The answer of you question is OK. vtkTIFFReader can read series images (which
compose 3D image ) with setting as show bellow:

tiffReader->SetFileDimensionality(2);
tiffReader->SetFileNameSliceSpacing(1); 
tiffReader->SetDataExtent(0, 511, 0, 511, 0, 100);
tiffReader->SetFilePrefix("D:\\slice_");  // FilePrefix composes of
directory(e.g. D:\\) and file name prefix(e.g. slice_)
tiffReader->SetFilePattern("%s%d.png"); // %s will be filled with
FilePrefix, %d will be filled with DataExtent's Z range. 

tiffReader->SetDataSpacing (1, 1, 1); 
tiffReader->SetDataOrigin(0.0, 0.0, 0.0);
