<H3>Special Instructions</H3> A clinical expert will evaluate this test.  The representative of the Print Server system is responsible for arranging a time for him/her to do the evaluation with you. <H3>Description</H3> In general, Print Composers should submit print requests that demonstrate the entire range of capabilities/options available on your system.  A wide variety of print requests will improve the interoperability testing with Print Servers.  Consider the criteria in the Evaluation section when selecting samples to print. <p>The Connectathon CENTRAL_ARCHIVE is the source for Mammography studies. </p> <H3>Evaluation</H3> Connectathon Monitors will examine the printed images, checking the following criteria: <p> (1) The Print Composers will demonstrate that it: <ul> <li>E67: does 12-bit printing <li>E68: justifies the images such that the chest wall is printed as close to the edge of the film as the Print Server is capable. <li>E69: can burn into the pixel data these <b>identification and clinical annotations</b> defined for Image Displays: <ul> <li>Patient's Name			 <li>Patient ID			  <li>Patient's Birth Date 		 <li>Patient's Age			 <li>Acquisition Date			  <li>Acquisition Time			 <li>Operators' Name (this may be name or initials) <li>Institution Name 	 <li>Station Name			 <li>Gantry ID (not req'd for Apr 08 EU Connectathon) </ul> <li>E70: can burn into the pixel data the <b>Institution Address</b> (0008,0081) <li>E71: can burn into the pixel data these <b>Technical Factor</b> annotations: <ul> <li>KVP				 <li>Exposure				 <li>Exposure Time	 <li>Filter Material		 <li>Anode Target Material		 <li>Compression Force			 <li>Body Part Thickness			 <li>Positioner Primary Angle	 <li>Relative X-ray Exposure	 <li>Entrance Dose in mGy	 <li>Organ Dose	 </ul> <li>E72: can burn into the pixel data <b>annotation of View Information</b> derived from Image Laterality (0020,0062), View Code Sequence (0054,0220) and any values of View Modifier Code Sequence (0054,0222) items that are present.  The specific abbreviations match the format required for Image Display actors. <li>E73: can burn into the pixel data <b>a ruler, caliper or other form of distance scale</b> <li>E74: can burn into the pixel data aVOI LUT transformation (linear, sigmoid or tabular) <i>as selected by the user</i> from those available in the original image <i>or as otherwise provided by the user</i> </ul> <p> E75: (2) The Connectathon Monitor will verify that the Print Composer sends the Maximum Density attribute (2010,0130) in the print request. </p> <p> (3) The Print Server will demonstrate that it: </p> <ul> <li>E76: does 12-bit printing <li>E77: prints on transmissive media <li>E78: is capable of true size printing  <p><i>(Note the following from RAD TF-2: 4.23.4.8:  "...true size printing(is) based on the Requested Image Size (2020,0030) and shall attain the requested size with a precision of a maximum 2% error in linear distance (this precision requirement is chosen based not any implied or required accuracy of measurements from film or projection radiography, but rather because current electrical, mechanical and optical technology readily allows for this precision, and deviation beyond this value indicates a fundamental flaw in the implementation of the protocol or logic)"</i></p> <li>E79: can print with a border between the chest wall edge of the digital mammography image and the physical edge of the film no greater than 5mm, so that the printed films can be hung on a light box with the chest wall edges of corresponding views directly abutted.  <li>E80: can apply the Maximum Density attribute (2010,0130) received in the print request, and prints with a maximum optical density no less than 3.5 <li>E81: can use a Presentation LUT Shape (2050,0020) value of either "IDENTITY" or "LIN OD" and the Presentation LUT Sequence (2050,0010) <p><i>"LIN OD" and the Presentation LUT Sequence (2050,0010) (Note the following from RAD TF-2: 4.23.4.8:  "... support for a Presentation LUT Shape value of "LIN OD" by Print Servers is specified for Mammography since the expected transmitted illumination of mammography view boxes on which printed film may be hung exceeds the range of illumination for which the Barten model is defined, and hence it may be difficult to achieve consistency between prints, and between prints and displays. It allows the Print Composer to use "LIN OD" to have greater control over the optical density of the printed film, and to take what action is necessary to result in consistency of appearance for the anticipated viewing conditions.")</p></i> </ul> <ul>
