This template forms the top of a content tree that allows a colon CAD device to describe the results of detection and analysis of colon evidence. This template, together with its subordinate templates, describes both the results for presentation to radiologists and partial product results for consumption by colon CAD devices in subsequent colon CAD reports.
This template defines a Container that contains the CAD results and summaries of the detection and analysis algorithms performed.
The atomic CAD results of Single Image Findings and Composite Features are described in the Colon 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 colon CAD report may produce no (or fewer than anticipated) results. Colon CAD results are constructed bottom-up, starting from Single Image Findings (see TID 4127), associated as Composite Features (see TID 4125).
See the figure entitled “Top Levels of Colon CAD SR Content Tree” in the “Colon CAD” Annex of PS 3.17.
