摘要： A 3D result image of an object is reconstructed from a set of X-ray two-dimensional projections of the object. A 3D reference image of the object is reconstructed by employing a compressed sensing technique based on at least some of the 2D projections at a reference motion state of the object. By employing an algebraic and/or analytic reconstruction technique, 3D intermediate images are reconstructed for various motion states of the object. The 3D intermediate images are registered with the 3D reference image to obtain spatial transformations for the various motion states of the object. Based on the spatial transformations, the 3D intermediate images are transformed to a joint phase and combined to obtain the 3D result image.

摘要： The invention relates to a method for three-dimensional presentation of a moved structure using a tomographic method, in which a plurality of projection images are recorded from different imaging angles between a start angle with a start node point and an end angle with an end node point by an imaging unit during a number of rotation passes, with three-dimensional image data being able to be reconstructed from the projection images, with the projection images being spaced by a path or an edge. For determining the three-dimensional presentation for each angle of projection only those projection images are selected which minimize the sum of the paths or weighted edges between adjacent projection angles for a gating.
