METHOD FOR PRODUCING AN X-RAY IMAGE
First Claim
1. A method for creating an x-ray image of an object by means of an x-ray device, wherein during one at least partial circulation, an x-ray source and an x-ray detector are moved around the object, wherein the x-ray beams generated by the x-ray source and passing through the object are detected from several different directions by means of the x-ray detector, characterized in that at least one optical camera records the object during the circulation, and at least one first optical image is created, wherein the at least one optical camera has a known and defined positional relationship to the x-ray source and/or to the x-ray detector, wherein the at least one first optical image is used to determine a movement trajectory of the x-ray detector relative to the object, wherein the at least one optical camera is fixedly mounted on the x-ray detector.

Abstract
The invention relates to a method for producing an x-ray image (1) of an object (2) by means of an x-ray device (3). An x-ray source (4) and an x-ray detector (5) are moved about an object (2) during an at least partial circulation (8, 9), and the x-ray beams (10) which are generated by the x-ray source (4) and pass through the object (2) are detected from multiple different directions by means of the x-ray detector (5). In the process, at least one optical camera (13, 14) captures the object (2) during the circulation, wherein an optical image (15, 17) is produced. The optical camera (13, 14) has a rigidly defined position relative to the x-ray source (4) and/or the x-ray detector (5). The optical image (15, 17) is then used to determine a movement trajectory of the object (2) relative to the x-ray source (4) and/or the x-ray detector (5).

8. An apparatus, comprising:
-
an x-ray source constructed to emit x-ray beams towards an object; an x-ray detector constructed to detect x-ray beams; and an optical camera mounted on the x-ray detector with a known and defined positional relationship to the x-ray source and/or to the x-ray detector, wherein the x-ray source and the x-ray detector are configured to at least partially rotate about the object, wherein at least a portion of the x-ray beams emitted by the x-ray source pass through the object and are detected from different directions by the x-ray detector, wherein the optical camera records the object during the at least partial rotation to create at least one first optical image, and wherein the at least one first optical image is used to determine a movement trajectory of the x-ray detector relative to the object.
