body: <p>How to read raw image data from uncompressed DICOM file and dump it to a file. I just use the following code for compressed files. using dcmtk library</p>
  
  <pre><code>dataSet-&gt;findAndGetElement(DCM_PixelData, element);
  pixDataElem = OFstatic_cast(DcmPixelData*, element);
  
  DcmPixelSequence *pixelSequence = NULL;
  E_TransferSyntax tran_Syntax = EXS_Unknown;
  const DcmRepresentationParameter *representation = NULL;
  
  // Find the key that is needed to access the right representation of the data within DCMTK
  pixDataElem-&gt;getOriginalRepresentationKey(tran_Syntax, representation);
  //pixDataElem-&gt;getCurrentRepresentationKey(tran_Syntax, representation);
  
  // Access original data representation and get result within pixel sequence
  pixDataElem-&gt;getEncapsulatedRepresentation(tran_Syntax, representation, pixelSequence);
  
  
      DcmPixelItem *pixelItem = NULL;
      //Access the First frame by skipping the offset table...
      pixelSequence-&gt;getItem(pixelItem, 1);
  
      Uint8 *pixels = NULL;
      pixDataElem = (DcmPixelData*)pixelItem;
      pixDataElem-&gt;getUint8Array(pixels);
      Uint8 *pixels = NULL;
      pixDataElem-&gt;getUint8Array(pixels);
      //Writing the Raw data to a file...
      FILE *file;
      file = fopen("D:\\DicomImage.jpeg", "wb");
      fwrite(pixels, sizeof(char), imageSize, file);
      cout &lt;&lt; "File write Completed and the File is closed Successfully" &lt;&lt; endl;
  </code></pre>
  
  <p>How can I raw image data from the uncompressed files with many frames in c++ using dcmtk library.....?</p>
