There are many options, for example:
- Option A: Reformat module can be used to adjust angles of slice views using sliders
- Option B: Show reslice widget in slice view and then adjust reslice plane in 3D views:
- Option C: Use recent Slicer preview release, show slice intersections, and use Ctrl+Alt+Left-click-and-drag to rotate intersecting slice views around the slice intersection point.
