<h2>Special Instructions</h2> <p>This is a test to demonstrate the Image Display's ability to properly render enhanced MR diffusion images from various Acquisition Modality vendors supporting the MR Diffusion Imaging (DIFF) profile. </p> <p>If the Modality system is also able to create derived frames (ADC or ISOTROPIC images) from the originals, it is also an Evidence Creator in the DIFF profile, and should run test DIFF_EC_ID in parallel with this one. </p> <p>The Image Display should initiate this test and obtain the images. The Image Display may query/retrieve studies from the Central Archive or Image Manager storing studies for the Modality system under test, or it may ask the Modality system to send studies to it directly. </p> <h2>Description</h2> <p>In this test, the Image Display shows its ability to display MR diffusion images according to the requirements in the DIFF Integration Profile. </p> <h2>References</h2> <p>RAD TF-2: 4.16.4.2.2.n </p> <h2>Evaluation</h2> <p>On the<strong> Image Display</strong> system, using the ORIGINAL images from the Modality:</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>
