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.​

- Standard -​

DICOM PS3.16 2020a - Content Mapping Resource​

Page 319​

The atomic CAD results of Single Image Findings and Composite Features are described in the Chest CAD Findings Summary sub-​ tree.​

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​ chest CAD report may produce no (or fewer than anticipated) results. Chest CAD results are constructed bottom-up, starting from​ Single Image Findings (see TID 4104 “Chest CAD Single Image Finding”), associated as Composite Features (see TID 4102 “Chest​ CAD Composite Feature”).​

See Figure F.1-1 “Top Levels of Chest CAD SR Content Tree” in PS3.17.​

If a portion of another instance of a Chest CAD SR IOD​ is duplicated in the "Chest CAD Findings Summary" section of the Content Tree, the "Image Library"​ may also include all Image Library Entries referenced from the duplicated portions of the Chest CAD SR.​

The Image Library is intended to be used in cases where the acquisition context Content Items differ​ from image to image, such as different views and/or laterality in projection X-Ray.​

The "Detections Performed" and "Analyses Performed" sections of the Content Tree (TID 4100 “Chest​ CAD Document Root”, rows 7 and 9) together shall reference all Image SOP Instances included in the​ Current Requested Procedure Evidence Sequence (0040,A375) attribute of the SR Document General​ module.​
