F.3 Chest CAD SR Examples

The following is a simple and non-comprehensive illustration of an encoding of the Chest CAD SR IOD for chest computer aided detection results. For brevity, some mandatory content items are not included, such as several acquisition context content items for the images in the Image Library.

F.3.1 Example 1: Lung Nodule Detection With No Findings

A chest CAD device processes a typical screening chest case, i.e., there is one image and no nodule findings. Chest CAD runs lung nodule detection successfully and finds nothing.

The chest radiograph resembles:
