[vtkusers] Why vtkDICOMFileSorter only find one series

[David Gobbi]

Hi James,

All of the images in that zip file have the same SeriesInstanceUID.  So
this is, in fact, a single series that contains two stacks. This is fairly
common.

The vtkDICOMReader can be used to find the number of stacks:

  vtkSmartPointer<vtkDICOMReader> reader =
vtkSmartPointer<vtkDICOMReader>::New();
  reader->SetFileNames(sorter->GetFileNamesForSeries(0));
  reader->UpdateInformation();
  vtkStringArray *stacks = reader->GetStackIDs();
  int numberOfStacks = stacks->GetNumberOfValues();

The reader can also be told which stack to read:

  reader->SetDesiredStackID(stacks->GetValue(0));
  reader->Update();

With the "Enhanced MR Image IOD" and the "Enhanced CT Image IOD", it is
even possible for a single _file_ to contain multiple stacks.

 - David
