Abstract

Device for generating a view of a three-dimensional object

Claims

1-7. -7. (canceled)

8. A device for generating a view of a three-dimensional object, comprising:

a plurality of adjacently arranged light source groups, each light source group including a plurality of light sources and assigned to an image pixel of the view, the light sources assigned to a specific radiation direction and arranged and configured to emit light substantially in one direction; and

a control unit for controlling the light sources assigned to the specific radiation direction based on a view of the three-dimensional object as seen in the radiation direction, wherein

the light emitted by the light sources of one of the light source groups is concentrated into beams partially illuminating an optical element arranged in front of the respective light source group relative to the radiation direction, the optical element adapted to deflect the beams into the radiation direction.

9. The device as claimed in claim 8, wherein a dispersion of the beams transversely to a main beam direction is limited by a screen device operatively connected to the light sources.

10. The device as claimed in claim 8, wherein the light sources are adapted to emit laser radiation.

11. The device as claimed in claim 10, wherein the light sources are surface emitting semiconductor lasers.

12. The device as claimed in claim 8, wherein the optical element is an optical lens defining one image pixel.

13. A method of displaying a view of a three-dimensional medical data record, comprising utilizing a view generation device, the view generation device comprising:

a plurality of adjacently arranged light source groups, each light source group including a plurality of light sources and assigned to an image pixel of the view, the light sources assigned to a specific radiation direction and arranged and configured to emit light substantially in one direction; and

a control unit for controlling the light sources assigned to the specific radiation direction based on a view of the three-dimensional object as seen in the radiation direction, wherein

the light emitted by the light sources of one of the light source groups is concentrated into beams partially illuminating an optical element arranged in front of the respective light source group relative to the radiation direction, the optical element adapted to deflect the beams into the radiation direction.

14. A method of visualizing a view of a three-dimensional medical data record acquired by an X-ray tomograph or a manetic resonance tomograph, comprising utilizing a visualization device, the visualization device comprising:

a plurality of adjacently arranged light source groups, each light source group including a plurality of light sources and assigned to an image pixel of the view, the light sources assigned to a specific radiation direction and arranged and configured to emit light substantially in one direction; and

a control unit for controlling the light sources assigned to the specific radiation direction based on a view of the three-dimensional object as seen in the radiation direction, wherein

the light emitted by the light sources of one of the light source groups is concentrated into beams partially illuminating an optical element arranged in front of the respective light source group relative to the radiation direction, the optical element adapted to deflect the beams into the radiation direction.
