A method is presented to aid the extraction and tracking of guide wires during X-ray fluoroscopy guided endovascular interventions. A two-step procedure is utilized, in which first a rigid translation is determined to capture the rough displacement and next a spline optimization is performed for accurate localization of the guide wire. Both the application of subtraction images and filters which enhance line-like structures are investigated. With the optimal settings, the guide wire was tracked succesfully in 141 out of 146 frames from five sequences.
