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, persons with male, female or other gender identities are included.

[0003] Operating medical imaging systems, such as magnetic resonance imaging (MRI) systems, requires a multitude of cables and conduits. In current technology, it is common practice to run these cables and conduits along the ceiling. This often involves routing them through a suspended ceiling. In typical MRI systems, a quench pipe is also usually installed in this suspended ceiling. This pipe serves to vent the helium that would otherwise vaporize explosively if the superconducting magnet coil were to quench. The cables can then be routed into the suspended ceiling parallel to the quench pipe.

[0004] Some newly developed magnetic resonance imaging (MRI) systems, however, require significantly reduced amounts of helium. This allows these systems to be designed with completely closed helium chambers, thus eliminating the need for a quench pipe. Against this backdrop, it is desirable to find alternative methods for routing the remaining cables and wires. One alternative is to run the cables in a raised floor. However, a raised floor can considerably increase the installation effort, especially since MRI systems are very heavy and therefore preferably installed on solid floors. Furthermore, the magnetic resonance chamber is typically enclosed by a shielding radio frequency cabinet. The rooms used often lack a suitable raised floor. Therefore, installing a raised floor can entail significant additional costs.It would therefore be desirable to find a way to simplify the provision of cable or conduit routing for a medical imaging system.

[0005] An installation device for installing conduits is disclosed in EP 2 515 400 B1, wherein the installation device is intended to advantageously install electrical conduits and / or cables within a building. For this purpose, the installation device has a grid structure which serves to support conduits and / or cables.

[0006] Furthermore, a cable laying system is known from DE 10 2015 206 181 A1. This cable laying system is suitable for laying cables and has a modular channel structure. The channel structure comprises an internal cable laying channel system consisting of interconnected cable laying channels.

[0007] German patent application DE 10 2019 107 419 A1 discloses a cable bridge for protecting cables. The cable bridge comprises a base body with at least one longitudinally extending and upwardly open channel for receiving a cable. The cable bridge also includes a cover pivotably attached to the base body for covering the channel.

[0008] DE 69 702 691 T2 describes a cable carrier for attaching electrical cables using cable ties, wherein the cable carrier consists of a folded and cut sheet metal. The sheet metal includes a mounting wall designed to be attached to a support surface. The sheet metal also includes a suspension section with several slots, the slots being designed to receive the cable ties.

[0009] It is therefore an object of the present invention to find an alternative to the cable and wiring of medical imaging systems, in particular magnetic resonance imaging systems. Preferably, this should enable a simplified and / or more cost-effective installation.

[0010] This problem is solved by a cable duct segment according to claim 1, a cable duct segment according to claim 11 or 21, a set of cable duct segments according to claim 22, a medical imaging system according to claim 25, and a use according to claim 27. Further features and advantages will become apparent from the dependent claims, the description, and the accompanying figures.

[0011] According to a first aspect of the invention, a cable duct segment is provided for guiding cables and / or conduits along a cable routing path on a floor. The cable duct segment comprises a cable routing area and a cover, arranged at least partially around the cable routing area and extending along the cable routing path, for covering the guided cables or conduits upwards, wherein the cover comprises a load-bearing layer and a cuttable layer. Furthermore, the cover has an additional outer layer, wherein the cuttable layer and the load-bearing layer are arranged further inwards and closer to the cable routing area than the outer layer. Advantageously, the cable duct segment enables particularly simple installation of a cable conduit. In particular, several cable duct segments can be used to assemble a cable duct.Advantageously, the load-bearing layer can ensure the stability of the finished cable duct, while the cuttable layer allows for flexibility during installation. This flexibility is particularly important with regard to the length of the finished cable duct. Achieving the desired or required stability and easy length adjustment of a cable duct can be challenging. On the one hand, a sufficiently stable material is needed or at least desirable; on the other hand, stable materials are usually difficult or even impossible to cut using simple tools. The use of two layers can offer a solution here, as the load-bearing layer provides good stability. The problem of length adjustment can be solved by using cable duct segments that can be assembled as needed.Regarding fine-tuning, the issue of flexible length can be solved using a cuttable layer. This layer itself does not need to be particularly load-bearing, but its length can be adjusted relatively easily, for example, with a knife. The cuttable layer is particularly easy to sever, for example, by cutting or tearing, especially perpendicular to the direction of the cable routing. This allows a section of the cuttable layer to be separated and removed. The separated section of the cuttable layer is preferably removable during installation without damaging the rest of the cable duct segment. When joining two cable duct segments, the length of the cuttable layer can then be adjusted to match the total length required.The two cable duct segments can then be joined in such a way that, in the area where they connect, two load-bearing layers—one from each segment—are overlapped. The cuttable layer of each segment can be removed beforehand. Additionally, a portion of the cuttable layer can remain, so that in areas where the two segments do not overlap, one load-bearing layer and one cuttable layer (from one segment) are stacked on top of each other. This ensures that at least one load-bearing layer is present everywhere. The length can be easily and precisely adjusted by removing the amount of cuttable layer from each segment. Furthermore, the stability is increased by sliding the two segments together.Advantageously, the cable duct segments according to the invention can be adapted to local conditions, e.g., to specific path lengths, using relatively simple means, such as a simple cutting blade. Advantageously, the cable duct segments can be installed directly on a floor, eliminating the need for an intermediate floor. Furthermore, a relatively space-saving solution can be achieved, for example, compared to a cable tower that routes cables to a ceiling. Additionally, the system can be positioned relatively freely within the room due to the cable duct on the floor, thus advantageously allowing for greater design freedom.

[0012] The cable duct segment is a segment in that several cable duct segments can be combined to form a complete cable duct. A cable guide area serves, in particular, to guide the cables and / or conduits. The cable guide area can preferably be at least a cavity partially enclosed by the casing, extending along the cable routing path. For this purpose, the casing is arranged, at least partially, around the cable guide area. A partial arrangement can, for example, mean that the casing is open towards the bottom. The casing thus covers the cables / conduits at least from above. In this example, the cable run 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 designed to be open in one direction, in particular towards the bottom.This allows for material savings. Furthermore, it facilitates maintenance access to the cables. However, in some designs, completely enclosing the cables can also be advantageous. For example, complete enclosure can provide better protection for the cables. It can also improve hygiene, allowing for easier cleaning. Additionally, it can reduce the risk of liquids penetrating the cable duct. These liquids could include bodily fluids such as blood, vomit, urine, etc.

[0013] The supporting layer may be made of a material that is less easily cut than the material of the cuttable layer. Cuttableness, in this context, refers specifically to the ability to cut the cuttable layer with a standard utility knife. Cuttableness and stability can be determined, for example, by the hardness of a material. The supporting layer may have a greater hardness than the cuttable layer. Hardness can be defined, for example, by its Shore A hardness. For instance, the supporting layer may have a Shore A hardness greater than 90, while the cuttable layer may have a Shore A hardness less than 80. However, the exact absolute hardness of the layers can vary, depending on factors such as the application and available tools. The supporting layer may, for example, be made of hard plastic and / or glass fiber reinforced plastic.For example, the load-bearing layer can be designed to support a weight of up to 500 kg.

[0014] The cable duct segment can be provided with various dimensions. The dimensions can be adapted, in particular, depending on the intended use. For example, the cable duct segment can have a width of 4 cm to 80 cm, preferably 20 cm to 60 cm, and 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 advantageous for routing cables for medical imaging procedures. A width of 30 cm to 50 cm and a height of 5 cm to 20 cm can be particularly advantageous for the requirements of a magnetic resonance imaging (MRI) 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 essentially the same. This allows for particularly good and uniform joining of multiple cable duct segments. The overall thickness of the casing is preferably in the range of 3 to 12 mm, and more preferably 5 to 7 mm. It has been shown that this thickness achieves a particularly good balance between load-bearing capacity, space saving, and flexibility in length adjustment.

[0015] According to the invention, the casing has an additional outer layer, wherein the cuttable layer and the load-bearing layer are arranged further inwards 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 requiring corresponding adjustments to the inner layers. For example, the outer layer can allow for a more aesthetically pleasing design of the cable duct segment, particularly without compromising the properties of the other two layers. For example, the outer layer can be designed to prevent the ingress of liquids. This can be advantageous from a hygienic point of view. For example, the outer casing can facilitate easier cleaning and / or disinfection of an installed cable duct.For example, the outer casing can be designed to be non-slip to prevent a person from slipping on the cable duct. For example, the outer casing can be a film, especially an adhesive film.

[0016] According to one embodiment, the casing, viewed in the direction of the cable routing, comprises a flat cover section in a central area. 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. A flat cover section allows for particularly space-efficient cable routing. For example, the cable routing in the area of ​​the cover section can have a substantially rectangular cross-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 runs perpendicularly through the cross-section.

[0017] According to one embodiment, the casing includes a base section that runs essentially parallel to the cover section and is designed to lie on the floor when the cable duct segment is installed. A base section can also provide protection for the cables / conduits from below. For example, the casing may be designed to completely enclose the cable routing area in cross-section.

[0018] According to one embodiment, the casing, viewed in the direction of the cable routing, includes a lateral ramp in at least one edge region, preferably in both edge regions. Preferably, the ramp runs at an angle of 10° to 45°, more 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 substantially flat surface on the outside. A lateral ramp, preferably two lateral ramps, can reduce the risk of tripping. Furthermore, it can facilitate driving over the cable duct with, for example, a trolley. It is conceivable that the cable duct segment has a ramp on only one side. For example, the cable duct segment can be rounded or vertical on the other side.A ramp on only one side can be advantageous, for example, if the cable duct is to run along a wall or other similar structure.

[0019] According to one embodiment, the casing comprises a vertical section at each of its outer edges, which extends substantially perpendicular to the lid section, with the lateral ramp being arranged between the vertical section and the lid section. Advantageously, the vertical section can be designed to be recessed into a floor. For example, a corresponding recess can be incorporated into the floor, e.g., by milling. Advantageously, the vertical section, when used appropriately, can thus provide a relatively large amount of space for routing the cables / conduits, while the cable duct can still protrude less high or not protrude any further into the room.

[0020] According to one embodiment, the vertical section has a length of 5 to 30 millimeters, preferably 10 to 20 millimeters. For example, a length of 15 millimeters can be provided. This height has proven particularly suitable because it allows for relatively easy embedding in the ground and also provides a noticeable gain in space for the cables / conduits.

[0021] According to one embodiment, the cable duct segment comprises at least one partition, preferably at least two partitions, which, viewed in the direction of the cable routing, extend perpendicular to the cover section, particularly from the cover section to the base section. The partitions can act as guides for the cables / conductors. Advantageously, the partitions enable a more organized and clearly defined routing of the cables / conductors. Preferably, the partitions have a cross-sectional width of 4 to 15 millimeters, particularly preferably 5 to 10 millimeters. These dimensions allow for a good compromise between stability and space efficiency. The at least one partition can include fastening elements for securing the cables and / or conductors. Fastening elements can, for example, be holes designed to allow cable ties to pass through them.The at least two partitions are preferably arranged symmetrically. The at least two partitions 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 partitions can be particularly advantageous when curved cable duct segments are used. In particular, the curved cable duct segments can thus be used identically for both right and left curves.

[0022] According to one embodiment, the load-bearing layer is arranged further inwards and closer to the cable routing area than the cuttable layer. According to another embodiment, the cuttable layer is arranged further inwards and closer to the cable routing area than the load-bearing layer. This further embodiment can be identical to the one embodiment mentioned here, particularly in its other features, except that the arrangement of the load-bearing and cuttable layers is reversed. These two embodiments can complement each other particularly well. This is because, when a portion of the cuttable layer is removed from two cable duct segments according to one of the other embodiments, the two cable duct segments can be joined together particularly well.

[0023] According to one embodiment, the cable channel is curved, preferably by an angle of 5° to 45°, particularly preferably 10° to 20°, and most preferably 15°. Advantageously, curved cable channel segments can also be used to achieve different curvatures of the cable channel. It has been shown that a curvature in the specified angle ranges can be particularly beneficial for the properties of cables / conductors in medical imaging systems. An angle of 10° to 20° can be particularly well suited for the cables / conductors of magnetic resonance imaging systems. For example, it may be possible to combine or join several curved cable channels to achieve a greater overall curvature. For example, several cable channel segments curved by 15° can achieve a total curvature of 45° (with 3 curved cable channel segments) or 90° (with 6 curved cable channel segments).

[0024] According to a further aspect of the invention, a cable duct segment is provided for guiding cables and / or wires along a cable routing path on a floor. The cable duct segment comprises a cable routing area and a cover, arranged at least partially around the cable routing area and extending along the cable routing path, for covering the guided cables or wires upwards. The cover comprises a load-bearing layer, the load-bearing layer having at least one predetermined breaking point, preferably several predetermined breaking points, configured to allow the cable duct segment to be separated into two parts at a predefined location, preferably several predefined locations, along the cable routing path. Preferably, the multiple predetermined breaking points can be arranged one after the other in the direction of the cable routing path.The multiple predetermined breaking points allow for flexible separation of the cable duct segment at various locations defined by these points. This variant with predetermined breaking points can be an alternative solution for flexible cable duct installation. The predetermined breaking points can also facilitate even easier length adjustments. Optionally, the variant with predetermined breaking points can be combined with a variant featuring a load-bearing layer and a cuttable layer. The predetermined breaking point can optionally extend through the cuttable layer, allowing the cuttable layer to be separated without a knife. Alternatively, the predetermined breaking point can be excluded from the cuttable layer, preventing accidental separation of the cable duct segment.The cable duct segment, according to this aspect, can in principle also include the features of the cable duct segment with a load-bearing layer and the cuttable layer. All advantages and features of the two-layer cable duct segment 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 casing. Preferably, the predetermined breaking point can be designed so 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 unpre-separated outer layer can create a more aesthetically pleasing appearance. For example, it can be provided that the outer layer is cut with a cutting blade 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 bottom 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 section as described herein. The cable duct segment according to this aspect can, for example, have one or more partitions as described herein. Optionally, the cable duct segment according to this aspect can be curved as described herein.

[0025] According to one embodiment, the at least one predetermined breaking point extends through an entire cross-section of the load-bearing 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 provide better stability. This allows for high strength with good adaptability of the length.

[0026] 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 produces a first part with a tab 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 joined particularly well to each other at the predetermined breaking point after separation. This prevents, in particular, the two cable duct segments from being pulled apart or slipping, e.g., after installation.

[0027] According to a further aspect of the invention, a cable duct segment is provided for guiding cables and / or wires along a cable routing path on a floor. The cable duct segment comprises a cable routing area and a cover, arranged at least partially around the cable routing area and extending along the cable routing path, for covering the guided cables or wires upwards. The cover comprises a load-bearing layer and, viewed in the direction of the cable routing path, includes a flat cover section in a central region. The cover also includes a vertical region at each of its outer edges, which extends substantially perpendicular to the cover section and is designed to be recessed into a floor. According to one embodiment, the cover, viewed in the direction of the cable routing path, includes a lateral ramp in at least one edge region, preferably in both edge regions.Preferably, the ramp slopes at an angle of 10° to 45°, more preferably 25° to 35°, relative to the cover section. The lateral ramp can preferably be positioned between the vertical section and the cover section. Advantageously, the vertical section is designed to be recessed into the floor. For example, a corresponding recess can be milled into the floor. Advantageously, the vertical section, when used appropriately, provides a relatively large amount of space for routing the cables / conduits, while the cable duct itself protrudes less or not at all into the room. All the advantages and features of the cable duct segment according to the other aspects, the set of cable duct segments, the application, and the medical imaging system can be applied analogously to the cable duct segment according to this aspect, and vice versa.

[0028] Another aspect of the invention is a set of cable duct segments comprising at least one cable duct segment as described herein, in which the load-bearing layer is arranged further inwards 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 inwards and closer to the cable routing area than the load-bearing 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 for particularly good flexible length adjustment of a cable duct. In particular, the two cable duct segments can be assembled such that, in the area where the cable duct segments connect to one another, two load-bearing layers, namely one from each cable duct segment, are slid over each other.The different designs of the two cable duct segments allow for particularly easy assembly. Preferably, the load-bearing layers and the cuttable layers within a cable duct segment and between the two cable duct segments can be of the same thickness. The cuttable layer of each cable duct segment can be removed before assembly. A portion of the cuttable layer can remain, 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. Due to the different designs of the two variants, in one area the load-bearing layer is located on top, and in the other area the cuttable layer is located on top.Overall, this advantageously ensures that at least one load-bearing layer is present throughout the assembled cable duct. The set may include even more cable duct segments. In particular, it may be possible to flexibly assemble a cable duct from several cable duct segments. All cable duct segments may have a standardized, uniform length. The length is measured specifically in the direction of the cable routing. For example, the cable duct segments may each be 1 meter long, and a 1.7-meter-long straight section is to be provided. In this case, for instance, the cuttable layer of one of the cable duct segments could be scored from the inside 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 segment and then removed. The two cable duct segments can then be fitted together, creating a continuous, stable cable duct 1.7 meters long. Advantageously, this eliminates the need for a service technician to cut through the load-bearing layer. Therefore, a very stable, load-bearing (e.g., very hard) material can be used for the load-bearing layer, which does not require any on-site processing.

[0029] Particularly advantageously, the aspect of a cable duct segment with predetermined breaking points can be combined with an embodiment in which the cable guide is curved, preferably by an angle of 5° to 45°, more preferably 10° to 20°, and most preferably approximately 15°. The advantages and features described herein regarding the curved cable duct segment can also be provided analogously in this aspect. The combination of predetermined breaking points with the curved cable guide can be particularly advantageous because, in this combination, angles can be selected with great flexibility, depending on the required angle. For this purpose, it may suffice to simply separate the curved cable duct segment at the corresponding predetermined breaking point from a plurality of predetermined breaking points. This allows local requirements to be met particularly well.

[0030] 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 with predetermined breaking points can be provided for an end section of the cable duct. In particular, the cable duct segment can have a multitude of predetermined breaking points, thus enabling fine adjustment of the length. The main part of the cable duct, on the other hand, can 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, to be able to place curves at a desired location.

[0031] According to one embodiment, the set further comprises at least one cable duct segment whose cable path is curved, particularly as described herein. Advantageously, the set can thus also be used to create a cable duct which has one or more curved sections.

[0032] Another 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 (MRI) system. All the 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 an MRI system without a quench pipe, a particularly easy-to-install yet stable alternative for a cable conduit can thus be provided.

[0033] Another aspect of the invention is the use of a cable duct segment and / or a set of cable duct segments as described herein for the installation of a medical imaging system, in particular a magnetic resonance imaging system. All the 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 of the cable duct segment and vice versa.

[0034] All embodiments described herein can be combined with one another, unless explicitly stated otherwise.

Fig. Figure 7 shows a cross-section of a cable duct segment for guiding cables and / or wires along a cable routing path on a floor according to a further embodiment of the invention. Fig. Figure 8 shows a sectional view from the side of a cable duct segment, corresponding to the one shown in Fig. 7 is shown, Fig. Figure 9 shows a sectional view from the side of a cable duct segment according to a further embodiment of the invention, Fig. Figure 10 shows a top view of a cable duct segment according to a further embodiment of the invention and Fig. Figure 11 shows a medical imaging system with a cable duct that is assembled from cable duct segments according to an embodiment of the invention.

[0036] Fig. Figure 1 shows a cross-section of a cable duct segment 1 for guiding cables 10 and / or conductors 11 along a cable path on a floor according to an embodiment of the invention. The cable duct segment 1 comprises a cable guidance area 9 and a cover, arranged at least partially around the cable guidance area and extending along the cable path, for covering the guided cables 10 or conductors 11 from above. In this embodiment, the cover comprises a load-bearing layer 2, a cuttable layer 3, and an outer layer 4. The cuttable layer 3 and the load-bearing layer 2 are arranged further inwards and closer to the cable guidance area 9 than the outer layer 4. Furthermore, the cuttable layer 3 is arranged further inwards and closer to the cable guidance area 9 than the load-bearing layer 2. The load-bearing layer 2 is designed to bear the main part of the load and primarily to ensure the stability of the cable bridge.The cuttable layer 3 is less stable than the load-bearing 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, in the direction K of the cable routing path.

[0037] Fig. Figure 2 shows a cross-section of a cable duct segment 1 for guiding cables 10 and / or wires 10 along a cable routing path on a floor according to an embodiment of the invention. This embodiment corresponds to the one described in Figure 2. Fig. The embodiment shown in Figure 1 differs, however, in that the load-bearing layer 2 is arranged further inwards and closer to the cable guide area 9 than the cuttable layer 3. In other words, the arrangement of the load-bearing layer 2 and the cuttable layer is reversed. These two embodiments can therefore be combined particularly well to create a flexible cable duct, especially one with regard to length. The principle is explained in the Fig. 3 and Fig. 4 illustrates this.

[0038] Fig. Figure 3 shows a sectional side view of two cable duct segments 1, which may correspond to those found in Fig. 1 and Fig. Figure 2 is shown. For clarity, cables 10, lines 11, and partitions 5 are not shown here. The viewing direction corresponds to that shown in the Fig. 1 and Fig. As indicated in Figure 2, a portion of the cuttable layer has been removed. Preferably, the cable duct segments 1 have a standard length in the direction K of the cable routing. In this case, let's assume an exemplary length of 1 meter, and the goal is to create a composite piece 1.7 meters long from two cable duct segments 1, each one meter long. To achieve this, a 30 cm long section of the cuttable layer 3 is removed from each of the two cable duct segments. Additionally, 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 results in only the load-bearing layer 2 of the casing remaining in the area where the cuttable layer 3 was removed in the left cable duct segment 1, while in the right cable duct segment, the load-bearing layer 2 remains along with the outer layer 4.The two cable duct segments 1 are then pushed together, so that the situation changes from . Fig. This results in 4. The overall thickness of the casing is uniform throughout, and it is also ensured that the load-bearing layer 2 is present at least once along the entire cable routing path. Overall, a cable duct set to a desired length (1.7 meters in this example) can thus be provided relatively easily, especially without having to cut or otherwise process the (usually hard) load-bearing layer 2.

[0039] Fig. Figure 5 shows a cross-section of a cable duct segment 1 for guiding cables 10 and / or wires 11 along a cable path on a floor according to a further embodiment of the invention. The cable duct segment 1 comprises a cable guidance area 9 and a covering arranged at least partially around the cable guidance area and extending along the cable path for covering the guided cables 10 or wires 11 from above. In this embodiment, the covering comprises a load-bearing layer 2 and a cuttable layer 3 and may also include an outer layer 4. These layers are not explicitly shown here, but can be arranged accordingly as in Figure 5. Fig. 1 or Fig. The casing is arranged as shown in Figure 2. Viewed in the direction of the cable routing path, the casing comprises, in a central area, a flat cover section 21 and a base section 22, which runs essentially parallel to the cover section 21 and is designed to lie on the base 30 when the cable duct segment 1 is installed. Several partition walls 5 of the cable duct segment are also provided here, namely, in this case, two partition walls 5, which, viewed in the direction K of the cable routing path, extend perpendicularly from the cover section 21 to the base section 22. Furthermore, viewed in the direction K of the cable routing path, the casing includes a lateral ramp 23 in each of its two edge regions. The ramps 23 are inclined at an angle W of approximately 30° relative to the cover section 21.Furthermore, in this embodiment, the casing optionally includes a vertical section 24 at each of its outer edges, which extends substantially perpendicular to the cover section 21, with the lateral ramps 23 being arranged between the vertical section 24 and the respective cover section 21. The vertical section 24 is designed to be recessed into a base 30. This is shown in . Fig. Figure 6 illustrates this. A corresponding depression is worked into the ground 30, e.g. by milling.

[0040] Fig. Figure 7 shows a cross-section of a cable duct segment 1 for guiding cables 10 and / or wires 11 along a cable tray on a floor according to a further embodiment of the invention. A corresponding side view is shown in Figure 7. Fig. Figure 8 shows that the cable duct segment comprises a cable guidance area 9 and a covering, arranged at least partially around the cable guidance area and extending along the cable path, to cover the guided cables 10 or lines 11. The covering includes a load-bearing layer. As shown in Fig. As shown in Figure 8, the supporting layer 2 has several predetermined breaking points 41 designed to allow 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. 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 lie on the ground.

[0041] It is optionally possible to combine the variant with predetermined breaking points with the one with a cuttable layer 3, e.g. as shown in Fig. 1 and Fig. 2 shown. This is in Fig. Figure 9 illustrates where the cable duct segment has a load-bearing 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 layer can be cut off as needed, for example, with a knife. This has the advantage that no predetermined breaking points are visible on the outside. This prevents, for example, the ingress of liquids. It is also possible to provide for only the load-bearing layer 2 and the outer layer 4, or only the load-bearing layer 2 and the cuttable layer 3.

[0042] Optionally, the predetermined breaking points 41 can extend through the supporting layer 2 (or one or more further layers) in such a way that separating 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. Figure 10 indicates that a cable duct assembly is shown in a top view, with the course 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 the direction K of the cable routing.

[0043] 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 can, for example, correspond to those shown in the other figures.
