1. An imaging apparatus for irradiating an object with x-rays, the imaging apparatus comprising: a source arrangement, from which x-rays are operable to be emitted from different positions, the different positions forming an at least one-dimensional structure; a detector arrangement for detecting the x-rays originating from the source arrangement and emitted onto the detector arrangement, wherein an object to be irradiated is operable to be arranged between the source arrangement and the detector arrangement, so that the x-rays attenuated by the object are operable to be recorded with the detector arrangement; and an evaluation apparatus for evaluating the signals recorded by the detector arrangement, wherein a region of the detector arrangement is assigned to different positions of the one-dimensional structure, from which x-rays are directed at the region in partial irradiations, wherein the total of the dimension of the one-dimensional structure and the dimension of the region is greater than or equal to 2, and wherein the region is aligned relative to the one-dimensional structure, such that the partial irradiations, which are produced from the different positions of the one-dimensional structure with respect to the region of the detector arrangement, produce a radiation geometry that irradiates the object in a planar fashion.
