I am very surprised but about that. Could you tell us what modality are 
you using ? This is highly unusual. Are you sure that you are taking to 
neighbooring slices ? Be carefull that filesname do not usually 
represent the order of the slices. Also make sure that you are indeed in 
the same series/study.

I believe you can use something as simple as itk::ExtractImageFilter.
