Abstract
A method is claimed for correcting truncation artifacts in a tomography method, wherein internal checkpoints having a low level of attenuation are selected within the projection image and external checkpoints are defined by extrapolation based on the internal checkpoints. An adaptation function is then tailored to the internal checkpoints and the external checkpoints. This allows truncation artifacts to be effectively suppressed during the reconstruction of sectional images.
