<h3>Special Instructions</h3> <p>The Image Fusion profile does not specify how the images  are obtained by the Evidence Creator.  <br>   Images will be available on the Connectathon  CENTRAL_ARCHIVE after Modalities complete their FUS_MOD_STORE test.<br>  </p> <p>This is a test between Modality and Evidence Creator  actors.  However, part of the evaluation  requires that the result of the fusion performed on the EC be displayed; this,  the Image Display is identified as an 'optional' actor (the Display  functionality is not evaluated in this test, but a Display system is required  to help during the evaluation).</p> <h3>Description </h3> <p>This test case ensures that Evidence Creators can perform  registration and blending on images from various imaging modality systems.<br>   Evidence Creator actor will store the resulting BSPS and  Spatial Registration objects to the Connectathon CENTRAL_ARCHIVE in  FUS_EC_STORE.  Evidence Creator actors  will also directly sending these DICOM objects to Image Manager actors in test  FUS_EC_IM.  Storage Commitment is tested  in that test.</p> <h3>Evaluation</h3> <p>The Connectathon Monitor will ask the <strong>Evidence Creator </strong>to demonstrate in its application:<strong></strong></p> <bl>  <li>E1... that it can register to image datasets which do not  share a Frame of Reference.  It performs  translations, rotation and scaling, as required).   The Evidence Creator demonstrates its  method/algorithms for registration.   (Specific methods are not mandated by the profile.)  <strong></strong></li>   <li>E2... (recommended functionality) that it records the name  and description of the method of registration within the Spatial Registration  object.<strong></strong></li>   <li>E3... it can set the  contrast/window settings for the underlying grayscale dataset<strong></strong></li>   <li>E4... it can set the windowing and color map for the  overlay dataset<strong></strong></li>   <li>E5... it can set the transparency for the overlay dataset<strong></strong></li> <bl>  <p>The Connectathon Monitor will ask the <strong>Evidence Creator </strong>to identify the <strong>Image Display</strong> system which holds the studies the Evidence Creator  used in this test :<strong></strong></p> <bl> <ul>   <li>E6...<u>For each study</u>, the Connectathon Monitor will  view the fused display on the Image Display system.  The Image Display is used to verify that the  registration and blending parameters were encoded properly by the Evidence  Creator.  If the study is not properly  displayed, the Connectathon Monitor may ask the Evidence Creator to show the  contents of the DICOM attributes in the BSPS and Spatial Registration object to  verify that they were properly encoded to help identify the source of the  problem.<strong></strong></li> </ul>
