Patent ID: 8792702

Claim:
A method for providing a 3D image data record of a biological object with a suppressed aliasing artifact overlapping a field of view, wherein an aliasing artifact overlapping the field of view is caused by an incomplete geometric capture of the biological object by a computed tomograph, comprising: providing a first 3D image data record describing a subarea of the biological object; obtaining a second 3D image data record of the biological object by the computed tomograph, wherein the second 3D image data record includes data relating to the subarea of the biological object described by the first 3D image data record; registering the first 3D image data record with the second 3D image data record; extending and/or amending data of the second 3D image data record as a function of data of the first 3D image data record so that a part of the data of the second 3D image data record can be assigned to the aliasing artifact overlapping the field of view; and generating a modified second 3D image data record with the suppressed aliasing artifact overlapping the field of view, wherein the first 3D image data record is registered with the second 3D image data record by: positionally and dimensionally assigning the data of the first 3D image data record to the data of the second 3D image data record; determining a degree of match between the data assigned to one another; and modifying the data of the first 3D image data record assigned to the data of the second 3D image data record by draw points so that the degree of match increases.
