Thanks

I wonder if you know a way to remove the black regions visible on the slices in the 3D view? I would like the view to look like the head was being sliced, but without the black areas.

Thanks again in advance for your help

You can hide black region from the slice view by setting Volumes module / Display section / Threshold (increase the lower limit of the threshold until the border disappears).
