The Templates that comprise the Mammography CAD SR IOD are interconnected as in Figure A-8:
In Figure A-8, '···' indicates possible recursive application of subordinate Templates.
This Template forms the top of a Content Tree that allows a mammography CAD device to describe the results of detection and analysis of Mammographic evidence. This Template, together with its subordinate Templates, describes both the results for presentation to radiologists and partial product results for consumption by mammography CAD devices in subsequent mammography CAD reports.
This Template defines a Container that contains an Image Library, the mammography CAD results, and summaries of the detection and analysis algorithms 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 mammography CAD results.
The Summary of Detections and Summary of Analyses sub-trees gather lists of algorithms attempted, grouped by success/failure status. Algorithms not attempted are not mentioned in these sub-trees. This information forms the basis for understanding why a mammography CAD report may produce no (or fewer than anticipated) results. Mammography CAD results are constructed bottom-up, starting from Single Image Findings (see TID 4006 “Mammography CAD Single Image Finding”), associated as Composite Features (see TID 4004 “Mammography CAD Composite Feature”), and from which Individual and Overall Impressions are formed.

The "Image Library" section of the Content Tree (TID 4000 “Mammography CAD Document Root”, Row 3) shall include all Image SOP Instances from the Current Requested Procedure Evidence Sequence (0040,A375) Attribute of the SR Document General Module. If a portion of another instance of a Mammography CAD SR IOD is duplicated in the "Overall Impression/ Recommendation" section of the Content Tree, the "Image Library" shall also include all Image Library Entries referenced from the duplicated portions of the Mammography CAD SR. |

The "Detections Performed" and "Analyses Performed" sections of the Content Tree together shall reference all Image SOP Instances included in the Current Requested Procedure Evidence Sequence (0040,A375) Attribute of the SR Document General Module. |
