title: Parse DICOMDIR to get image filepaths
body: <p>I'm trying to locate DICOM filepaths by parsing a DICOMDIR.</p>
  
  <p>But can't seem to figure out how to locate them. I parse through the DICOMDIR as follows:</p>
  
  <pre><code>DicomDirectory dir = new DicomDirectory("AE_TITLE");
  dir.Load(dirPath);
  foreach(DirectoryRecordSequenceItem elem in dir.RootDirectoryRecordCollection){//study
      foreach(DirectoryRecordSequenceItem innerElem in elem.LowerLevelDirectoryRecordCollection){//sequence
          foreach(DirectoryRecordSequenceItem inner2Elem in innerElem.LowerLevelDirectoryRecordCollection){//series
              foreach (DirectoryRecordSequenceItem inner3Elem in lastElem.LowerLevelDirectoryRecordCollection) // img
              {
  
              } 
          }
      }
  }
  </code></pre>
  
  <p>this loops through the each <code>study/sequence/series/image</code> but non of these seem to contain a filepath to a <code>.dcm</code> file.</p>
  
  <p>P.S. I use the ClearCanvas library to create the DicomDirectory object</p>
