The following is a simple and non-comprehensive illustration of an encoding of the Colon CAD SR IOD for colon computer aided detection results. For brevity, some mandatory content items are not included.

SS.3.1 Example 1: Colon Polyp Detection With No Findings

A colon CAD device processes a typical screening colon case, i.e., there are several hundred images and no polyp findings. Colon CAD runs polyp detection successfully and finds nothing.

The colon radiograph resembles:
