Lab 3-D scans human skeletal remains dating back to the American Civil War
In the Virtual Curation Laboratory, the lab's director, Bernard Means, Ph.D., is holding a realistic-looking 3-D printed replica of a human skull fragment that was dented by a bomb explosion during the Civil War.
"For the rest of this person's life, they had seizures because of the [injury]," Means said. "In fact, they died because they fell into water during a seizure and they drowned."
Means 3-D scanned the skull fragment during a recent visit to the National Museum of Health and Medicine as part of an agreement with the museum to 3-D scan items, primarily historic bone specimens, from the Civil War through World War I.
The museum, located in Silver Spring, Maryland, was established during the Civil War as the Army Medical Museum, a center for the collection of specimens for research in military medicine and surgery.
VCU's Virtual Curation Laboratory specializes in the 3-D scanning and 3-D printing of historic and archaeological objects, and is part of the School of World Studies in the College of Humanities and Sciences.
So far, Means and his students have scanned and printed replicas of roughly 30 items in the museum's collection.
Among the highlights are a leg bone that healed poorly after being shot during the Civil War, a skull with a hole in it from a Civil War surgeon's trepanation procedure, a mummified ear attached to a skull fragment that was donated in the early 1900s, and a late 19th-century skeletal hand with a bullet hole from an area in the Midwest designated for Native American resettlement. None of the remains being 3-D scanned is Native American.
By 3-D scanning items at the museum, the Virtual Curation Laboratory is aiming to make the collection more accessible to researchers and the public.
"They want to get 3-D scans of items in their collection and they want to get them out there so the public can see them and also so that researchers can access them," Means said.
For public programs, 3-D printed replicas allow visitors such as school groups to get a more hands-on experience with a museum's collection, he said.
"If a school group visits, [the museum] can't pass around human skeletal remains," he said. "But they can pass around 3-D printed replicas."
The collection is of particular interest to researchers focused on the history of battlefield trauma, as well as forensic anthropology.
Terrie Simmons-Ehrhardt, a researcher in the Department of Forensic Science who studies forensic anthropology, specifically in forensic craniofacial identification and 3-D osteology, has been collaborating with Means on 3-D scanning bone specimens with a goal of creating a digital forensic osteology collection that would be accessible to anyone doing forensic research or education.
"I am assisting Bernard with the surface scanning of NMHM osteological specimens and also assisting the museum with processing of micro-CT and CT scans of some specimens," Simmons-Ehrhardt said. "We are generating high-resolution 3-D models to be shared online that can be interacted with either online or in 3-D software, as well as 3-D printed."
