Abstract

An arrangement with a movable apparatus part is provided. The arrangement includes a mat-like, removable collision detection device arranged on the apparatus part and a plurality of first fasteners of the collision detection device. The plurality of first fasteners are configured to form a releasable connection with corresponding second fasteners of the apparatus part. The arrangement also includes an electrical monitoring unit configured to monitor an electrical resistance of the connection of the plurality of first fasteners to the second fasteners. A medical imaging apparatus with such an arrangement, and an associated method are also provided.

First claim

The invention claimed is:

a plurality of first fasteners arranged on the collision detection device, the plurality of first fasteners being configured to form a releasable connection with corresponding second fasteners, the second fasteners being arranged on the movable apparatus part, the collision detection device being connected to the movable apparatus part when the first fasteners are connected with the corresponding second fasteners; and
an electrical monitoring unit configured to electrically monitor an electrical resistance of the releasable connection of the plurality of first fasteners to the second fasteners.

2. An arrangement of a medical imaging device with a movable apparatus part, the arrangement comprising:
a mat-like, removable collision detection device arranged on a housing of the movable apparatus part of the medical imaging device;
a plurality of first fasteners arranged on the removable collision detection device, the plurality of first fasteners being configured to form a releasable connection with corresponding second fasteners, the second fasteners being arranged on the housing, the collision detection device being connected to the housing when the first fasteners are connected with the corresponding second fasteners; and
a monitoring unit configured to electrically monitor an electrical resistance of the connection of the plurality of first fasteners to the second fasteners.

3. The arrangement of claim 1 , wherein the plurality of first fasteners and the second fasteners are electrically conductive.

4. The arrangement of claim 2 , wherein the plurality of first fasteners and the second fasteners are electrically conductive.

5. The arrangement of claim 1 , wherein the plurality of first fasteners and the second fasteners are configured as press studs or hook-and-loop fasteners.

6. The arrangement of claim 2 , wherein the plurality of first fasteners and the second fasteners are configured as press studs or hook-and-loop fasteners.

7. The arrangement of claim 1 , further comprising:
an output unit configured to optically, acoustically, or optically and acoustically indicate the state of the connections between corresponding first fasteners and second fasteners.

8. The arrangement of claim 2 , further comprising:
an output unit configured to optically, acoustically, or optically and acoustically indicate the state of the connections between corresponding first fasteners and second fasteners.

9. The arrangement of claim 7 , wherein the output unit is configured to emit a warning signal, to stop a movement of the moveable apparatus part, or a combination thereof when the electrical monitoring unit detects an open connection between one of the corresponding first and second fasteners.

10. The arrangement of claim 8 , wherein the output unit is configured to emit a warning signal, to stop a movement of the moveable apparatus part, or a combination thereof when the monitoring unit detects an open connection between one of the corresponding first and second fasteners.

11. The arrangement of claim 3 , wherein the electrical monitoring unit is configured to determine an electrical resistance between adjacent second fasteners, and
wherein adjacent corresponding first fasteners are electrically short-circuited to each other.

12. The arrangement of claim 4 , wherein the monitoring unit is configured to determine an electrical resistance between adjacent second fasteners, and
wherein adjacent corresponding first fasteners are electrically short-circuited to each other.

13. A medical imaging apparatus comprising:
an arrangement with a movable apparatus part, the arrangement comprising:
a mat-like, removable collision detection device arranged on the movable apparatus part;
a plurality of first fasteners arranged on the collision detection device, the plurality of first fasteners being configured to form a releasable connection with corresponding second fasteners, the second fasteners being arranged on the movable apparatus part, the collision detection device being connected to the movable apparatus part when the first fasteners are connected with the corresponding second fasteners; and
an electrical monitoring unit configured to electrically monitor an electrical resistance of the releasable connection of the plurality of first fasteners to the second fasteners.

14. A method for operating a mat-like collision detection device arranged removably on a moved apparatus part of a medical imaging device, the method comprising:
electrically monitoring an electrical resistance of a connection of first fasteners arranged on the collision detection device to corresponding second fasteners arranged on the moved apparatus part.

15. The method of claim 14 , further comprising determining the electrical resistance between adjacent second fasteners,
wherein the first fasteners and the second fasteners are electrically conductive, and corresponding adjacent first fasteners are short-circuited.

16. A method for operating a mat-like collision detection device arranged removably on a housing of a moved apparatus part of a medical imaging device, the method comprising:
electrically monitoring an electrical resistance of a connection of first fasteners arranged on the collision detection device to corresponding second fasteners arranged on the housing.

17. The method of claim 16 , further comprising determining the electrical resistance between adjacent second fasteners,
wherein the first fasteners and the second fasteners are electrically conductive, and corresponding adjacent first fasteners are short-circuited.
