The invention relates to a method for producing a sectional image of an object consisting of artefacts (28), wherein two-dimensional image data is, for example, produced with the aid of a computer tomograph. Two-dimensional image data is produced from various projection devices (20, 22). According to the invention, pixels, which have a disruptive data value caused by the artefact, are detected. The thus defected pixels are combined to form image areas (30). In a next step, the image areas (30) are filled by means of filling methods and corrected image data is thus produced. The cross-sectional image of the object is produced on the basis of the corrected image data by retroprojection, for example. |
