摘要:
A method and energy-sensitive CT device are disclosed for motion correction of a computed tomography image. In an embodiment, the method includes: provisioning spectral CT data of an examination region with a moving object, the spectral CT data being recorded with an energy-sensitive CT device and including CT data at at least one energy level, and the at least one energy level of the CT data being adapted to a structure in the moving object; identifying the structure in the CT data at at least one energy level, of the at least one energy level, adapted to the structure; calculating a motion vector field of the structure identified; and motion correcting the spectral CT data by the motion vector field calculated to produce a motion-corrected CT image.
