Navy Medicine Partners With FBI, Explores 
Craniofacial Reconstruction 


By Capt. Gerald Grant, director of the Craniofacial Imaging Research Group, Naval 
Postgraduate Dental School, directorate of Navy Medicine Manpower Personnel Training 
and Education Command and service chief of 3-D Medical Application Center, Bethesda, 

My team and 1 are currently involved in 
some unique craniofacial reconstruction 
projects and we're partnering with the FBI 
to do it. We are developing a process where 
digital images of the skull and the complete 
head are captured during dental in- 
processing of service member recruits. 

Navy Medicine is a global healthcare network of 
63,000 Navy medical personnel around the world 
who provide high quality health care to more than 
one million eligible beneficiaries. Navy Medicine 
personnel deploy with Sailors and Marines 
worldwide, providing critical mission support 
aboard ship, in the air, under the sea and on the 

The process will provide a digital template 
for craniofacial reconstruction to be used if necessary in the event of combat trauma. 1 have 
found that the use of digital 3-D images to produce cranial implants for our wounded 
warriors has reduced the fabrication and surgical time by more than half. By taking images 
at the time of entry into service, we are able to use the original images of personnel to 
improve our reconstructions, minimize operating room (OR) time, and create better 

outcomes. Navy Medicine Social Media

Images are computed from CT scans, MRIs, Cone Beam CT scans and a host of other data 
sources. We take those images and produce a "virtual 3- D model," which we can register with ^^jff^Tfjf!^ J oin us on Facebook 
other models, remove parts and develop a surgical plan. This is cutting edge medical/ dental 

research. The data we capture involves both skeletal and surface capture of the head and lOj '^^^^ Read our publications 
presently there are only a few small databases with that type of information. Our database 

will potentially be the largest and most diverse database of craniofacial images in the world r ■ - ■ t r- i a. a.

The FBI needs a way to identify thousands of human skeletal remains that they have 
throughout the United States. As such, they have developed a couple of protocols where a 
craniofacial database would be of great use.

I am currently working on an identification program called ReFace for them. I have a limited March 20 15 (5) 

number of Head CT scan images that represent Caucasian, black, and Asian men and women. 

We can place a CT scan of a skull into the program and it will do a reconstruction of the face February 20 15 ( 16) 
from the data it contains. 1 have developed an obj ective measure to validate their software so j an^ajy 20 15 ( 12) 

we can see how accurate it is and 1 am continuing to work with the FBI and software

developers to increase the accuracy and add more data. 

This data can be used to develop a system where we can reconstruct cranial defects for 
fabrication as well. It is pretty cool when all the data looks back at you in the form of a face 
and that's where the FBI wants to identify the face and link it to a real person. 

Although the FBI studies are more directed toward forensic identification, the software works 
to provide reconstruction information as well, which is more in tune with what we want to 
study for the Navy. Either way, by leveraging the skills and resources of both of our 
organizations, we are developing a process that will benefits multiple parties, especially our 
wounded warriors who have sacrificed so much already. 1 am proud to be a part of this 
program and look forward to continue my work on this critical project.
