// Probably the most common representation of datasets in clinical
// applications is the one that uses sets of DICOM slices in order to compose
// tridimensional images. This is the case for CT, MRI and PET scanners. It is
// very common therefore for image analysists to have to process volumetric
// images that are stored in the form of a set of DICOM files belonging to a
// common DICOM series.
//
// The following example illustrates how to use ITK functionalities in order
// to read a DICOM series into a volume and then save this volume in another
// file format.
