Automatic registration, centration offers greater accuracy

The automated approach was the fastest overall method of registration. It was three times faster than the fastest manual technician and seven times faster than the most careful technician. We evaluated the delta in terms of each of these five groups of photos from technician to technician and from technician to automated registration, and we found that the difference between the five measurements taken on the same patient was 25% lower with the automated registration than with the best manual technique.
