[Rtk-users] Reconstructed Slice save as tiff

[Cyril Mory]

Hi Amjad,

You can use an ITK extract filter to extract a region that corresponds 
to one of your slices (along the axis you want). The output of the 
extract filter will be 3D, so you will need to cast it into a 2D images 
using an ITK cast filter.
