In industrial CT, objects are often reconstructed from a circular scan trajectory. This reconstruction is possible even if only half of the object is visible in the detector at any given time, but at the cost of redundancies that can be used for the correction of miscalibrations. We propose a scheme for recalibration using only a sinogram of projec...

In computed tomography (CT) reconstruction, ring artifacts emerge from incorrectly normalized or defective detector elements. Correction algorithms often introduce blur or do not correctly accommodate the behaviour of those artifacts. Normalization errors stem from noise in the detector images during the normalization process and are always present...
