// .NAME vtkGDCMMedicalImageProperties - some medical image properties.
// .SECTION Description
// vtkGDCMMedicalImageProperties is a helper class that can be used by medical
// image readers and applications to encapsulate medical image/acquisition
// properties. Later on, this should probably be extended to add
// any user-defined property.
