X-ray imaging system with foreign object reduction

A method for imaging an object by an X-ray imaging system, the method comprising:

• determining presence of at least one foreign object located in the object or located between a surface of the object and at least one of the X-Ray radiation source and the X-ray detector;
• obtaining a three-dimensional profile of the determined foreign object from a server-based foreign object database;
• and
• reconstructing an image of the object by acquiring a plurality of projection images of the object from the X-ray detector and reducing impact on image quality of an artefact caused by the foreign object in the image of the object based on at least the obtained three-dimensional profile of the foreign object;
• wherein the artefact is at least partly subtracted from the image of the object.

A non-transitory computer-readable medium for storing executable instructions, when executed by processing circuitry, cause the processing circuitry to perform a method for for imaging an object by an X-ray imaging system, the method comprising:

• determining presence of at least one foreign object located in the object or located between a surface of the object and at least one of the X-Ray radiation source and the X-ray detector;
• obtaining a three-dimensional profile of the determined foreign object from a server-based foreign object database;
• and
• reconstructing an image of the object by acquiring a plurality of projection images of the object from the X-ray detector and reducing impact on image quality of an artefact caused by the foreign object in the image of the object based on at least the obtained three-dimensional profile of the foreign object, wherein the artefact is at least partly subtracted from the image of the object.
