, lines 11 and partition walls 5 are shown here. The viewing direction corresponds to that shown in the Fig. 1 and Fig. 2 is indicated. In each case, a portion of the cuttable layer has been cut away. Preferably, the cable duct segments 1 have a standard length in direction K of the cable route. In this case, a length of 1 meter is assumed, for example, and the goal is to create a combined piece with a length of 1.7 meters from two cable duct segments 1, each one meter long. To do this, a 30 cm long piece of the cuttable layer 3 is removed from both cable duct segments. In addition, the outer layer 4 is removed where it directly borders the cuttable layer 3, as is the case here in the left cable duct segment 1. This means that in the area where the cuttable layer 3 was removed, only the load-bearing layer 2 of the sheath remains in the left cable duct segment 1, and the load-bearing layer 2 with the outer layer 4 remains in the right cable duct segment.The two cable duct segments 1 are then pushed together so that the situation of . Fig. 4. The overall thickness of the casing is uniform throughout, and it is also ensured that the supporting layer 2 is present at least once along the entire cable route. Overall, a cable duct adjusted to a desired length (in this example, 1.7 meters) can be provided relatively easily, especially without the (usually hard) supporting layer 2 having to be cut or otherwise processed.

[0035] Fig. 5 shows a cross-section of a cable duct segment 1 for guiding cables 10 and / or lines 11 along a cable routing path on a floor according to a further embodiment of the invention. The cable duct segment 1 comprises a cable routing area 9 and a sheath arranged at least partially around the cable routing area and running along the cable routing path to cover the guided cables 10 or lines 11 upwards. In this embodiment, the sheath comprises a supporting layer 2 and a cuttable layer 3 and can also comprise an outer layer 4. These layers are not explicitly shown here, but can be arranged accordingly as in Fig. 1 or Fig. 2. The casing comprises, in a central region as viewed in the direction of the cable routing, a flat cover section 21 and a base section 22 which runs substantially parallel to the cover section 21 and is designed to lie on the base 30 when the cable duct segment 1 is installed. A plurality of partition walls 5 of the cable duct segment are also provided, namely in this case two partition walls 5 which, as viewed in the direction K of the cable routing, run perpendicular to the cover section 21 from the cover section 21 to the base section 22. Furthermore, the casing comprises, in each of its two edge regions as viewed in the direction K of the cable routing, a lateral ramp 23. The ramps 23 run at an angle W of approximately 30° relative to the cover section 21.Furthermore, in this embodiment, the cover optionally comprises a vertical region 24 on each of its outer edges, which runs substantially perpendicular to the lid section 21, wherein the lateral ramps 23 are each arranged between the vertical region 24 and the respective lid section 21. The vertical region 24 is intended to be recessed into a base 30. This is shown in FIG. Fig. 6. For this purpose, a corresponding recess is machined into the base 30, e.g., by milling.

[0036] Fig. Figure 7 shows a cross section of a cable duct segment 1 for guiding cables 10 and / or lines 11 along a cable routing path on a floor according to a further embodiment of the invention. A corresponding sectional view from the side is shown in Fig. 8. The cable duct segment comprises a cable guide area 9 and a sheath arranged at least partially around the cable guide area and extending along the cable routing path to cover the guided cables 10 or lines 11 upwards. The sheath comprises a supporting layer. As shown in Fig. As shown in Figure 8, the supporting layer 2 has a plurality of predetermined breaking points 41 designed to enable the cable duct segment 1 to be separated into two parts at one of several predefined locations (according to the predetermined breaking points 41) along the cable routing path. The predetermined breaking points extend through an entire cross-section of the supporting layer 2, with the exception of an end region 42 of the cross-section designed to rest on the floor.

[0037] It is optionally possible to connect the variant with predetermined breaking points with the one with a cuttable layer 3, e.g. as in Fig. 1 and Fig. 2. This is shown in Fig. Figure 9 illustrates where the cable duct segment has a supporting layer 2, a cuttable layer 3, and an outer layer 4. In this embodiment, the predetermined breaking points 41 do not extend through the outer layer 4. This can be cut off accordingly, e.g., with a knife. This has the advantage that no predetermined breaking points are visible from the outside. This can prevent, for example, the penetration of liquids. It can also be provided that only the supporting layer 2 and the outer layer 4, or only the supporting layer 2 and the cuttable layer 3, are present.

[0038] Optionally, the predetermined breaking points 41 can extend through the supporting layer 2 (or one or more further layers) in such a way that the separation of the cable duct segment into two parts produces a first part with a nose extending in the direction of the cable routing path and a second part with a complementary bulge. One possible embodiment of this type is shown in Fig. 10. This shows a cable duct segment in a top view, with the path of the predetermined breaking points 41 indicated by dashed lines. For example, the predetermined breaking points 41 can be provided at intervals of 5 cm in direction K of the cable routing.

[0039] Fig.Figure 11 shows a medical imaging system, for example, a magnetic resonance imaging system, with a cable duct assembled from cable duct segments 1 according to an embodiment of the invention. The cable duct segments 1 may, for example, correspond to those shown in the other figures.
