SS.3.3 Example 3: Colon Polyp Detection, Temporal Differencing With Findings​

The patient in Example 2 returns for another colon radiograph. A more comprehensive colon CAD device processes the current colon​ radiograph, and analyses are performed that determine some temporally related content items for Composite Features. Portions of​ the prior colon CAD report (Example 2) are incorporated into this report. In the current colon radiograph the colon polyp has increased​ in size.​
