A method and system provides medical image processing and 3-dimensional image construction of an examination subject. A user is enabled to selectively orient an x-ray imaging system having a variable 3-dimensional acquisition axis relative to an examination subject support for holding an examination subject. A non-planar image data acquisition path is set for the x-ray imaging system oriented around the variable 3-dimensional acquisition axis in response to user instruction. Acquisition of image data of the examination subject is initiated by the x-ray imaging system at a plurality of points along the non-planar image data acquisition path. A 3-dimensional image is constructed from the acquired image data such that any metal artifacts introduced by radio-opaque objects within the examination subject are minimized. The 3-dimensional image is displayed.
