You might also find ACPC Transform module useful, which can reorient an image to make the midsagittal plane exactly aligned with the sagittal view.

Short demo/tutorial video:

> I did a quick recording of how ACPC alignment works in latest Slicer Preview Release: [[acpcdemo] ](https://www.youtube.com/watch?v=sdrRv3JrgTU) It would be great if you could create a nice description/tutorial of how to use it (with a few screenshots). Slicer documentation is now in markdown format, which is the format that this forum uses, so you can write this as a new post in this topic and I will move it to the Slicer documentation when it is ready.
