How to set which Anatomical plane the imported image is

Please help me finish my project.
I got hope from my first question below and proceeded to develop with vtk, but I am losing hope.

Import multiple images using vtkImageImport

Hello. I have to implement MPR using VTK. With the help of my last question, I succeeded in converting PixelData (c-style) read with a third-party DicomReader to vtkImageData using vtkImageImport. However, I want to load multiple images (series). How can I import multiple c-style images using vtkImageImport? I lack knowledge of VTK and 3D MPR. Thank you.
