Device and method for contactless control of a patient table

1. A device for contact-free control of a patient table that is movably mounted on a table base so as to be movable relative to a patient receiving opening of a medical examination apparatus, said device, comprising:

a camera that detects at least one gesture made by a person that corresponds in direction or shape to a desired movement of said patient table relative to said opening, and that converts said gesture into image data that represents said at least one gesture;

a computer processor in communication with said camera that receives said image data from said camera and is configured to convert said image data representing said at least one gesture into at least command for controlling movement of the patient table;

an execution unit in communication with said computer processor that is provided with said command and that is configured to generate and emit a control signal to execute said at least one command that produces a movement of the patient table, relative to said patient-receiving opening, corresponding to said at least one command; and

a monitoring system comprising a projector configured to project, at a projection site within a field of view of said person, a projected image of said patient table executing said movement, and thereby allowing said person to alter said movement executed by said table, if said movement executed by said table does not correspond to said desired movement, by making another gesture that is detected by said camera and converted into further image data that are converted into at least one further command provided to said execution unit, which alters said movement of said patient table.

2. A device as claimed in claim 1 comprising an authentication system configured to authenticate the person making such at least one gesture.

3. A device as claimed in claim 2 wherein said authentication system is configured to automatically authenticate said person by at least one optical marker associated with said person.

4. A device as claimed in claim 3 wherein said optical marker is an accessory worn by said person.

5. A device as claimed in claim 2 wherein said authentication system is configured to authenticate said person by detecting an authentication gesture made by said person.

6. A device as claimed in claim 2 wherein said authentication system is configured to authenticate said person by reading a chip card associated with said person.

7. A device as claimed in claim 2 wherein said authentication system is configured, after authenticating said person, is configured to orient said camera to a location of said person.

8. A device as claimed in claim 1 wherein said patient table and said camera is situated in a different room from the patient table.

9. A device as claimed in claim 1 wherein said camera is integrated into the patient table.

10. A device as claimed in claim 1 wherein said camera is situated remotely from the patient table, as a component of a monitoring system that monitors control of the patient table by the execution unit.

11. A device as claimed in claim 10 wherein said monitoring system comprises a projector that projects an image that designates a position of the patient table.

12. A method for contact-free control of a patient table that is movably mounted on a table base so as to be movable relative to a patient receiving opening of a medical examination apparatus, said device, comprising:

operating a camera to detect at least one gesture made by a person that corresponds in direction or shape to a desired movement of said patient table relative to said opening and converting said gesture into image data that represents said at least one gesture;

providing said image data to a computer processor in communication with said camera and, in said computer processor, converting said image data representing said at least one gesture into at least command for controlling a patient table;

in an execution unit in communication with said computer processor that is provided with said command, generating and emitting a control signal that causes said at least one command to be executed by producing a movement of the patient table relative to said patient-receiving opening corresponding to said at least one command; and

with a projector, projecting, at a projection site within a field of view of said person, a projected image of said patient table executing said movement, and thereby allowing said person to alter said movement executed by said table, if said movement executed by said table does not correspond to said desired movement, by making another gesture that is detected by said camera and converted into further image data that are converted into at least one further command provided to said execution unit, which alters said movement of said patient table.

13. A method as claimed in claim 12 comprising authenticating said person via an authentication unit.

14. A method as claimed in claim 12 comprising monitoring control of said patient table via a monitoring unit that is situated remotely from said patient table.

15. A method as claimed in claim 12 comprising integrating said camera into said patient table.

16. A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a control computer for contact-free control of a patient table that is movably mounted on a table base so as to be movable relative to a patient receiving opening of a medical examination apparatus, said device, said programming instructions causing said control computer to:

operate a camera to detect at least one gesture made by a person that corresponds in direction or shape to a desired movement of said patient table relative to said opening and convert said gesture into image data that represents said at least one gesture;

convert said image data representing said at least one gesture into at least command for controlling a patient table;

operate an execution unit according to said command so as to generate and emit a control signal that executes said at least one command by producing a movement of the patient table relative to said patient-receiving opening corresponding to said at least one command; and

operate a projector in order to project, at a projection site within a field of view of said person, a projected image of said patient table executing said movement, and thereby allowing said person to alter said movement executed by said table, if said movement executed by said table does not correspond to said desired movement, by making another gesture that is detected by said camera and converted into further image data that are converted into at least one further command provided to said execution unit, which alters said movement of said patient table.
