1. Method for generation of a tomosynthetic 3D x-ray image, comprising:
- acquiring a plurality of 2D projection images with a stationary x-ray source that has a plurality of emitters that are arranged in parallel and can be activated individually by acquiring said 2D projection images in succession from different directions respectively associated with the individual emittersgenerating at least one 2D projection image from a plurality of individual images that are respectively created by exposure of the examination subject with a single dose that is emitted by a single emitter; and
reconstructing a tomosynthetic 3D image form said plurality of 2D projection images.

Abstract
In a method and device for producing a tomosynthetic 3D x-ray image, a number of 2D projection images of an examination subject are acquired using a fixed x-ray source. The x-ray source has multiple, individually controllable emitters that respectively emit a single x-ray dose from various different directions. The tomosynthetic 3D image is reconstructed from the individual 2D projection images, and at least one 2D projection image is composed of multiple individual images.
