[Insight-users] question ? [Iterators into image series]

[Ariel Hernán Curiale]

Hi agatte, you can use the helper ExtractImageFilter (http://www.itk.org/Doxygen/html/classitk_1_1ExtractImageFilter.html) to extract a particular slide from a volume. You only need to set the start and size properly.


Saludos
