CAD Operating Point​

Additional information to use when Rendering Intent is "Presentation Optional". A CAD Operating Point​

 

of zero is not sent, and is encoded as a Rendering Intent of "Presentation Required". See Section O.2​

 

“Structured Reporting Storage SOP Class SCU and SCP Behavior” in PS3.4 and Section E.4 “CAD​

 

Operating Point” in PS3.17.​

Certainty of Finding​

The certainty of the CAD device that the finding detected and classified by the Single Image Finding​

 

CODE specified is in fact that type of finding.​

Figure A-9b. Colon CAD SR IOD Template Structure​

TID 4120 Colon CAD Document Root​

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 “Colon CAD Single Image Finding”), associated as Composite Features (see TID 4125 “Colon​ CAD Composite Feature”).​

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