Motion Tracking from Digitally Reconstructed Radiographs

Themes People Videos Talks Sponsors Publications Bibliography

Status: Active

Tracking accurately in-vivo bone motion for orthopaedic research applications requires the acquisition of a sequence of radiation-based medical images such as 2D X-ray images or 3D computed tomography (CT) volumes. The Digitally-Reconstructed Radiograph (DRR) technique is often used to minimize in vivo radiation exposure while tracking bone motion dynamically. We aim to develop a robust and accurate method for recovering bone motion from sequences of radiographic images.
