hallo everybody
i have one question, i have the Image daten with different slices, for example 
slice 0 to slice 125, each slice has segmentation or without segmentattion, if  
the  slice  has the segmentation then this slice has the pixelvalue  >0,  if 
without the segmentation also, the pixelvalue=0, 
now i have image daten from slice 23 to slice 56 with segmentation, but i want 
only the slice 23 and slice 56 to keep  the segmentation,  the another slices 
use keep segmentation not any more. 
anybody can tell me, how i can set the another image with pixelvalue with 0, 
that means, how i can delete the segmentation from the slice?

now i use this class to extract one sliceImage
ExtractImageFilter::Pointer extractor= ExtractImageFilter::New();
extractor->SetInput( m_Segmentation );
extractor->SetSliceDimension( sliceDimension );
extractor->SetSliceIndex( Index );
extractor->SetTimeStep( timeStep );
extractor->Update();
SliceImage = extractor->GetOutput();
