title: How do i get value for (0008,0018) SOP Instance UID while sending C_Get request to Dicom server
body: <p>I need to get a file from Dicom server.</p>
  
  <p>But server do not send a valid pixel data unless i give (<code>0008,0018 i.e. SOP instance UID</code>), so if I give this SOP Instance UID (I already have this value from one of successful logs) then it works fine. </p>
  
  <p>I have to no idea how and what value to put in <em>TAG (0008,0018)</em> while retrieving file using <code>C_Get</code>..</p>
