We have developed a biplane system in which two X-ray fluoroscopes image the foot during walking. The 2D fluoroscope images are then converted to 3D bone motion using a custom model-based tracking method. Similar methods have been found to track tibia motion with errors less than 1 mm in translation and 1 degree in rotation; however, the small, irregularly-shaped, close-packed bones of the foot are particularly challenging. The goal of this study is to validate our model-based tracking algorithms using bone phantoms.


I will be presenting this study at the International Society of Biomechanics Conference in August, 2019.
