摘要： A method for the presentation of image data (1) representing a three-dimensional object (7) in an area, wherein projection data is produced by numerically overlaying several image planes, said projection data representing a two-dimensional projection (6) of the object (7). The projection (6) is represented on a screen for perusal by a user. A partial area (8) is selected from amongst said projection (6). A detailed image (9) is created inside the partial area (8) either directly or indirectly referring back to the image data (9). The information of the detailed picture (9) is different from that of the projection (6). The detailed image (9) is represented on the screen inside said partial area (9).

摘要： 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.

摘要： The invention relates to a method for reducing interference (12) caused by artifacts (10) in medical sectional images, which are particularly generated by computer tomography, whereby a sectional image projection (A') is generated in a first step. Detection of the artifacts (10) then occurs to generate an artifact projection (B'). A reduced projection (C') is generated by combination of the sectional image projection (A') and the artifact projection (B'). A reduced sectional image (C) is generated by back projection of the reduced projection (C') in which the interference (12) is significantly reduced.
