Method for controlling an x-ray device and x-ray device

An X-ray device comprising:

• an X-ray source;
• an X-ray detector;
• a light guiding device;
• and
• a controller,
• wherein the X-ray source and the X-ray detector are arranged opposite one another and in a first defined arrangement,
• wherein the first defined arrangement is movably mounted,
• wherein the light guiding device is arranged in a second defined arrangement with respect to the X-ray detector,
• wherein the second defined arrangement is at least rotatably mounted,
• wherein a virtual reference beam is defined by a first reference point and a second reference point,
• wherein the first reference point is arranged at the X-ray source, and the second reference point is arranged between the X-ray source and the X-ray detector as part of the first defined arrangement,
• wherein the light guiding device is configured to emit the light fan, such that the virtual reference beam is arranged within the light fan,
• wherein the controller is configured to:
• receive the planning information for the planned path for arranging the medical object that is mappable by the X-ray device;
• and
• reposition the first defined arrangement from the initial position to the further position, wherein the virtual reference beam intersects the planned path in the initial position and the further position of the first defined arrangement;
• capture the further position as the current position of the first defined arrangement;
• and
• rotate the second defined arrangement based on the planning information and the current position of the first defined arrangement, such that the light fan illuminates the planned path.

In a non-transitory computer-readable storage medium that stores instructions executable by one or more processors to control an X-ray device, wherein the X-ray device comprises an X-ray source, an X-ray detector, and a light guiding device, wherein the X-ray source and the X-ray detector are arranged opposite one another and in a first defined arrangement, wherein the first defined arrangement is movably mounted, wherein the light guiding device is arranged in a second defined arrangement with respect to the X-ray detector, wherein the second defined arrangement is at least rotatably mounted, wherein a virtual reference beam is defined by a first reference point and a second reference point, wherein the first reference point is arranged at the X-ray source, and the second reference point is arranged between the X-ray source and the X-ray detector as part of the first defined arrangement, the instructions comprising:

• receiving planning information for a planned path for arranging a medical object that is mappable by the X-ray device;
• emitting a light fan by the light guiding device, such that the virtual reference beam is arranged within the light fan;
• repositioning the first defined arrangement from an initial position to a further position, wherein the virtual reference beam intersects the planned path in the initial position and the further position of the first defined arrangement;
• capturing the further position as the current position of the first defined arrangement;
• and
• rotating the second defined arrangement based on the planning information and the current position of the first defined arrangement, such that the light fan illuminates the planned path.
