摘要：
In a tomography apparatus and method for obtaining correction values for two measurement planes, wherein the tomography apparatus an acquisition system disposed in a first measurement plane and a second acquisition system disposed in a second measurement plane that are disposed in the azimuthal direction around a common rotation axis, position correction values for both measurement planes are determined for a substantially constant rotation angle speed of the two acquisition systems using measurement values calculated at a rotation angle position of a reference object that can be introduced into both measurement planes. An artifact-free reconstruction of a slice or volume image can be made using the position correction values.
