Completed CT scan of the concretion, showing a clenched bronze nail possibly driven through a treenail, joining two sections of wood.

With the kind assistance of the staff of St. Joseph Regional Medical Center and CT (computed tomographic) technologies, we have conducted important pre-conservation analysis of artifacts.

CT Scan

Using these scans, we are able to thoroughly view complex artifacts. Data obtained from scans can then be converted into a variety of CAD formats that are utilized at the Wilder Lab for analysis, rapid prototype replications and for animated modeling videos. 

Using sophisticated computer programs, conservators are able to assess the state of delicate artifacts before attempts are made to excavate them from surrounding concretions. In some cases, removal of concretion and other extraneous data can be conducted on screen, using programmable density mapping techniques. By conducting virtual excavations of fragile material culture, stereo lithographic reproductions of artifacts can be made. These replications serve as 3-D models for excavation difficult artifacts and in some cases, are all that remain when some materials are lost. 

 

Currently, we are working to develop an integrated system, using CT and Vivid 910 scanning data to produce better-fitting and cost effective prosthetic devices.
