Volumetric x-ray imaging offers exciting possibilities for multidisciplinary investigations. Davidson College is the first non-governmental entity to possess the Digitome® software, although this software has matured in development and has been applied in significant ways for 30 years. Unlike Computed Tomography (CT), the Digitome® software employs digital tomosynthesis through a series of conventional 2D x-ray images of an object taken from different non-planar perspectives. Using calibration information with regard to geometry and distances, the user can view the image from any direction and easily make measurements with 25-50 micrometer accuracy. The Digitome® user can even detect features obscured by intervening physical features within the object of study. A major benefit is the immediate scrolling through the object along any axis. Because of the small amount of data that is used, scrolling through 2D planes can viewed in near real time with just a typical desktop computer after taking the image, about a 15-minute process. Incorporation of this software into our liberal arts research and teaching program, including topics in archaeology, animal physiology and metrology, will be presented.
