Researchers use Dolphin to compare accuracy of digital superimposition

Chatsworth, CA, January 2010—Dolphin’s Ceph Tracing module in Dolphin Imaging version 10 was used in the study “Comparison of Hand-Traced and Computer-Based Cephalometric Superimpositions,” published in the May 2009 issue of Angle Orthodontist, (Vol. 79, No 3, pp. 428-435).

Recognizing the global trend toward paperless practices and a growing reliance on digital records, the researchers were curious to “…determine the ability of an operator to produce comparable superimpositions using digital (Dolphin Imaging version 10) and hand methods (gold standard) and to determine if a difference existed between the best-fit digital cranial base superimposition and S-N digital superimposition methods.”

The researchers concluded that “This study validates the use of superimpositions produced by Dolphin Imaging version 10 and is a necessary step forward toward widespread acceptance of digital superimpositions.” Further, they determined that: “There are no differences between cranial base and regional superimpositions produced by Dolphin Imaging version 10 and those completed by hand when using the described methods.”
