  //  This example illustrates how to read a 3D image from a non DICOM file and write it as a series of DICOM slices.
  //  with some changed header information. Header
  //
  //  Please note that modifying the content of a DICOM header is a very risky
  //  operation. The Header contains fundamental information about the patient
  //  and therefore its consistency must be protected from any data corruption.
  //  Before attempting to modify the DICOM headers of your files, you must make
  //  sure that you have a very good reason for doing so, and that you can ensure
  //  that this information change will not result in a lower quality of health
  //  care to be delivered to the patient.
