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.
