Playing with 3D medical dataset

The Image3D containers are to be replaced by the Image3DAlt, but these examples are still valid.

• Open a local Minc2 file, extract 3 orthogonal slices and display in canvas | source
• Open a local NIfTI file, extract 3 orthogonal slices and display in canvas | source
• Open a local MGH file, extract 3 orthogonal slices and display in canvas | source
• Open a *.pixp containing an Image3D file and display 3 otho slices | source
• Convert a NIfTI/MINC/MGH file to a pixp file | source
