Hi Hamid

Can you tell me what you are trying to do with this raw data? The pixel data ($7FE0,$0010) is the image within the DICOM file, so why access it via the tag rather than just using the image that ImageEn returns?

Hi Hamid

It should be something like:

var
  atag: PIEDicomTag;
  aMemStream : TMemoryStream;
begin
  atag := MainForm.ImageEnMView1.MIO.Params[0].DICOM_FindTag($7FE0,$0010);
  if atag = nil then
    raise Exception.create( 'Invalid Tag' );

  aMemStream := TMemoryStream.Create();
  aMemStream.Write( atag^.Data, atag^.DataLen );
  aMemStream.Position := 0;
  // Do something with aMemStream
  aMemStream.Free;
