Planning and evaluation of reorienting osteotomies of the proximal femur in cases of Slipped Capital Femoral Epiphysis (SCFE) using virtual three-dimensional  models. 3D measurement of the slippage, planning and evaluation of reorienting osteotomies and simulation of the hip motion after simulating osteotomy. (Jens A. Richolt, Matthias Teschner, Peter Everett, Bernd Girod, Michael B. Millis, Ron Kikinis)

A novel technique to measure the pathoanatomical malalignment in cases of Flatfoot Secondary to Posterior Tibial Tendon Insufficiency. Three-dimensional determination of the translation and rotation of an unilateral flatfoot in comparison to the contralateral healthy foot. (Jens Kordelle, Jens A. Richolt, Simon Warfield, Christopher P. Chiodo, John Carrino, Michael G. Wilson, Ron Kikinis)

Development of the acetabulum in case of Slipped Capital Femoral Epiphysis. An anatomical study based on virtual three-dimensional models to demonstrate the pathological changes of the acetabulum in case of SCFE. (Jens Kordelle, Jens A. Richolt, Michael B. Millis, Ron Kikinis)

Automatic Segmentation of MRI of the Knee. A new method of determining the volume and thickness of cartilage of the knee from MRI (Simon Warfield, Carl Winalski, Ferenc Jolesz and Ron Kikinis)

Tensor Controlled Local Structure Enhancement of CT Images for Bone Segmentation. A novel techniques to improve the segmentation of bone structures from Computed Tomography (CT) data. (C-F. Westin, S. Warfield, A. Bhalerao, L. Mui, J. Richolt, and R. Kikinis)

Computer-Assisted Quantification of Periaxial Bone Rotation from X-Ray Computed Tomography. A new computer-assisted method that segments a bone from X-ray computed tomograms (CT), graphically unwraps the bone around its long axis into a surface plot (signature landscape), and measures periaxial bone rotation as translation shift of the landscape. (Jeffrey Tsao, Christopher P. Chiodo, Daniel S. Williamson, Michael G. Wilson, Ron Kikinis)

Anatomy Browser of the Knee. An interactive teaching tool for learning anatomy of the human knee. (Jens Richolt, Carl Winalski, Polina Golland, Michael Halle, Shin Nakajima, Scott Martin, Ron Kikinis)
