Description

Image geometry's get_slice method ignores the slice you have given! This is the case on all axes (channel, horizontals, vertical)

Image geometry's get_slice method returns a 2D shape if slicing on 3D data

I propose to update the Image Geometry slice to:

• Get the slices at the correct locations on each axis
• Ensure voxel size in z remains correct
