How to use the Reconstruction function to correct doubling by applying a manual correction.
Why apply an Axis of Rotation Correction?
If a scan's automatic reconstruction has doubling or blurring, the user can attempt to resolve this by applying a manual axis of rotation correction. See below for an example of a scan with doubling (left) and the same scan after axis of rotation correction (right):
How to apply an Axis of Rotation Correction.
We have included a video to show the steps required. These steps are:
- Click the Correct function in the toolbar.
- Toggle on the Axis of Rotation Correction option in the first step of the workflow.
- Move the upper and lower line into positions that intersect the part near the top and bottom of the part.
- Select a set of coarse parameters that minimize any visible doubling in both panels of the viewer.
- Repeat this step for the fine parameters.
- Start the reconstruction.
- A new volume will be returned with corrected doubling within an hour, often within around 30 minutes.
