Tilt correction
When the turn table and detector are not aligned there will be an error in the reconstructed data. For small deviations this error can be corrected by adjusting the center of rotation for each slice. In MuhRec you have two parameters for the tilt correction. The first is the axis tilt angle and the other set the pivot point relative to the image.
The pivot is used for long samples where the turn table is located far away from the detector. For a single data set this parameter is less important than when you have several scans that you want to merge after the completed reconstruction. It is not possible to correct for both detector and pivot tilt simultaneously in the current version. The figure below shows the two different detector rotations.
