Abstract
A method is provided for producing a high-resolution three-dimensional digital subtraction angiography image of an examination object. The method includes: providing or recording of a data set of a three-dimensional rotational run of an imaging system around the examination object without administration of contrast agent (e.g., mask run); motion compensation of the data set of the mask run by a method based on the epipolar consistency conditions; providing or recording of a data set of a three-dimensional rotational run of the imaging system around the examination object with administration of contrast agent (e.g., fill run); motion compensation of the data set of the fill run by a method based on the epipolar consistency conditions; reconstructing a first volume from the compensated data set of the mask run (e.g., mask volume) and a second volume from the compensated data set of the fill run (e.g., fill volume); rigid 3D-3D registration of the first volume and second volume relative to one another; and calculating a high-resolution three-dimensional digital subtraction angiography image by subtracting the mask volume from the fill volume.
