<h2>Special Instructions</h2>  <p>The Connectathon Central Archive is used to collect images from Evidence Creators in the DIFF profile and make them available to Image Display systems. Alternatively, the Image Display may ask the Evidence Creator to send images directly to the Image Display system or retrieve them from an Image Manager supporting the DIFF profile.. </p>  <h2>Description</h2>  <p>In this test, Evidence Creators in the MR Diffusion Imaging (DIFF) profile create derived images (ADC and Isotropic), and Image Displays render them </p>  <h2>References</h2>  <p>RAD TF-2: 4.18.4.1.2.5 and RAD TF-2: 4.16.4.1.2.2.6 </p>  >  <h2>Evaluation</h2>  <p>On the<strong> Image Display</strong> system, using the derived ADC and ISOTROPIC images from the Evidence Creator:</p>  <p class="style1">(a) The DIFF profile requires that the Image Display be capable of using information from the Dimension Index Values (0020,9157) to display frames from different SOP instances in differnt view ports, and details the following as <em><strong>required</strong></em> functionality on the Image Display: </p>  <ul>    <li>The Image Display shall have the capability to provide at least one row of three or more viewports for the display of frames with different diffusion images for the same In-Stack Position Number (0020,9057).</li>    <li>As a minimum, frames with b-value b=0 and the corresponding Isotropic and ADC frames created for the maximal b-value shall be displayed. Note that the Isotropic and ADC objects have the same Dimension Organization and In-Stack Position Number index as the object containing the original frames.</li>    <li>The Image Display shall have the capability to filter (exclude) frames in the Original object based on the Diffusion b-value index: only frames with Diffusion b-value index 1 (b=0) are presented, other indices are ignored for presentation.</li>    <li>The Image Display shall have the capability to filter (exclude) frames in the Original object based on the Diffusion b-value index: only frames with Diffusion b-value index 1 (b=0) are presented, other indices are ignored for presentation.</li>    <li>In case there are more In-Stack Position Numbers than there are vertical viewports, the Image Display shall have the capability of synchronized scrolling through corresponding Stack ID / In-Stack Position Number.</li>  </ul>  <p>(b) <strong>Verify annotation: </strong> </p>  <p>The <strong>Image Display</strong> will demonstrate that it is able to display the value, per frame, the values of all attributes in the Dimension Index Pointer (0020,9165):</p>  <ul>    <li>Value of Attribute <strong>(0020,9056</strong>) within the Frame Content Sequence (0020,9111), if indexed by frameStack ID, or</li>    <li>Value of Attribute <strong>(0020,9057) </strong>within the Frame Content Sequence (0020,9111), if indexed by InStackPosition Number, or</li>    <li>Value of Attribute (<strong>0018,9057)</strong>, if indexed by Diffusion b-value </li>  </ul>  <p>The <strong>Image Display </strong>will also display slice offset in mm and frame number. </p>
