Description

[0001] Radiation protection housing

[0002] Description

[0003] Embodiments of the present invention relate to a radiation protection housing, in particular a radiation protection housing based on a modular construction kit concept.

[0004] Radiation protection housings for X-ray systems represent a market access barrier for new providers of X-ray inspection technology. The design of the required shielding, the proper construction of a housing, and its manufacture require a range of skills with a high degree of specialization. Even interrelated work steps such as designing the lead thickness and professional manufacturing are usually not available from a single source. Accordingly, the costs of implementing suitable housings are very high, and availability and delivery times are very limited. At the same time, the reliability of a radiation protection housing is of paramount importance, as the risk to life and limb posed by inadequate shielding is high. Therefore, its suitability must be reviewed by an independent expert every five years.This requires a robust system concept that has as few weak points as possible in terms of shielding and durability, otherwise the manufacturer would have to make costly improvements.

[0005] This means that current radiation protection enclosures are essentially custom-made, consisting of semi-finished products such as lead in the form of profiles, blanks, rolls, blocks, foil, or lead wool. One supplier of lead plates is Schneider. There are also companies that develop radiation protection enclosures specifically for customers, such as Ludwig Michl GmbH and Roehr + Stolberg.

[0006] The patent literature also contains several approaches to constructing a radiation protection shield. One example is disclosed in CN 108472005 B. US 5334847 A, EP 0220937 A2, WO 2009121907 A1, and EP 2501293 B1 also form the prior art. All approaches known from the patent literature have in common that they exhibit a high degree of specialization for corresponding applications. Furthermore, reference should be made to DIN 54113, which defines the basic principles for the construction of such housings. The object of the present invention is to create an improved compromise between radiation protection properties and flexibility.

[0007] The problem is solved by the subject matter of the independent patent claims.

[0008] Embodiments of the present invention provide a radiation protection housing based on the modular principle. The radiation protection housing comprises a base frame and a plurality of shielding panels which are fastened to the base frame by means of detachable fastening means. The base frame, shielding panels and detachable fastening means are part of a modular system. The base frame can, for example, be constructed analogously to the known panel profiles. According to embodiments, the shielding panels are designed to shield or absorb radiation, in particular X-radiation and in this case in particular X-radiation with, for example, 60 kV, 130 kV or 160 kV. According to further embodiments, the modular system comprises a plurality of shielding panels with, for example, different thicknesses, so that different shielding properties can be achieved orgenerally different shielding properties as well as different lateral dimensions. For example, a predetermined grid can exist within the kit, so that the different shielding panels are of different sizes. The base frame can also have different dimensions according to the same grid. As already mentioned above, a profile, such as an aluminum profile, is preferably used for the base frame, to which the shielding panels are attached. According to exemplary embodiments, a radiation protection profile or profile with a radiation protection element can be provided, in particular a radiation protection element arranged along a side surface of the profile and / or an end surface of the housing. Thus, the aluminum profile frame can advantageously be designed so that the corners and edges can also be realized without overlapping panels.

[0009] According to embodiments, the attachment is carried out using fastening means. These, according to embodiments, comprise a shielding collar. This means, viewed from the other side, that the modular system includes a shielding collar for the fastening means. Embodiments of the present invention are based on the finding that the modular construction of base frames (of different sizes) and shielding panels (of different shielding classes and / or sizes) in conjunction with detachable fastening means can create a modular system by means of which radiation protection housings can be easily manufactured. This results in the following advantages:

[0010] Design examples greatly simplify market access for new entrants in the X-ray market. Design examples offer significant savings potential by minimizing design and manufacturing costs by using easily manufactured mass-produced components. Furthermore, design examples close an important gap between a rapidly diversifying X-ray component market and the growing demand for integrated X-ray systems.

[0011] According to exemplary embodiments, all components, such as the shielding panels, fastening means, and the base frame, are designed to ensure sufficient shielding at the transition points corresponding to the desired shielding class. For this purpose, according to exemplary embodiments, the fastening means can be combined with a shielding collar, which, for example, has the shape of a washer or the shape of a cover for a screw head. Like the shielding panels, the shielding collar comprises a shielding material so that no radiation can escape. According to exemplary embodiments, the geometry of the shielding panels is also adapted so that they also prevent radiation from escaping at the transition points, e.g., at the edges.Such a modular system advantageously creates a scalable radiation protection housing that is suitable for different shielding classes depending on the selection of components from the kit. This makes the radiation protection housing more flexible, adaptable, and cost-effective, as a separate design of the individual housing is not necessary; instead, the components of the modular system are dimensioned and specified in their own right.

[0012] At this point, it should be noted that not only the shielding panels, as mentioned above, but also all other components of the modular system, such as the shielding collars, can have corresponding shielding properties. Depending on the exemplary embodiments, the shielding panels, shielding collars, and other components can be specified according to a specific shielding class. Differences can arise, for example, from the choice of material or the material thickness, so that components of the same type have different shielding characteristics, e.g., corresponding to the radiation protection class 60 kV, 130 kV, or 160 kV. Of course, other radiation protection classes are also conceivable. A fixed categorization can be used here. To facilitate application, the corresponding elements can be color-coded according to the categorization.

[0013] With regard to the shielding panels, it should be noted that, according to exemplary embodiments, these can have a sandwich construction, i.e., a central element, such as a lead element with enclosing metal sheets, is provided. According to exemplary embodiments, the shielding panels can have a different geometry. The geometry can differ, for example, in the number of folded edges, so that, for example, a first geometry has four folded edges, a second geometry two folded edges, and a third geometry no folded edge. This can create an overlap in the edge region, advantageously preventing radiation from escaping in the edge region. However, the overlap is limited to one layer in order to precisely define the installation height.Because the modular system includes a sheet with four folded edges, a sheet with two folded edges and a sheet without folded edges, the single-layer overlap is ensured not only in the edge area but also at the corners.

[0014] According to further embodiments, the modular system has screw plates for the outside so that elements can be attached to the outside of the radiation protection housing or the radiation protection housing can be connected to elements. A mounting point can also be provided for the inside. This is preferably arranged in the base frame. It is also conceivable that elements in the interior, such as an X-ray detector in the X-ray tube, can be connected to the housing. According to further embodiments, a screw plate can also be provided for mounting an element in the radiation protection housing or the radiation protection housing can be provided to an element on the outside, depending on how the screw plate is mounted. According to further embodiments, the screw plate replaces, for example, a shielding panel and therefore also has a shielding material, according to further embodiments.

[0015] According to further embodiments, additional attachments, such as a cable duct, a door, and a flap, can also be provided. These parts are preferably designed as penetrations of the radiation protection housing and can, for example, be provided at an opening in a shielding panel. According to embodiments, the attachments are mounted from the inside of the radiation protection housing into the shielding panel, with the attachments having a geometry such that an overlap with the shielding panel also exists here, thus preventing radiation leakage.

[0016] According to embodiments, the radiation protection housing is designed as a cubic shape, so that, for example, the shielding panels have a rectangular shape. According to embodiments, the radiation protection housing has a size of 0.5 to 5 m. 3 or between 0.8 and 1.5 m 3A typical size is 1 x 1 x 1 m 3 .

[0017] The following examples are explained using the attached drawings. They show:

[0024] Fig. 8 is a schematic representation of a profile for the frame with radiation protection element according to embodiments.

[0025] Before exemplary embodiments of the present invention are explained below with reference to the accompanying drawings, it should be noted that elements and structures with the same function are provided with the same reference numerals, so that the description of them is applicable to one another or interchangeable.

[0026] Fig. 1, 2, 3 represent the basic components of a radiation protection housing based on a modular kit concept. The idea of ​​the modular kit for the production of a radiation protection housing is that individual components, such as shielding panels, frames or frame components and fastening elements, are coordinated with one another in such a way that compatibility between them is ensured and, regardless of the combination of components, a clearly defined radiation protection property and dimensioning is achieved. All elements shown below, in particular the base frame shown in Fig. 1 and the shielding panels shown in Fig. 3, can be dimensioned in different sizes. A typical size is 1 x 1 x 1 m, so that a cubature of 1 m 3 The overall cubature can of course also be smaller, such as 0.25 m 3 or even larger, such as 5 m 3, The enclosed space is, for example, between 0.25 and 5 m 3 , preferably in the range between 0.8 and 1.5 m 3 The enclosed volume does not always have to be enclosed by a cube, but can also be enclosed by a cuboid. According to other embodiments, a shape other than a cuboid can also be created.

[0027] Fig. 1 shows a base frame 10 with, for example, the dimensions explained above. The base frame 10 has a cubic shape and thus forms six outer surfaces. The six outer surfaces are formed by 12 profiles extending along the edges of the cube. The 12 profiles are divided into four vertical profiles 12v, four horizontal profiles 12h, and four profiles 12d oriented in the depth direction. For example, the profiles can be aluminum profiles that are screwed together at the respective corners of the cube (aluminum frame on a profile base). In the embodiment shown here, 90° corners are always formed, so that the vertical profiles 12v, the horizontal profiles 12h, and the profiles 12d extending in the depth direction always have an identical length.In this embodiment, only the vertical profiles 12v differ in length from the other profiles 12h and 12d, which are approximately the same length. Approximately the same length because, due to the connecting geometry, a profile length difference prevails at the corners in order to form a rectangular side wall.

[0028] Fig. 3 then shows the shielding panels 22, 24 and 26 that can be screwed onto the profiles. The elements 22 are, for example, square and intended for the square side walls, while elements 24 and 26 are each rectangular and intended for the front or top and bottom. All shielding plates 22, 24 and 26 can differ from one another according to exemplary embodiments, e.g., in their geometry or bending geometry. The bend is provided with the reference numeral 22k or 24k. One of the elements, here element 22, has, for example, four folded sides 22k (all folded in one direction), while another element, here element 24, has two folded sides 24k (in one direction, namely the opposite direction), whereby element 26 has no folded side. So, for all six elements 22, 24 and 26, 12 folds are provided for the 12 edges of the cube.Of course, these folds can also be designed differently. For example, elements 24 and 26 could be identical, each with a fold. The purpose of the fold is to ensure an overlap, preventing a butt of the shielding plates. This overlap is replaced by overlaps to prevent radiation from passing through the joint area.

[0029] According to exemplary embodiments, the shielding panels 22, 24, and 26 can be screwed to the frame precisely in the area of ​​the bevel 22k, 24k, or 26k. For this purpose, through-holes are provided in this area. The through-holes are marked with the reference numeral 29. As can be clearly seen here, the through-hole extends once around the beveled area 22k or 24k and also through the flat area of ​​the respective adjacent shielding plate 24, 26, or 22. Screws for fastening the shielding plates 22, 24, 26 to the base frame can be provided in this area. The screws or general connecting elements are explained as examples in Figs. 2a and 2b. At this point, it should be noted that other screw connections for the modular system or other fastening elements, such as push-in rivets, can also be provided. According to preferred embodiments, the screws orthe screw connections or the connecting elements in general have shielding properties.

[0030] Fig. 2a shows a sectional view through the profile 12x, the shielding plate 22x and the screw 32 including the shielding sleeve 34. Fig. 2b shows a plan view, in particular of the screw 32 and the shielding sleeve 34.

[0031] Fig. 2a shows a screw 32 screwed into a nut 34. The nut 34 is a nut of profile 12x inserted into the profile groove (compare with the previously mentioned profiles 12v, 12h, and 12d). The nut 34 is inserted into a groove of profile 12x so that something can be attached to the profile using the screw 32. In this exemplary embodiment, the shielding plate 22x (compare with the shielding plates 22, 24, and 26) is screwed on. To prevent radiation, which is represented here by the arrows, from escaping through the through-hole, a shielding collar 34 is provided in the area of ​​the screw head 32k. This shielding collar 34 is also shown in Fig. 2b, namely in a top view. The shielding collar 34 can, for example, be slipped onto the screw head 32k. Alternatively, it would also be conceivable that the shielding sleeve 34 is screwed on. This situation is shown here.The shielding collar 34 is placed on top of the screw head 32k and fastened by means of screws 34s to a washer 34u, which is inserted beneath the screw head 32k. Alternatively, the shielding collar 34 can, of course, also be implemented as a type of washer. Now that its functionality has been explained, the effect and manufacturing method of the shielding collar 34 will be discussed below. The shielding collar is attached over the protruding screw head of a screw guided through the housing by locking it onto a screwing device, either as a washer or on the screw head of the through-bolt, above the through-bolt. Security screws are used for this purpose, which prevent easy unscrewing and thus comply with safety regulations. The shielding collar's shielding thickness is designed for the respective protection category (A, B, C) and is color-coded.The shielding collar can be made of lead, either by casting or from a special plastic injection molding process. The washer thus complements the actual connecting screw, which has screwing surfaces that, in turn, serve to screw on the radiation protection cover. In addition to the shielding itself, this also allows for tightening with safety screws, which is another important feature for such enclosures.

[0032] Optional aspects of the radiation protection housing and in particular of the shielding panels 22, 24 and 26 are explained below. The housings 10, for example, have a rectangular structure consisting of six end faces. The panels 22, 24 and 26 are offered in a fixed size grid and have three types of design which together create the overlap areas for radiation shielding. The basic material for the surface shielding is a lead element of the appropriate thickness (A, B, C) clad on both sides with metal sheet. This is shaped differently for the three different panel categories i. Type 1: End faces - The end faces of the panel 22 are covered by a sheet-lead-sheet panel pressed on four sides. The pressing process ensures that the corners of the housing are sufficiently covered without causing any radiation leakage. ii.Type 2: Side surfaces 1: The side surfaces of panel 24 are, on the one hand, smooth and without edges. iii. Type 3: Side surface 2: Two additional side surfaces of panel 26 are each designed with an edge on the short sides.

[0033] An alternative to the overlap is explained below with reference to Fig. 8.

[0034] Fig. 8 shows a profile / square profile / aluminum profile for the base frame in a sectional view. As can be seen, the profile 12 can have a plurality of recesses 63, here four recesses 63 on the respective side surfaces. The recesses 63 serve to accommodate a nut / groove nut into which the connecting means / connecting screws 32 explained above can be screwed. In addition, additional recesses 65 can also be provided, e.g. on the edges of the profile 12. According to one embodiment, it would be conceivable for optional radiation protection elements 67 to be inserted into one of the profiles 63 or 65, here into the profile 65 or even into several profiles. For example, the element 67 can be a lead insert along an end face of the profile 12. The element or the slat 67 can also have a profile shape.The slat 67 can prevent radiation from escaping through the edge joint of panels 22, 24, and 26 even without folding. According to the exemplary embodiments, the panels 22, 24, and 26 have an overlap 22ü in the edge area. This serves as additional radiation protection.

[0035] Depending on the design examples, add-on components can be included in the kit. These include, for example, cable glands and hatch doors. Cable glands, doors, and hatches are offered as standard assemblies that are screwed directly onto the shielding panels. The necessary openings and screw points are pre-cut on the panels 22x, for example. The add-on components are screwed through from the inside to the outside (see screw 32) and sealed using the shielding sleeves 34.

[0036] Fig. 4 shows the attachment of a flap 40 to a shielding element 22x using a screw 32. The screw 32 is screwed through the shielding profile 22x from the inside and engages in a thread of a component of the flap 40. In this exemplary embodiment, the screw 32 also has a shielding sleeve 34. For example, the cover 40 is located on the inside, while the cover is screwed tight from the inside using the screw 32. According to further exemplary embodiments, this can also be the other way around, for example if the cover 40 is intended to open outwards. According to exemplary embodiments, the cover 40 itself has a shielding material, in particular if it is intended to cover a passage, such as a cable duct or an opening.

[0037] Another attachment is shown in Figs. 5a and 5b, namely a mounting point 50. Fig. 5a shows a cross-sectional view of the mounting point 50, while Fig. 5b shows a top view of the mounting point. The mounting point is used for mounting internal components, such as X-ray components and positioning devices, or for connecting the radiation protection housing to or with an external component.

[0038] The element can, for example, be coupled to the profile 12x, as shown in Fig. 6a and 6b. The mounting point 50 comprises, for example, four fastening screws for fastening the mounting point 50 to the profile 10x. For this purpose, the screws 58 shown in Fig. 6 can be used, for example. Furthermore, the mounting point 50 comprises a recess 52 for the screw 32 with or without a shielding sleeve 34. The screw 32 protrudes through the mounting point 50 from a first side, while the screws 58 protrude through the mounting point 50 from a second (opposite) side. In addition, the mounting point can also have recesses 54 for shielding elements 54a, which are less relevant for use inside the radiation protection housing (Fig. 6a) but more relevant on the outside (Fig. 6b).

[0039] As shown in Fig. 6a, an element 55 can be mounted to the frame 12x, e.g., on the inside, by means of the mounting point 50. The element 55 is, for example, a component of the X-ray system, such as a radiation receiver, which is connected to the screw 32. Instead of the screw, a nut can also be inserted into the recess 52 so that the component to be fastened can also be fastened directly with a screw. The recess 52 can also have the shape of a nut (hexagon) or a screw head to facilitate the screwing-in process by providing torque support. Element 50 can also have a thread instead.

[0040] Fig. 7 illustrates the attachment of the mounting points 57 to the elements 12v, 12h, and 12d by means of the screws 58. In this respect, the screw plate 50 can form a mounting point 57 on the inside.

[0041] In addition to the mounting points for larger elements, smaller elements, such as safety elements such as door contact switches and lighting systems, can be attached as additional add-on components using preconfigured adapters.

[0042] According to exemplary embodiments, the mounting point 50 serves not only for mounting elements on the inside of the housing 10, but also on the outside. This example is explained below based on Fig. 6b.

[0043] Fig. 6b illustrates the use of element 50 on the outside. Fig. 6b shows a profile 12x, onto which a shielding plate 22x is mounted using fasteners 32 and 32k. The fasteners 32 not only secure the shielding plate 22x to the profile 12x, but also the mounting plate 50.

[0044] In this exemplary embodiment, the element 50 is not mounted from the inside by means of screws 58, but rather fastens the entire system to another element, such as another profile 13, via the outside. The radiation protection housing can then be screwed to an external element (another profile 13) or an external element can be screwed to the radiation protection housing. To prevent radiation from escaping, further radiation absorbers 54a are provided in the recesses 54. These elements 54a could also be referred to as radiation protection reveals. Radiation absorbers 54a and recesses 54 can, for example, be arranged concentrically around the screw 32. The screw 32 with screw head 32k and shielding sleeve 34 are arranged in the recess 52 from the other side.

[0045] In summary, it can be stated that the modular system can have a mounting point for attaching components on the inside as well as add-on parts on the outside.

[0046] The modular kit for creating a radiation protection housing thus essentially forms the radiation protection housing itself based on a profile frame in combination with shielding plates that are connected to the base housing using detachable fastening elements, such as screws. Furthermore, the modular kit can also include additional add-on components, such as covers, cable ducts, or flaps. Additionally or alternatively, the modular radiation protection kit can also include mounting points for attaching X-ray components inside or other components in the outer component. Preferably, all fastening components are connected to the base frame. Add-on components can also be connected to the shielding panels, depending on the embodiment.

[0047] All penetrations of the shielding panels, such as screw holes, can be equipped with additional radiation protection devices, such as shielding collars, depending on the design. Additional radiation protection reveals can also be provided.

[0048] All shielding elements, such as the shielding panels, can be available in different shielding classes in a modular system. This means that several different shielding panels are provided for one size, which differ, for example, in terms of their shielding characteristics, particularly their thickness. The shielding collars can also be of different dimensions. Preferably, a shielding material or a shielding sandwich structure is used to prevent damage to the shielding material. It should be noted here that the shielding panels can also vary in other ways, namely in terms of their geometric dimensions (length, width), so that radiation protection devices of different sizes can be created with the same modular system. The size of the profiles also varies according to the size of the shielding panels (see 12v, 12h, and 12d).This makes it advantageously possible to create radiation protection housings of different sizes (cubic).

[0049] A further embodiment provides a radiation protection housing, in particular a cubic radiation protection housing, e.g., for security checks, industrial X-ray systems, or X-ray systems in medical technology, with a radiation source and / or X-ray detector arranged in the radiation protection housing. The radiation protection housing or the radiation protection housing can be designed for X-rays or other radiation.

[0050] Even though the above embodiments always referred to a cubic radiation protection housing, it would also be conceivable that instead of the cubic housing with six side surfaces, a radiation protection housing with more than six, such as eight or ten side surfaces, could be created.

[0051] The above embodiments are only illustrative, the scope of the invention being defined by the following claims.
