Abstract
For creation of a movement-compensated image reconstruction in an x-ray based imaging method an optimal object movement trajectory is determined by application of a trained algorithm to an optimal latent vector and the movement-compensated image reconstruction is created depending on projection images, with the assumption that the object would have moved in accordance with the optimal object movement trajectory while the imaging method was being carried out. The optimal latent vector is determined by a predetermined cost function being minimized using the latent vector as an optimization parameter, wherein for each optimization step with a current latent vector, a current object movement trajectory is determined by application of a trained algorithm to the current latent vector, and a current value of the cost function is computed depending on the plurality of projection images, with the assumption that the object would have moved in accordance with the current object movement trajectory while the imaging method was being carried out.
