Figure A-9. Chest CAD SR IOD Template Structure​

In Figure A-9, '···' indicates possible recursive application of subordinate Templates.​

TID 4100 Chest CAD Document Root​

This Template forms the top of a content tree that allows a chest CAD device to describe the results of detection and analysis of chest​ evidence. This Template, together with its subordinate Templates, describes both the results for presentation to radiologists and​ partial product results for consumption by chest CAD devices in subsequent chest CAD reports.​

This Template defines a Container that contains an Image Library, the CAD results, and summaries of the detection and analysis al-​ gorithms performed. The Image Library contains the Image SOP Class and Instance UIDs, and selected attributes for each image​ referenced in either the algorithm summaries or chest CAD results.​
