Imaging Technology Group
The primary mission of the Imaging Technology Group (ITG) is to provide state-of-the-art imaging facilities for researchers at the Beckman Institute for Advanced Science and Technology and the University of Illinois at Urbana-Champaign. This service mission is accomplished through two facilities: the Microscopy Suite and the Visualization Laboratory.
A secondary mission of the ITG is to develop advanced imaging technologies with an emphasis on projects in remote instrument control and scientific visualization.
Bone Density Differences Due to Habitual Behavior
October 17, 2006
These images illustrate a method for inferring differences in habitual knee posture from bone density patterns on the joint surfaces of extant and fossil animals. Both images are oblique slices, obtained from CT data, through the medial femoral condyles (knee joints) of sheep that were trained to walk on treadmills of differing slopes. Color maps were applied using AMIRA software (Mercury Computing Systems) to reflect differences in relative density across the joint surfaces. The subject on the left used a flat treadmill and relatively extended knee postures. The subject on the right used an inclined treadmill and more flexed knee postures. The difference in posture is reflected in their bone properties by the different positions and breadths of the regions of maximum density shown in red. The sheep model was used to validate this methodology and this technique has proved useful for inferring habitual posture and locomotor behavior in extinct subfossil lemurid primates and museum specimens of extant primate taxa. We are in the process of applying this method to infer locomotor patterns used by human ancestors. This work is being conducted in the Evolutionary Biomechanics Laboratory in the Department of Anthropology at the University of Illinois.

Travis Ross, visualization laboratory manager at the Beckman Institute, recently performed a 3D scan of the Katharine Sharp Memorial, a bas-relief sculpture of Katharine Lucinda Sharp, university librarian and founding director of the Graduate School of Library and Information Science (1893-1907). The sculpture was created by Lorado Taft and hangs in the Main Library.
The final 3D image was created by stitching together 40 individual scans, each capturing the rich texture of a piece that was originally sculpted in 1921. GSLIS Dean John Unsworth requested the scan, which uses advanced technology to further memorialize a groundbreaking leader, not only of this campus, but in the field of library and information science.
"We're grateful to the Imaging Technology Group and the Library for helping us turn Katharine Sharp into information that can now be shared freely," said Unsworth.

The March 22, 2011 issue of Advanced Functional Materials cover features an image by ITG's Janet Sin-Hanlon. Created for the article "Biosensors: Control of Nanoscale Environment to Improve Stability of Immobilized Proteins on Diamond Surfaces", authored by Adarsh D. Radadia, Courtney J. Stavis, Rogan Carr, Hongjun Zeng, William P. King, John A. Carlisle, Aleksei Aksimentiev, Robert J. Hamers and Rashid Bashir, the image depicts antibodies attached to a diamond surface, improving protein function.
