Abstract

C-arm volume reconstruction has become increasingly popular over the last years. These imaging systems generate 3D data sets for various interventional procedures such as endovascular treatment of aneurysms or orthopedic applications. Due to their open design and mechanical instability, C-arm imaging systems acquire projections along non-ideal scan trajectories. Volume reconstruction from filtered 2D X-ray projections requires a very precise knowledge of the imaging geometry. We show that the 3D image quality of C-arm cone beam imaging devices can be improved by proper design of the calibration phantom.
