Abstract
Description
[0001] The invention relates to an arrangement comprising a tablet computer unit with a tablet computer and a housing part of a medical imaging device.
[0002] A medical imaging device can be operated, in particular, using a tablet computer. During a medical examination conducted using the medical imaging device, it can be advantageous if the tablet computer can be attached to a housing part of the medical imaging device for certain examination steps and used independently of the housing part for other examination steps. Furthermore, it is advantageous if the tablet computer can be charged with electrical energy without contact while attached to the housing part. The housing part of the medical imaging device can be, for example, a housing part of a gantry of the medical imaging device or a housing part of a docking station of the medical imaging device.
[0003] The invention aims to enable an improved arrangement of a tablet computer unit on a housing part of a medical imaging device.
[0004] The subject matter of the independent claim solves this problem. Further advantageous aspects of the invention are considered in the dependent claims.
[0005] The invention relates to an arrangement comprising - a tablet computer unit comprising a tablet computer and a first connection unit having a set of ferromagnetic regions, - a housing part of a medical imaging device, wherein the housing part of the medical imaging device has a cover and a second connection unit, - wherein the casing has a recess into which the tablet computer unit can be positively received, - wherein the second connecting unit is arranged in a region of the recess such that a magnetic connection can be formed by means of the first connecting unit and the second connecting unit, which counteracts removal of the tablet computer unit from the recess.
[0006] It is planned - that the second connecting unit has a first set of magnetic regions which are spaced apart from one another and each face the recess with its north pole and which together generate a first magnetic flux, - that the second connecting unit has a second set of magnetic regions which are spaced apart from one another and each face the recess with its south pole and which together generate a second magnetic flux, and - that an absolute value of the first magnetic flux through the cladding in the region of the recess is substantially equal to an absolute value of the second magnetic flux through the cladding in the region of the recess.
[0007] In the context of this disclosure, the absolute amount of the first magnetic flux through the cladding in the region of the depression is considered to be substantially equal to the absolute amount of the second magnetic flux through the cladding in the region of the depression, in particular when the absolute amount of the first magnetic flux through the cladding in the region of the depression is greater than 80 percent, for example greater than 90 percent, preferably greater than 95 percent, and less than 120 percent, for example less than 110 percent, preferably less than 105 percent, of the absolute amount of the second magnetic flux through the cladding in the region of the depression.
[0008] In particular, the absolute value of the first magnetic flux through the cladding in the region of the recess is then substantially equal to the absolute value of the second magnetic flux through the cladding in the region of the recess when the absolute value of the first magnetic flux through the cladding in the region of the recess is equal to the absolute value of the second magnetic flux through the cladding in the region of the recess.
[0009] In particular, it can be provided that the first magnetic flux and the second magnetic flux together exert an adhesive force on the first connecting unit when the tablet computer unit is positively received in the recess. The amount of the adhesive force can, for example, be greater than 100 grams, in particular greater than one kilogram, in particular greater than 10 kilograms.
[0010] In addition to the magnetic regions of the first set, the second connection unit can have further magnetic regions, each of which faces the recess with its north pole. In addition to the magnetic regions of the second set, the second connection unit can have further magnetic regions, each of which faces the recess with its south pole. In particular, an absolute amount of magnetic flux through the cladding in the region of the recess, which all magnetic regions of the second connection unit, each of which faces the recess with its north pole, generate together, can be significantly greater or significantly smaller than an absolute amount of magnetic flux through the cladding in the region of the recess, which all magnetic regions of the second connection unit, each of which faces the recess with its south pole, generate together.
[0011] The fact that the absolute amount of the first magnetic flux through the cladding in the region of the depression is substantially equal to an absolute amount of the second magnetic flux through the cladding in the region of the depression has the effect that the first magnetic flux and the second magnetic flux substantially compensate each other in the long-range effect and that the resulting effect of the first magnetic flux and the second magnetic flux on the first connecting unit decreases very rapidly with increasing distance between the first connecting unit and the second connecting unit.
[0012] The magnetic force connection therefore only occurs when the ferromagnetic areas of the first connecting unit are very close to the magnetic areas of the second connecting unit. As a result, until this very close distance is reached, the positive connection between the tablet computer unit and the recess takes precedence over the magnetic force connection. The tablet computer unit can thus be quickly and easily moved toward the recess, optimally accommodated in the recess, and then secured by the magnetic connection. The arrangement thus enables an improved combination of positive connection and magnetic force connection for the holder of the tablet computer unit.
[0013] One embodiment provides that the magnetic regions of the first set and the magnetic regions of the second set are arranged alternately, in particular are arranged alternately such that for each magnetic region of the first set, the distance to a respective nearest magnetic region of the second set is smaller than the distance to a respective nearest magnetic region of the first set. One embodiment provides that the magnetic regions of the first set and the magnetic regions of the second set are arranged alternately such that for each magnetic region of the second set, the distance to a respective nearest magnetic region of the first set is smaller than the distance to a respective nearest magnetic region of the second set.
[0014] This allows the first magnetic flux and the second magnetic flux to substantially compensate each other with respect to the effect on the ferromagnetic regions of the first connecting unit at even smaller distances between the first connecting unit and the second connecting unit.
[0015] One embodiment provides that the first set of magnetic regions comprises at least three, in particular at least four, preferably at least five, magnetic regions that are spaced apart from one another and each face the recess with its north pole, and that together generate the first magnetic flux.

In particular, each magnetic region of the first set can be followed along the closed path by a magnetic region of the second set. In particular, each magnetic region of the second set can be followed along the closed path by a magnetic region of the first set. In particular, each magnetic region of the first set can be polarized substantially opposite to the magnetic region of the second set closest along the closed path.
[0021] One embodiment provides that the closed path is a circular line and / or that the area bounded by the closed path is a circular area.
[0022] According to another embodiment, the closed path is a rectangular line, for example with rounded corners, and the area bounded by the closed path is a rectangular area, for example with rounded corners.
[0023] One embodiment provides that the tablet computer unit has a first inductive energy transmission element for receiving electrical energy for the tablet computer, which is arranged in a region of the first connection unit. The housing part has a second energy transmission element corresponding to the first energy transmission element for providing the electrical energy for the tablet computer, which is arranged in a region of the second connection unit such that the electrical energy for the tablet computer can be transmitted through the area delimited by the closed path. This avoids open contacts for energy transmission, which significantly improves safety and cleanability.
[0024] One embodiment provides that each ferromagnetic region of the set of ferromagnetic regions of the first connecting unit is designed to be flat such that, in an operating state of the arrangement in which the tablet computer unit is positively received in the recess, each magnetic region of the first set and / or each magnetic region of the second set is polarized substantially perpendicular to a surface in which the respective nearest ferromagnetic region extends flatly.

[0028] According to an alternative arrangement, the first connecting unit comprises the first set of magnetic regions and the second set of magnetic regions instead of the set of ferromagnetic regions, with the second connecting unit comprising the ferromagnetic regions. For such an alternative arrangement, the relative position and orientation as well as the interaction of the magnetic regions and / or the ferromagnetic regions can be configured analogously to one of the aspects disclosed in connection with the claimed arrangement.

[0032] According to one embodiment, the edge region of the recess is configured to correspond to an edge region of the tablet computer unit such that, starting from an operating state of the arrangement in which the tablet computer unit is received in the recess with a form-fitting fit, the edge region of the tablet computer unit can be sunk into the edge region of the recess by means of a tilting movement of the tablet computer unit relative to the panel. In particular, the recess can have an edge region configured between the indentation for receiving the bulge and the edge region of the recess such that the tilting movement of the tablet computer unit can be carried out around the edge region. In particular, the indentation of the tablet computer unit can rest on the edge region of the recess.
[0033] One embodiment provides that the tablet computer unit has an indentation between the in particular flat bulge and an edge region of the tablet computer unit, in particular to improve the grip of the tablet computer unit.

[0038] The first connection unit of the housing part of the medical imaging device can be designed according to one of the embodiments disclosed in particular for the first connection unit of the tablet computer unit. The second connection unit of the tablet computer unit can be designed according to one of the embodiments disclosed in particular for the second connection unit of the housing part of the medical imaging device.
[0039] One embodiment provides that the arrangement comprises the medical imaging device.
[0040] The medical imaging device can, for example, be selected from the imaging modality group consisting of an X-ray device, a C-arm X-ray device, a computed tomography (CT) device, a molecular imaging (MI) device, a single-photon emission computed tomography (SPECT) device, a positron emission tomography (PET) device, a magnetic resonance imaging (MR) device, and combinations thereof, in particular a PET-CT device and a PET-MR device. The medical imaging device can further comprise a combination of an imaging modality, selected, for example, from the imaging modality group, and an irradiation modality. The irradiation modality can, for example, comprise an irradiation unit for therapeutic irradiation.
[0041] The gantry of a medical imaging device typically has a support structure on which components of the acquisition unit, in particular the radiation source and / or the radiation detector, are arranged.

[0047] The invention is explained below using exemplary embodiments with reference to the accompanying figures. The representations in the figures are schematic, highly simplified, and not necessarily to scale.
[0048] It shows the Fig. 1 the magnetic regions of the first set and the magnetic regions of the second set in a holding device, the Fig. 2 the tablet computer unit and another example of a holding device for holding magnetic areas, the Fig. 3 the housing of the tablet computer unit with the first connection unit, the Fig. 4 and Fig. 5 more views of the tablet computer unit, the Fig. 6 the second connecting unit in a sectional view, the Fig. 7 a side of the cover facing the interior of the medical imaging device the Fig. 8 one side of the panel visible from the outside, in the area of the recess, the Fig. 9 the arrangement with the tablet computer unit and a gantry of the medical imaging device, the Fig. 10 the docking station for the tablet computer unit and the remote control, the Fig. 11 the docking station where the tablet computer unit and the remote control are located, the Fig. 12 the wall-mounted docking station on which the tablet computer unit and the remote control are located, and the Fig. 13 the arrangement with the tablet computer unit and the medical imaging device.
[0049] The Fig. 1 shows the magnetic regions MN of the first set and the magnetic regions MS of the second set, wherein the magnetic regions MN of the first set and the magnetic regions MS of the second set are arranged in the holding device HM. The holding device HM has the structures HM1 and HM2, which are designed to increase the rigidity of the holding device HM and / or form contact surfaces for fastening the holding device HM to the panel V. The holding device HM can be screwed to the panel V, for example, by means of a plurality of screws, each of which is guided through the openings HM3.
[0050] The magnetic regions MN of the first set and the magnetic regions MS of the second set are arranged alternately such that for each magnetic region MN of the first set, the distance to a respective nearest magnetic region MS of the second set is smaller than the distance to a respective nearest magnetic region MN of the first set.
[0051] The first set of magnetic domains MN comprises five magnetic domains, and the second set of magnetic domains MS comprises five magnetic domains. Each magnetic domain MN of the first set and each magnetic domain MS of the second set is a cuboid-shaped permanent magnet that is flat and polarized perpendicular to a surface in which it extends.
[0052] The magnetic regions MN of the first set and the magnetic regions MS of the second set are arranged along a closed path in the shape of a circle. Each magnetic region MN of the first set and each magnetic region MS of the second set is polarized perpendicular to a circular area bounded by the closed path.
[0053] The Fig. Figure 2 shows the tablet computer unit T and another example of a holding device HM for holding magnetic areas. The tablet computer unit T comprises a tablet computer TC and the housing TJ of the tablet computer unit T.
[0054] The tablet computer TC, which has its own tablet computer housing, is located in the housing TJ of the tablet computer unit T. The housing TJ has the first connection unit N1 and the first inductive energy transfer element I1 for receiving electrical energy for the tablet computer TC. In particular, the side of the housing TJ facing away from the tablet computer TC is designed to be hygienic, for example, easy to clean and has an antimicrobial coating.
[0055] The housing TJ has a recess in the area of the screen of the tablet computer TC, allowing the user U1 to touch the touch-sensitive screen of the tablet computer TC while the tablet computer TC is located in the housing TJ. A seal is arranged between the screen of the tablet computer TC and the housing TJ to prevent contaminants from penetrating the interior of the housing TJ through a gap formed between the screen of the tablet computer TC and the housing TJ.
[0056] The first connection unit N1 has a set of ferromagnetic regions MF. The first connection unit N1 forms a flat bulge XN, which protrudes from a region of a housing TJ of the tablet computer unit T surrounding the first connection unit N1 with respect to a direction perpendicular to a surface in which the tablet computer TC extends planarly. The tablet computer unit T has an indentation YK between the flat bulge XN and the edge region XE of the tablet computer unit T. The fingertips of a hand grasping the edge region XE of the tablet computer unit T can be placed against the indentation YK, thus improving the grip of the tablet computer unit T.
[0057] The Fig. Figure 3 shows a housing TJ of the tablet computer unit T with the first connection unit N1. The ferromagnetic regions MF of the set of ferromagnetic regions MF of the first connection unit N1, in the form of metal plates, are spaced apart from one another and each have a flat design. The tablet computer unit T has a first inductive energy transmission element I1 for receiving electrical energy for the tablet computer TC, which is arranged in a region of the first connection unit N1.
[0058] In an operating state of the arrangement 1 in which the tablet computer unit T is positively received in the recess YT, each ferromagnetic region MF covers a gap corresponding to this ferromagnetic region, which gap is formed between a magnetic region MN of the first set and a magnetic region MS of the second set which is closest to this magnetic region MF of the first set.
[0059] In an operating state of the arrangement 1 in which the tablet computer unit T is positively received in the recess YT, each magnetic region MN of the first set and / or each magnetic region MS of the second set covers a gap corresponding to this magnetic region, which gap is formed between two adjacent ferromagnetic regions of the set of ferromagnetic regions MF of the first connecting unit N1.
[0060] In this way, each ferromagnetic region MF is optimally permeated by the magnetic field lines that run between the magnetic region MN of the first set and the magnetic region MS of the second set, between which the gap corresponding to this ferromagnetic region is formed. This allows the magnetic attraction force exerted by the magnetic regions of the first set and the magnetic regions of the second set on the ferromagnetic regions to be more effective.
[0061] The first connecting unit N1 has a holding device HMF for the ferromagnetic regions MF, which is flat and has an annular holding structure and a set of holding elements. These holding elements are spaced apart from one another and arranged cantilevered on the annular holding structure in the plane of the annular holding structure, each holding element being designed to accommodate a respective ferromagnetic region MF.
[0062] In an operating state of the arrangement 1 in which the tablet computer unit T is positively received in the recess YT, each magnetic region MN of the first set and each magnetic region MS of the second set is each polarized substantially perpendicular to a surface of the metal plate which forms the nearest ferromagnetic region MF.
[0063] The Fig. 4 and Fig. 5 show further views of the tablet computer unit T.
[0064] The Fig. Figure 6 shows the second connection unit N2 in a sectional view. The gantry 20 of the medical imaging device 2 comprises the cover V and the second connection unit N2. The cover V has a recess YT into which the tablet computer unit T can be positively received.
[0065] The second connection unit N2 is arranged in a region of the recess YT such that a magnetic connection can be formed by means of the first connection unit N1 and the second connection unit N2, which counteracts removal of the tablet computer unit T from the recess YT. The second connection unit N2 has a first set of magnetic regions MN, which are spaced apart from one another and each face the recess YT with their north pole and which together generate a first magnetic flux. The second connection unit N2 has a second set of magnetic regions MS, which are spaced apart from one another and each face the recess YT with their south pole and which together generate a second magnetic flux.An absolute value of the first magnetic flux through the cladding V in the region of the recess YT is substantially equal to an absolute value of the second magnetic flux through the cladding V in the region of the recess YT.
[0066] The gantry 20 has a second energy transmission element I2, corresponding to the first energy transmission element I1, for providing electrical energy for the tablet computer TC. The second energy transmission element I2 is arranged in a region of the second connection unit N1 such that the electrical energy for the tablet computer TC can be transmitted through the area delimited by the closed path. The second energy transmission element I2 is connected to the electronic module EM for wireless charging.
[0067] The Fig. 7 shows a side of the cover V facing the interior of the medical imaging device 2, in the region of the recess YT.
[0068] The Fig. Figure 8 shows a side of the panel V, visible from the outside, in the area of the recess YT. The recess YT has a recess YN for the positive reception of the bulge XN.
[0069] The Fig. 9 shows the arrangement 1 with the tablet computer unit T and the gantry 20 of the medical imaging device 2 in an operating state in which the tablet computer unit T is received in a form-fitting manner in the recess YT. The recess YT has an edge region YE in which the form-fitting reception of the tablet computer unit T is interrupted. A grip recess for gripping the tablet computer unit T is formed between the panel V in the region of the recess YT and the edge region XE of the tablet computer unit T, such that the user U1 can exert a pressure force with the palm of a hand on a side of the tablet computer unit T facing the recess YT in order to remove the tablet computer unit T from the recess YT. One such grip recess is formed in each case on an upper edge region of the recess YT and on a lower edge region of the recess YT.
[0070] Thus, it is possible for a user U1 to pull the tablet computer unit T out of the recess YT with both hands simultaneously, grasping the upper gripping recess with one hand and the lower gripping recess with the other hand. To reduce the force required to remove the tablet computer unit T, it may be advantageous for the user U1 to grasp only one of the two gripping recesses and thus exert a tilting moment on the tablet computer unit T using the pressure force of their palm, whereby a leverage effect of the tablet computer unit T is used to overcome the positive locking and the magnetic force locking.
[0071] The edge region YE of the recess YT is further designed to correspond to an edge region XE of the tablet computer unit T in such a way that, starting from the operating state of the arrangement 1 in which the tablet computer unit T is positively received in the recess YT, the edge region XE of the tablet computer unit T can be sunk into the edge region YE of the recess by means of a tilting movement of the tablet computer unit T relative to the covering V.
[0072] The recess YT has an edge region XK which is formed between the indentation YN for receiving the bulge XN and the edge region YE of the recess YT such that the tilting movement of the tablet computer unit T can be carried out around the edge region XK.
[0073] By countersinking the edge region XE of the tablet computer unit T into the edge region YE of the recess, it can be achieved that the opposite edge region of the tablet computer unit T protrudes significantly beyond the panel V of the gantry 20 and is thus easier to grasp by a user U1.
[0074] The Fig. 10 shows a docking station D for receiving the tablet computer unit T and the remote control R. For this purpose, the docking station D has a panel with a recess DYN for the positive reception of the bulge XN. The docking station D has a third connection unit, which is arranged in the region of the recess DYN such that a magnetic connection can be formed by means of the first connection unit N1 and the second connection unit N2, which prevents the tablet computer unit T from being removed from the docking station. The third connection unit is designed according to one of the embodiments disclosed for the second connection unit. The docking station D further has a recess DYR for the positive reception of the remote control R.
[0075] The Fig. 11 shows the docking station D, on which the tablet computer unit T and the remote control R are arranged. The docking station D is mounted on a support device HD for inclined support of the docking station D, so that the screen plane of the tablet computer TC is inclined relative to the table surface S. This enables improved use of the tablet computer TC in terms of ergonomic aspects. The support device HD can also be designed for adjusting, for example, for stepped or continuous adjustment, the angle of inclination between the screen plane of the tablet computer TC and the table surface S.
