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