<H3>Special Instructions</H3>  Acquisition Modality and Evidence Creator actors in the DIFF profile perform ONE instance of this test.  <b>This should be done on the first day of the Connectathon.</b>  <H3>Description</H3>  <p>  All Acquisition Modalities and Evidence Creator actors store at least one representative DICOM sample to the Connectathon CENTRAL_ARCHIVE. This will enable Image Manager and Image Display actors to access these objects for their testing.   </p>  <p>You must enter a description of your study in the <em><a href=system_con_object.php?selected=create_object>Objects Information</a></em>.  Please upload there a screen capture of the object so that we can use it for comparison when your peers will render your images.</p>  <b>  Modalities and ECs could also find time to test directly sending their images to Image Manager actors.   </b>  <H3>Evaluation</H3>  <p>In order to validate the test, the connectathon monitor will check:</p>  <ul>  <li>that the objects are stored on the Central Archive,</li>  <li>that there is a corresponding entry in the <em><a href=system_con_object.php?selected=create_object>Objects Information</a></em>  section of the kudu webtool, and </li>  <li>that there is a screen capture of the objects uploaded in the <em><a href=system_con_object.php?selected=create_object>Objects Information</a></em> section of the kudu webtool, and</li>  <li>that the printed output adequately describes the displayed image.</li>  </ul>  <p>Note that samples stored to the Central Archive are checked by a DICOM validator.</p>
