ABSTRACT:
An integrated system for real-time navigation assist during interventional radiological procedures utilizes a two-dimensional model of a catheter guide wire, obtained by performing image analysis on a fluoroscopic image in realtime, and a three-dimensional model of a patient's vascular system. The system backprojects the two-dimensional model into the three dimensional model and provides a three-dimensional display of the catheter in a patient's vascular system in real-time.
