1. A method for providing a three-dimensional (3D) image dataset of an examination object, the method comprising:
recording a plurality of first projection images of the examination object, wherein the plurality of first projection images map the examination object along mutually different first projection directions;
recording a corresponding respective second projection image of the examination object for at least two first projection images of the plurality of first projection images, wherein each first projection image of the plurality of first projection images has a first focus point, and the second projection images each have a second focus point, wherein each of the second projection images together with the respective first projection images corresponding thereto at least partially map a common part of the examination object about a stationary center point, wherein the second projection images map the examination object along second projection directions that are mutually different and, in relation to the respective corresponding first projection directions, at least partially different, such that a straight line through the first focus point and the second focus point of the mutually corresponding first projection images and second projection images extends through the stationary center point;
reconstructing the 3D image dataset from the plurality of first projection images and the second projection images; and
providing the 3D image dataset.
