Abstract
The invention relates to a computer tomography method, in which a periodically moving object, especially a heart, is irradiated by a beam bundle. In that process, intermediate images of one and the same subregion of the object are reconstructed using measured values from time intervals from different periods. That is, in each case exactly one period can be allocated to each intermediate image. The time intervals in the individual periods are adjusted in such a way that, after a reconstruction of the intermediate images using measured values that lie in the adjusted time intervals, a similarity measure applied to the intermediate images of the same subregion is minimized. This method can be applied to one, several or all subregions of the object that are reconstructable using measured values from time intervals from different periods. Finally, a computer tomography image is reconstructed, wherein exclusively measured values from the adjusted time intervals are used.
