ABSTRACT:
The invention relates to a computed tomography method in which a periodically moving object is irradiated by a conical beam bundle. An nPi-relative movement is generated between a radiation source, which generates the conical beam bundle, and the object. During the nPi-relative movement, measured values are acquired, which depend on the intensity in the beam bundle on the other side of the object and from these measured values filter values are determined, which are divided into different groups. The filter values of at least one group are weighted in dependence on the movement of the object, wherein, when filter values of several groups are weighted, filter values of different groups are weighted differently in dependence on the movement of the object. Finally, a CT image of the object is reconstructed from the filter values.
