In addition, the computing unit of the medical imaging device or the computing unit can also be designed to control the medical imaging device during the generation of image data, for example, to generate control instructions for an X-ray source and / or an X-ray detector.

[0009] In other words, in an embodiment of the present invention, the medical imaging facility includes one or more, for example, two or more, computing units, and the computing units are respectively arranged or housed in a computer housing according to the present invention.

[0010] The computing unit is typically designed to include at least one, preferably a plurality of, computing modules or data processing units or computers. A computing module corresponds, for example, to a central processing unit (CPU) or a graphics processing unit (GPU).

[0011] According to the present invention, the computing unit of the medical imaging facility or the computing unit is directly arranged at or in the unit for generating image data of the medical imaging facility in the examination room, such as a gantry, remotely arranged in an adjacent control room and / or separately arranged from the unit for generating image data.

[0012] The computer housing of a medical imaging device has a basic rectangular parallelepiped shape and is made of a metal material. According to the utility model, the computer housing is formed by a plurality of outer surfaces or outer walls. The outer surfaces are connected to other outer surfaces at their edges, thereby enclosing an inner space. The computer housing is used to accommodate a computing unit in its interior. In particular, according to the utility model, the outer surface of the computer housing is made of a particularly corrosion-resistant and stable galvanized steel sheet. Instead of the galvanized steel sheet, other components of the computer housing according to the utility model can also be made of aluminum as an alternative, and the other components are introduced in more detail below.

[0013] The outside of the computer housing includes two opposite side surfaces, a front and an opposite rear surface, and a bottom surface and a top surface arranged oppositely. The side surfaces and the front and rear surface preferably have a height of 150 mm to 200 mm. According to the utility model, the width of the front and rear surface is preferably between 400 mm and 500 mm. The side surfaces preferably have a width of 450 mm to 550 mm. In a particularly preferred embodiment, the computer housing has the following dimensions: height: 176 mm, width: 450 mm, and depth: 502 mm. According to the utility model, the thickness or material strength of the outside surface is between 0.9 mm and 1.1 mm, preferably 1 mm.

[0014] The side surfaces can be designed for installing or fastening the computer housing in or on a supporting component of the medical imaging system, while the front and rear of the computer housing primarily provide interfaces for operating, contacting, supplying energy and / or cooling the computing unit.

[0015] The front side may include, for example, a plug socket for connecting a power supply cable, an external data storage device or a data line. The front side may also include an operating switch for the computing unit, for example in the form of a switch button or the like. In addition, ventilation grilles or ventilation slots may be provided in the front and / or rear side of the computer housing, through which cooling air may be introduced into the interior of the computer housing during operation of the computing unit, and exhaust air may be led out of the computer housing again. In other embodiments of the utility model, the rear side of the computer housing may also include such an interface.

[0016] Correspondingly, in addition to the computing unit, a cooling unit may also be provided in the interior of the computer housing, for example in the form of a defined flow path which guides cooling air through individual computing modules or individual computing modules.

[0017] In addition, in the embodiment of the present utility model, the computing unit of the medical imaging facility or the computing unit has an interface unit, which has one or more operating interfaces and / or multiple data interfaces for data communication, which can be touched via the interface in the front, for example. The interface unit also arranged in the computer housing or at the computer housing is used, for example, to exchange images or control data with the imaging unit of the medical imaging facility. The interface unit is also used to exchange information between the operator of the medical imaging facility and the computing unit. For example, the status information of the computing unit can be displayed to the operator via the output unit, and the control instructions can be input via the input unit. The interface unit can also be configured to exchange data between the computing unit of the medical imaging facility and other components or hospital information systems (HIS) or radiology information systems (RIS). The interface unit can also be configured to exchange data between the various computing modules of the computing unit. Each data interface can be implemented in the form of a hardware and / or software interface, such as a PCI bus, a USB interface, a FireWire interface, a ZigBee or a Bluetooth interface. The interface unit can also have an interface of a communication network, wherein the communication network can be a local area network (LAN), such as an intranet or a wide area network (WAN). Correspondingly, the interface unit may have a LAN interface or a wireless LAN interface (WLAN or Wi-Fi).

[0018] Now, the computer housing according to the utility model is characterized in that an operating interface for operating the computing unit or a ventilation element for cooling the computing unit is respectively included in the front and the rear. Here, the operating interface and the ventilation element are respectively arranged in the front or the rear so as to be interchangeable with each other. That is, the operating interface and the ventilation element as well as the front and the rear are configured so that the position of the operating interface and the ventilation element between the front and the rear is easily feasible, that is, it is feasible in particular without other structural adjustments to the computer housing.

[0019] The inventors of the utility model have recognized that, in this way, for different operating or installation positions of the computer housing relative to the medical imaging device, a simple adjustment of the layout of the user interface can be achieved while maintaining a high degree of component identity.

[0020] In a preferred embodiment of the present invention, the adjustment or exchange of the settings of the operating interface and the ventilation element is achieved in the following manner: the operating interface and the ventilation element are respectively integrated in the surface segment. The surface segment has the same external shape here and is detachably connected to the front and / or back. The surface segment is preferably also made of galvanized steel sheet with the same material thickness. Through the same external shape, during installation, the surface segments can be arbitrarily exchanged with each other or arranged and fixed at any position without adjustment in the front or back / front or back. The surface segment preferably has an edge size between 92mm and 98mm, that is, for example, it can be 96.4mm wide and 94.4mm high. The surface segment is also preferably composed of a galvanized steel sheet with a material thickness of 1mm.

[0021] According to the invention, in a preferred embodiment of the computer housing, recesses are provided in the front and back sides according to the shape and size of the surface segments, wherein the surface segments can be inserted into one of the recesses respectively. In the case of good fit accuracy for the surface segments, the recesses preferably have a size between 91.8 mm and 98.2 mm, preferably a width of 96.5 mm and a height of 94.5 mm.

[0022] In order to facilitate the insertion of the surface segment into one of the recesses, both the surface segment and the recess can have a frame, which is preferably also made of galvanized steel sheet, extends closed around the recess or the surface segment and perpendicular to the front or rear side or the surface segment, respectively. The vertical extension of the frame can extend from 3 mm to 40 mm, for example 30 mm or 35 mm. In this way, the surface segment also provides sufficient depth for integrating an operator interface or a ventilation element.

[0023] Thus, the surface segment can be pushed into the recess, in particular the frame of the recess. In order to ensure a stable and secure fixation of the surface segment in the recess, each surface segment can preferably be fixed in the recess by means of two connecting elements. The two connecting elements are preferably designed as screw connections, wherein the screws are guided through holes in the surface segment and screwed into threaded holes in the front or back side with precise position. The holes in the surface segment can be arranged in the surface projection so that the screws extend perpendicularly to the surface segment plane in the installed state.

[0024] Likewise, alternative arrangements for screwing holes in the front or back side or in the surface section are conceivable. As an alternative to a connecting element comprising a screw, an alternative connecting element can be provided, for example a locking connection, a clamping connection or a clip connection, wherein a spring element arranged at the surface section is guided through a locking opening in the front or back side and in the fully inserted state at least partially engages the locking opening at the back due to the spring effect, thus also fixing the surface section precisely in position. Other alternatives are conceivable here. Likewise, the number of connecting elements can be varied as desired, in particular the number of connecting elements can be increased, for example in order to achieve a more stable connection.

[0025] In an embodiment of the present invention, the operation interface is at least one operation interface from the group consisting of: an operation switch of a computing unit, a data interface, and an output unit for displaying the status of the computing unit. The operation switch is used to put the computing unit into operation or shut down the computing unit. In a preferred embodiment, the data interface is preferably configured as a USB slot or an SD card slot. In a preferred embodiment, the output unit is configured as a panel including one to three LED lights.

[0026] In a particularly preferred embodiment of the present invention, the operation interface has an operation switch, a USB slot, an SD card slot and an LED panel.

[0027] As already mentioned above, the computing unit is cooled during operation. For this purpose, the computer housing according to the invention comprises ventilation slots or ventilation openings in order to enable cooling air exchange. The ventilation element arranged in the surface section plays an active role in this. The ventilation element comprises a rotatably mounted impeller, which can be rotated by means of a drive to generate a cooling air flow. In other words, the ventilation element is designed to actively convey cooling air into the computer housing or out of the computer housing depending on the installation position.

[0028] In this case, the impeller has a first direction of rotation when the ventilation element is arranged in the front side, and the impeller has a second direction of rotation opposite to the first direction of rotation when the ventilation module is arranged in the rear side.

[0029] In other words, according to the invention, in the sense of a computer housing kit, two versions of the surface section including the ventilation element are provided, which can be selected depending on the desired installation position. The installation position of the ventilation element depends on the operating position of the computer housing. According to the invention, a vertical, ie vertical, operating position and a horizontal operating position are distinguished for the computer housing.

[0030] For a vertical operating position of the computer housing, such as a computer tower, according to a preferred embodiment, the surface section containing the user interface is arranged in the front and the surface section containing the ventilation element is arranged in the rear. In the vertical operating position, one of the side faces is oriented downward, i.e., toward the base of the medical imaging device. The computer housing essentially stands upright on these side faces. In the vertical operating position, the user interface is arranged in the front at the front and is accessible to the operator from the front.

[0031] In the horizontal operating position, the computer housing stands upright or lies flat on the bottom surface. In other words, in the horizontal operating position, the bottom surface is oriented downward. In the horizontal operating position, the surface section including the user interface is arranged in the back, and the surface section including the ventilation element is arranged in the front.

[0032] In addition to the recess for one of the surface segments, further ventilation elements are also provided or integrated in the front face, which can be designed as described above. In particular, three further ventilation elements can be provided. The ventilation elements act together in the case of effective cooling of the computing unit and have the same direction of rotation.

[0033] In the horizontal operating position, the direction of rotation of the ventilation element integrated in the surface section in the front is implemented so that the impeller conveys cooling air from the outside to the inside of the computer housing. Other ventilation elements arranged in the front also convey cooling air from the outside through the front to the inside.

[0034] In this embodiment, only one ventilation grille is provided in the rear side of the computer housing, which allows cooling air to flow passively out of the computer housing.

[0035] In a preferred embodiment, in the vertical operating position, in addition to the surface section including the user interface, three further ventilation elements with the same direction of rotation are also provided in the front of the computer housing in order to convey cooling air into the interior of the computer housing. Ventilation elements with the opposite direction of rotation are integrated in the surface section integrated in the rear side. In this embodiment, the ventilation elements are used to actively convey exhaust air from the interior of the computer housing to the outside.

[0036] In the sense of a high degree of component identity, three further ventilation elements in the front face are preferably also integrated in the surface segment designed according to the invention and are accommodated in corresponding recesses in the front face, as described above.

[0037] In other embodiments of the computer housing with a vertical operating posture, two bases are also included, on which the computer housing can be stably set up. The base is preferably connected to the lower side of the downwardly oriented side. The base is preferably made of aluminum. In an embodiment, in order to achieve particularly high stability, the base has a width that is greater than the height of the side.

[0038] In the implementation scheme, for the case where the operating interface of the computing unit does not need to be touched in the vertical operating posture, a front cover is provided for covering the front and for filtering the cooling air. The front cover is arranged directly in front of the front in the closed state, but can be opened like a cover or door when necessary, for example, by means of two hinges. The size of the front cover basically corresponds to the size of the front and back. The front cover can also be made of galvanized steel sheet. According to the utility model, in addition to protecting the front, the front cover is also used to filter the cooling air. For the purpose, the front cover includes a plurality of inlet openings, each of which is coated with a filter material. The filter material is mainly used for physical filtering of the air, that is, to remove dirt particles or dust, etc. Correspondingly, in the implementation scheme of the utility model, the filter material can be configured as PUR foam (PUR = polyurethane). The PUR foam can be fastened to the inner side of the front cover in the form of a pad and cover all inlet openings.

[0039] In other embodiments, two holding handles can be provided on the sides of the computer housing for the horizontal operating position. The holding handles can be screwed directly into the edge region with the side faces pointing in the front and rear directions, for example, by means of metal angles. The holding handles facilitate the insertion and removal of the computer housing into, for example, a switch cabinet of a medical imaging facility.

[0040] The computer housing according to the invention is characterized by a high degree of component identity, regardless of the configuration of the computing unit in the interior of the computer housing. All exterior surfaces of the computer housing, in particular also the front and back surfaces, can be made of identical components, so that warehouse management can be made more efficient and the expansion effect takes effect during material purchase and manufacturing. Only in order to be able to realize different operating postures of the computer housing, different variants of the surface segment including the ventilation element are provided, the rotation direction of the ventilation element being preset according to the installation position of the surface segment preset by the operating posture. However, the other structures of the computer housing advantageously remain unchanged. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 1 A view of a computer housing CG according to the present invention in one embodiment of the present invention is shown. The computer housing CG constitutes a computing unit (not shown) for accommodating a medical imaging device (not shown). At present, the computer housing CG shows a basic shape of a cuboid with three differently configured side lengths. Side ratios different from those shown are also conceivable. The computer housing CG is composed of six outer surfaces that simulate the shape of a cuboid, namely two side surfaces SF, a bottom surface GF, a top surface DF (see Figure 4and below), a front face FF and a rear face RF. The bottom face GF and the top face DF form essentially closed surfaces, while the front face FF and the rear face RF are provided with openings or interfaces as described with reference to the rear face RF and at least partially with reference to the front face FF. Thus, in the embodiment described, the rear face RF comprises different data interfaces DS (see also Figure 8 ), power supply interface VS and / or ventilation grille LG for inputting or outputting cooling air. Alternatively or additionally, a single or all of the openings or interfaces described in the above FF may also be provided.

[0051] The outer surfaces are connected to each other at or near their edges, thereby separating the enclosed interior space from the environment. A computing unit can be placed in the interior space thus formed, and the computing unit includes at least one computing module, such as a CPU or a GPU. According to the utility model, the outer surface of the computer housing CG is made of a metal material. Currently, the material is made of a particularly corrosion-resistant and stable galvanized steel sheet.

[0052] The rear side RF comprises a recess AN, of which four recesses AN are arranged in a row in the front side FF. The recesses AN are each used to accommodate a surface segment FS, which is referred to as Figure 2 and Figure 3 In more detail. In the present embodiment, all recesses AN have a first edge R1 extending perpendicularly to the front face FF or the rear face RF. The first edge R1 is inserted precisely into each recess AN or is otherwise connected to each recess. The first edge R1 serves, on the one hand, to position the surface segment FS more stably in the recess AN. For example, a locking element can be integrated in the first edge R1, which acts together with the surface segment FS and, in addition to other connecting elements VE (see Figure 2 and Figure 3 ), the locking element secures the surface segment FS circumferentially in place. In addition, the first edge R1 also comprises a plurality of spring plates FB, which, after the surface segment FS has been pushed into the recess AN, rest against the surface segment FS (see Figure 2 and Figure 3 ) at the second edge R2 of the computer housing CG and is used for EMC shielding. EMC shielding (EMC = electromagnetic compatibility) is used to limit the propagation of electromagnetic radiation or electromagnetic fields generated by electrical components in the computer housing CG, such as a computing unit or individual computing modules. By providing an EMC protection element in the computer housing CG, other electrical components in the surrounding area as well as patients and medical personnel can be advantageously protected.

[0053] All recesses AN of the computer housing CG are identically configured, in particular, they have the same edge dimensions, i.e., they are all the same size. In this regard, the recesses AN allow different surface sections FS, which are also characterized by the same dimensions, to be installed at different locations in the computer housing CG according to the invention.

[0054] Figure 2 A detailed view of a surface section FS including a user interface BSS in one exemplary embodiment of the invention is now shown.

[0055] Figure 3 A detailed view of a surface section FS comprising a ventilation element LE is shown, likewise in one embodiment of the invention.

[0056] The user interface BSS is used to operate the computing unit, while the ventilation element LE is used to cool the computing unit. By selecting the arrangement of the user interface BSS and the ventilation element LE in each surface segment FS, the user interface BSS and the ventilation element LE can be interchangeably arranged in the front and rear surfaces FF, RF. That is, the position of the user interface BSS can be selected during the installation of the computer housing CG while taking into account the operating posture of the computer housing CG.

[0057] As already indicated above, the surface segments FS have the same outer shape, and in particular they have the same dimensions. The dimensions of the surface segments FS are matched to the dimensions of the recess AN with regard to optimized fit accuracy. The surface segment FS is hereby detachably connected to the front and / or rear sides FF, RF. For this purpose, a surface protrusion is currently provided on the surface segment FS: the surface protrusion protrudes from the recess AN and can be fixed to the front or rear side FF, RF by means of a connecting element VE in the form of a screw. In order to stably support the surface segment FS in the recess AN, the surface segment FS comprises a second edge R2, which is adjacent to the first edge R1 and is substantially flush with the first edge R1 when the surface segment FS is pushed into the recess. In addition to its positive contribution to the EMC shielding, the second edge also realizes the necessary structural depth of the surface segment FS in order to integrate the operator interface BSS or the ventilation element LE.

[0058] according to Figure 2 The operating interface BSS is formed with an equal number of operating elements, including an operating switch BS and a reset switch RS for the computing unit, two data interfaces DS in the form of a USB port and an SD card slot, and an output unit LP in the form of an LED status panel.

[0059] according to Figure 3The ventilation element LE integrated into the surface section FS comprises a rotatably mounted impeller FL which is arranged behind a ventilation grille LG. The impeller is rotatably designed by means of a drive in order to generate a cooling air flow.

[0060] According to the invention, a ventilation element LE can be provided in two variants. Here, according to a first variant, when the ventilation element LE is arranged in the front face FF, the impeller FL has a first rotation direction, and when the ventilation element LE is arranged in the back face RF, the impeller FL has a second rotation direction opposite to the first rotation direction.

[0061] Whether a surface section including the ventilation element LE must be provided in the front side FF or in the rear side RF depends on the operating attitude or installation position of the computer housing CG relative to the medical imaging device.

[0062] The vertical operating position VBL describes a position in which the computer housing CG is arranged vertically on one of its sides SF. This also refers to the use of the computer housing CG in the form of a tower or stand computer.

[0063] The horizontal operating position HBL describes a position in which the computer housing CG lies horizontally on the bottom surface GF and is installed, for example, in a switch cabinet of a medical imaging system.

[0064] Figure 4 1 shows a perspective view of a computer housing CG according to the invention in a vertical operating position VBL, more precisely with a closed front cover FK in one embodiment of the invention.

[0065] Figure 5 Show Figure 4 Another perspective view of the computer housing CG shown in FIG. 1 , but here the computer housing CG does not have a front cover FK.

[0066] Figure 6 Show Figure 4 A three-dimensional rear view of the computer housing CG shown in FIG.

[0067] In the vertical operating position VBL, the computer housing CG comprises two bases ST made of aluminum, which are fastened to the lower side SF near the front FF and the rear RF. The bases serve to stabilize the computer housing CG in an upright position. For this purpose, the bases ST protrude laterally beyond the side height.

[0068] In the vertical operating position VBL, the surface segment FS including the user interface BSS is arranged in the front side FF, and the surface segment FS including the ventilation element LE is arranged in the rear side RF.

[0069] In addition, the computer housing CG in the embodiment also includes the front cover FK, which is used to cover the front face FF and filter the cooling air. Figure 4 As shown in the figure, the front cover FK is arranged directly in front of the front face FF and covers and protects the front face FF without the need to enter the user interface BSS or to have visual contact with the user interface BSS. As the name already indicates, the front cover FK can be opened and releases the front face FF or the user interface BSS in the opened state. In this way, in the embodiment, the user interface is arranged to be easily accessible to the user.

[0070] In addition to the operator interface BSS, in the embodiment, three further ventilation elements LE are integrated in the front face FF. The ventilation elements are also inserted into the recess AN provided for this purpose in the surface section FS according to the invention. The directions of rotation of the impellers FR of the three ventilation elements LE are the same and allow cooling air to be sucked from the outside into the interior of the computer housing CG.

[0071] The ventilation element LE arranged in the surface section FS in the rear side RF comprises an impeller FR, which rotates in the opposite direction. The ventilation element LE thus serves to remove hot exhaust air from the computer housing CG via the rear side RF. In order to further facilitate the removal of exhaust air from the computer housing CG, a further passive ventilation grille LG is arranged in the rear side RF, which allows air circulation between the interior of the computer housing and the environment.

[0072] In order to ensure adequate cooling performance even in the closed state of the front cover FK, the front cover FK comprises a plurality of air inlets or ventilation openings. Cooling air can enter through these air inlets or ventilation openings. Ventilation openings The filter material FM is formed in the form of a single PUR foam pad, which covers all ventilation openings at the same time. The PUR foam can block dirt particles such as dust contained in the inflowing cooling air.

[0073] In an embodiment, a painted cover plate (not shown) can be provided for the vertical operating position VBL, which can be placed on the upper of the two side surfaces SF as an external, visually appealing closure. The cover plate has essentially the dimensions of the side surfaces SF, but is preferably made of aluminum. If the front cover FK is closed, the cover plate is preferably flush with the front cover FK at its side edges. The front cover FK, like the side surfaces SF, can also be designed to be painted at least on its outer side like the cover plate.

[0074] Figure 7 A perspective front view of a computer housing CG according to the invention is shown in one embodiment of the invention in a horizontal operating position HBL with an installed surface section FS.

[0075] Figure 8 Show Figure 7 A three-dimensional rear view of the computer housing CG shown in FIG.

[0076] In the horizontal operating position HBL, the computer housing CG lies essentially flat on the bottom surface GF. This position is preferred, for example, when the computer housing CG is integrated into a switch rack or control cabinet of a medical imaging facility. In the horizontal operating position HBL of the computer housing CG, the surface section FS including the operator interface BSS is arranged in the back side RF of the computer housing CG, and the surface section FS including the ventilation element LE is arranged in the front side FF of the computer housing CG.

[0077] In the embodiment, as in Figure 7 As can be seen in the front FF, four identical ventilation elements LE are provided, the impellers FR of which all have the same direction of rotation and which are all used to draw cooling air from the environment. In the embodiment described, the exhaust air is discharged exclusively via the ventilation grille LG, which is also included in the rear RF.

[0078] In order to facilitate the operation and installation of the computer housing CG according to the present invention in the switch cabinet, the computer housing CG includes two holding handles HG at the side SF. The holding handles are respectively installed twice on almost each side SF by means of angle pieces, that is, once on the side edge relative to the front FF, and once on the side edge relative to the back RF. In this way, the computer housing CG can be inserted into or removed from the switch cabinet not only from the rear but also from the front.

[0079] Although the details of the present invention have been described in detail through preferred embodiments, the present invention is not limited to the embodiments, and those skilled in the art can derive other variations therefrom without departing from the protection scope of the present invention.
