## Chest CAD SR IOD Templates

The templates that comprise the Chest CAD SR IOD are interconnected as in Figure A-9.

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 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 chest CAD results.

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 .

Content Item Descriptions

Image Library | The "Image Library" section of the Content Tree (TID 4100 “Chest CAD Document Root”, row 3) may 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 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.
Detections Performed | 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.

### TID 4101 Chest CAD Findings Summary

The contents of this template describe the findings and aggregate features that the chest CAD device detected for the chest evidence presented. This template forms the chest CAD results sub-tree of the Chest CAD Document Root (TID 4100 “Chest CAD Document Root”). The data from which the details are inferred are expressed in the Composite Features (see TID 4102 “Chest CAD Composite Feature”) and/or Single Image Findings (see TID 4104 “Chest CAD Single Image Finding”), of which there may be several.

The sub-tree headed by this template is illustrated in Figure F.1-2 “Example of CAD Processing and Findings Summary Sub-Tree of Chest CAD SR Content Tree” in PS3.17 .

Content Item Descriptions

CAD Processing and Findings Summary | This code value is used to express if and why the Chest CAD Findings Summary sub-tree is empty. The Summary of Detections and Summary of Analyses sub-trees of the Document Root node contain detail about which (if any) algorithms succeeded or failed. If the code value indicates that there were no findings, then the code value can be used to determine whether chest CAD processing occurred successfully, without parsing the Summary of Detections and Summary of Analyses sub-trees.

### TID 4102 Chest CAD Composite Feature

This template collects a composite feature for a lesion, anatomy, non-lesion object, or correlation of related objects (see TID 4101 “Chest CAD Findings Summary”). The details of the composition are expressed in the Chest CAD Composite Feature Body (see TID 4103 “Chest CAD Composite Feature Body”). The data from which the details are inferred, are expressed in the Composite Features (see TID 4102 “Chest CAD Composite Feature”) and/or Single Image Findings (see TID 4104 “Chest CAD Single Image Finding”), of which there may be several.

A Composite Feature shall be INFERRED FROM any combination of two or more Composite Features or Single Image Findings or mixture thereof.

Tracking Identifier | A human readable identifier for longitudinal tracking, e.g., "Watchlist Nodule 1".
Tracking Unique Identifier | This is distinct from the Observation UID (0040,A171) that may be present in the data set for each content item, which identifies only a specific observation, not an object tracked over time, and each tracked object may have many observations.
