void InitFileNames ( )

protected

Parse through the DICOM images and determine which ones belong to the same series as the specified input file instances (StudyInstanceUID, SeriesInstanceUID), then also verify that each image has the same orientation. The orientation check is useful for cases when there are multiple orientations in the same series (e.g. 3 plane localizer). Since there may be slight diffs between the values in ImageOrientationPatient the check is performed to within a tolerance.

Currently only supports single volume data, i.e. only one image at each location (ImagePositionPatient).
