System and method for correlating object information with X-ray images

1. A system for displaying an image, the system comprising:

at least one X-ray source for emitting radiation;

a detector for acquiring the radiation emitted by said at least one X-ray source for generating an X-ray image, said detector being disposed opposite said at least one X-ray source relative to an object to be examined;

a display device for displaying X-ray images acquired by said detector;

at least one detector-side data acquisition unit for acquiring surface information of an exterior surface of the object to be examined, said at least one detector-side data acquisition unit including at least one camera with a distance measuring unit;

a computer unit for carrying out computational operations, said computer unit being configured to correlate data acquired by said at least one detector-side data acquisition unit with the X-ray image; and

a projection device connected to said computer unit and configured to project a visible image related to the X-ray image onto the exterior surface of the object to be examined.

2. The system according to claim 1 , wherein said at least one detector-side data acquisition unit includes at least one laser device.

3. The system according to claim 1 , which further comprises a projection device for projecting at least one visible marker selected from the group consisting of points, lines, contours and areas onto the object to be examined.

4. The system according to claim 3 , which further comprises an input unit for processing the X-ray image displayed on said display device in order to determine the at least one of points, lines, contours or areas to be projected.

5. The system according to claim 1 , wherein said at least one detector-side data acquisition unit is disposed outside a radiation region of said at least one X-ray source.

6. The system according to claim 1 , wherein said at least one detector-side data acquisition unit is configured to acquire at least one of brightness information, color information, position information or depth information.

7. A method for correlating acquired surface data of an object to be examined with an X-ray image, the method comprising the following steps:

generating an X-ray image of the object to be examined;

acquiring surface information of the object to be examined using a detector-side data acquisition unit by recording a surface using at least one first camera for acquiring the surface information;

determining a distance between a point on the surface of the object and the camera;

determining a projection of the point in the X-ray image; and

correlating acquired surface data with the generated X-ray image, superimposing the correlated surface data with the generated X-ray image, and projecting a visible image related to the correlated surface data onto the object.

8. The method according to claim 7 , wherein the surface data are color information or depth information.

9. The method according to claim 7 , which further comprises the following steps:

recording the surface of the object by using the at least one first camera in the form of two cameras disposed at a distance from one another; and

calculating the surface information from data obtained by the cameras.

10. The method according to claim 7 , which further comprises the following steps:

traversing the surface of the object with a light line;

recording the light line by using the at least one first camera; and

calculating the surface information from data obtained by the at least one first camera.

11. The method according to claim 7 , which further comprises the following steps:

creating at least one of points, lines, contours or areas at an input unit; and

projecting the created at least one of points, lines, contours or areas onto the object to be examined.
