Technical Field

[0003] Furthermore, it would be advantageous to be able to adapt the body support device to the shape and / or size of the bed used to support the human body with minimal effort. This requirement is particularly present in computed tomography systems that, while having a relatively small opening adapted to the shape of a juvenile and / or adult head, can also be used as head and / or body scanners for infants and / or small children.

The example shown proposes that the support part 5 is a first support part 51, the support part pivot device 50 is a first support part pivot device 510, and the support part pivot axis 5A is a first support part pivot axis 51A,

[0069] - wherein the body support device 75 has a second support portion 52 and a second support portion pivoting device 520,

[0070] wherein the second support portion 52 is pivotably supported relative to the machine frame 20 about a second support portion pivot axis 52A by means of a second support portion pivot device 520, so that when the pallet 7 is in the preparation position of the pallet 7, the second support portion 52 can be moved relative to the machine frame 20 from a transport position of the second support portion 52 to an inspection position of the second support portion 52 by a first pivoting movement of the second support portion 52 about the second support portion pivot axis 52A,

[0071] - wherein the first support portion pivot axis 51A and the second support portion pivot axis 52A are spaced apart from each other along the tray pivot axis 7A and are substantially parallel to each other.

[0072] The example shown suggests that the pallet 7 is pivotably supported relative to the frame 20 around the pallet pivot axis 7A by means of a pallet pivot device 70, so that when the first support part 51 is in the inspection position of the first support part 51 and the second support part 52 is in the inspection position of the second support part 52, the pallet 7 can be lowered from the preparation position of the pallet 7 to the inspection position of the pallet 7 relative to the frame 20 through the first pivoting movement of the pallet 7 around the pallet pivot axis 7A, wherein when the pallet 7 is in the inspection position of the pallet 7, the first support part 51 is in the inspection position of the first support part 51, and the second support part 52 is in the inspection position of the second support part 52, the first support part 51 and the second support part 52 jointly fix the pallet 7 in a shape-fitting manner to prevent it from falling.

[0073] The pallet pivot axis 7A is horizontal and perpendicular to the system axis SA. The pallet 7 extends flat in a pallet plane, wherein the pallet plane is substantially parallel to the pallet pivot axis 7A. Figure 2 in the position or according to Figure 3 and / or Figure 6 In the position of the support plate, the support plate plane is then in particular substantially perpendicular to the system axis SA. In particular, when the support plate 7 is in the position according to Figure 4 in the position or according to Figure 5 When the support plate 7 is in the position of the support plate 7, the support plate 7 protrudes away from the opening 9. Figure 3 The position moves to the Figure 4 , a first pivoting movement of the pallet 7 about the pallet pivot axis 7A then causes, in particular, a lowering of the pallet 7 .

[0074] According to an embodiment, Figure 2 The position of the pallet 7 shown in is the transport position of the pallet 7, Figure 3 and / or Figure 6 The position of the support plate 7 shown in FIG is the preparation position of the support plate 7, and Figure 4 The position of the pallet 7 shown in FIG is the inspection position of the pallet 7. In principle, a transport movement of the frame 20 can also be performed while the pallet 7 is in the same space-saving position of the pallet 7, which is in the Figure 3 Shown in.

[0075] exist Figure 4 In the operating state of the body support device 75 shown in FIG, the support plate 7 cannot be accidentally pivoted downwards, that is to say that the support plate 7 cannot drop. However, it is possible that the support plate 7 is pivoted upwards, that is to say that the support plate 7 raises.

[0076] The body support device 75 has a lever mechanism T, which is configured to form-fit securely secure the pallet 7 against lowering when the pallet 7 is in its standby position. The lever mechanism T has a first lever arm T1 and a second lever arm T2, and is pivotally mounted about a lever axis parallel to the pallet pivot axis 7A. The first lever arm T1 and the second lever arm T2 are rigidly connected to one another in the region of the lever axis.

[0077] exist Figure 6In the operating state of the body support device 75 shown in FIG, the lever mechanism T secures the pallet 7 in a form-fitting manner to prevent it from lowering. This is achieved by: the first lever arm T1 locks the edge region 7T of the pallet 7 with respect to the stroke required for the first pivoting movement of the pallet 7 about the pallet pivot axis 7A. By manually pressing the second lever arm T2 away from the pallet 7, the first lever arm T1 is lowered relative to the edge region 7T of the pallet 7. In this way, the stroke required for the first pivoting movement of the pallet 7 about the pallet pivot axis 7A by the edge region 7T of the pallet 7 can be released, so that the pallet 7 can be lowered relative to the machine frame 20 from the preparation position of the pallet 7 to the inspection position of the pallet 7.

[0078] In particular, it can be provided that during the preparatory pivoting movement of the pallet 7 about the pallet pivot axis 7A and / or during the further pivoting movement of the pallet 7 about the pallet pivot axis 7A, the edge region 7T of the pallet 7 is pressed away from the first lever arm T1, for example downwards, and thus opens up the following stroke, which the edge region 7T of the pallet 7 needs for the preparatory pivoting movement of the pallet 7 about the pallet pivot axis 7A and / or for the further pivoting movement of the pallet 7 about the pallet pivot axis 7A. In particular, it can be provided that the lever mechanism T is pivoted back once the pallet 7 reaches the preparatory position of the pallet 7 Figure 6 The idle position shown in FIG is pivoted, for example, in a manner driven by a torsion spring of the lever mechanism T. The torsion spring of the lever mechanism T can in particular be arranged coaxially with the lever axis.

[0079] In particular, the lever mechanism T can be designed to be substantially symmetrical relative to a vertical plane including the system axis SA. For example, the lever mechanism T can have a third lever arm arranged symmetrically relative to the first lever arm T1 and a fourth lever arm arranged symmetrically relative to the second lever arm T2. In particular, it can be provided that the holding device 72 is located between the first lever arm T1 and the third lever arm and / or between the second lever arm T2 and the fourth lever arm with respect to the lever axis.
