[0007] In particular, it may be provided that the first side wall and the second side wall project relative to the bearing surface in such a way that their area moment of inertia counteracts any bending of the bearing surface about a transverse axis of the support structure. In particular, it may be provided that the bearing surface extends along a transverse axis of the support structure from the first side wall to the second side wall and / or that the transverse axis of the support structure is perpendicular to the longitudinal axis of the support structure.

[0010] In this way, handles can be designed that allow for easy transport as well as easy insertion and / or removal of the storage structure at designated interfaces.
[0011] One embodiment provides that the storage structure has a first connecting unit and a second connecting unit for a connection, in particular for a hook and loop connection, with a retaining strap, wherein the first connecting unit is attached to the first side wall and the second connecting unit is attached to the second side wall in such a way that the first side wall, the retaining strap, the second side wall and the support surface together form a completely closed contour when the retaining strap is connected to the first connecting unit and to the second connecting unit.

In particular, it can be provided that the system axis SA is horizontal and / or that the translational direction is horizontal. Specifically, it can be provided that the longitudinal axis of the support structure 8 is substantially parallel to the translational direction if, by means of the second device-side interface AC and the support-side interface C, the second detachable connection is established, which fixes the support structure 8 relative to the gantry 20 such that the longitudinal axis of the support structure 8 is perpendicular and skew to the system axis SA.
[0053] The example shown provides that the computed tomography device 1 has a holding structure N for the support structure 8, - wherein a first substructure A of the holding structure N has the second device-side interface AC, - wherein the second gantry part 22 has a recess 28 for the positive-locking reception of the retaining structure N such that the first substructure A of the retaining structure N protrudes from the recess 28 when the retaining structure N is positively locked into the recess 28.
[0054] In particular, it can be provided that a contact surface of the second substructure BC of the retaining structure N rests on a bottom of the recess 28 when the retaining structure N is positively engaged in the recess 28.
[0055] The recess 28 is formed below the warning lamp L. In the Fig. Figure 7 shows the computed tomography scanner 1 with two support structures 8. The object under investigation 13 is positioned on one of the two support structures 8 for examination using the computed tomography scanner 1.
[0056] The Fig. Figure 8 shows the recess 28 for the positive-locking reception of the retaining structure N. Fig. Figure 9 shows the support structure N in a first orientation. Fig. Figure 10 shows an arrangement of the bearing structure 8 on the gantry 20 with the aid of the holding structure N. Fig. Figure 11 shows the support structure N in a second orientation. Fig. Figure 12 shows an arrangement of the storage structure 8 on a table top using the holding structure N.
[0057] The example shown provides that a second substructure B of the holding structure N has a table-side interface BC, - wherein a third detachable connection can be established by means of the table-side interface BC and the bearing-side interface C, which fixes the bearing structure 8 relative to the holding structure N in such a way that the longitudinal axis of the bearing structure 8 is essentially Parallel to a tabletop, the holding structure N is positioned on the tabletop such that a contact surface of the first substructure A of the holding structure N rests against the tabletop. The contact surface of the first substructure A of the holding structure N and the contact surface of the second substructure B of the holding structure N can, in particular, be plane-parallel.
[0058] The example shown provides that the support structure N has a first leg area N1, a second leg area N2 and a crown area N3, - wherein the apex area N3 has the second device-side interface AC and / or the table-side interface BC and extends from the first leg area N1 to the second leg area N2, - wherein the first leg region N1 and the second leg region N2 extend parallel to the longitudinal axis of the support structure 8 away from the apex region N3 when the second detachable connection or the third detachable connection is made.
[0059] The retaining structure N is U-shaped. Between the first leg section N1 and the second leg section N2, the retaining structure N has a recess N0. The first leg section N1 has a grip recess P1, which is open towards the recess N0. The second leg section N2 has a grip recess P2, which is also open towards the recess N0.
[0060] This allows the holding structure N to be gripped more securely, for example to insert it into or lift it out of the recess 28. If, for example, labels are attached to the bottom of the recess 28, these are visible from above through the recess.
[0061] For example, the holding structure may be provided with at least one further second device-side interface, which is offset from the second device-side interface AC, for example, closer to one of the two leg regions than to the other. For example, the holding structure may have three further second device-side interfaces, which are arranged side by side along the apex region.
[0062] The support structure 8 can then be fixed transversely to the longitudinal axis of the support structure 8 relative to the holding structure N, for example to allow easier access to the support structure 8.
[0063] In the Fig. 11 is the holding structure N rotated 180 degrees relative to the one in the Fig. The orientation of the support structure N shown in 9 is rotated. This is due to the fact that in the Fig.The orientation of the leg sections N1, N2 relative to the support structure 8, as shown in Figure 11, counteracts tipping of the support structure 8 when the holding structure N with the support structure 8 fixed to it is placed on a tabletop. If the holding structure N is positively engaged in the recess 28, a positive fit between the holding structure N and the edges of the recess 28 counteracts tipping. In particular, this positive fit can be designed such that removal of the holding structure N from the bottom of the recess 28 is only possible by vertically lifting the holding structure N relative to the recess 28.
[0064] The second device-side interface AC has interface elements AC1 and AC2. The table-side interface BC has interface elements BC1 and BC2.
[0065] The bearing-side interface C has the interface element C2, which is configured to correspond to the interface elements AC2 and BC2. The bearing-side interface C has a further interface element, which is configured to correspond to the interface elements AC1 and BC1.
[0066] The bearing-side interface C features interface element C3 in the form of a projecting shoulder. The second device-side interface AC has a contact surface for a positive fit with interface element C3.
