A Method for Guide Wire Tracking in X-Ray Angiographic Images based on Open Active Contours

In recent years, endovascular interventions have developed rapidly with expected to contribute to improve traditional vascular surgery in the aspects of recovery time and patient safety. Therefore, tracking an accurate position of the guide wire in the coronary artery has become an important area. This paper proposes a guide wire tracking algorithm based on OAC (Open Active Contours). The method focuses on improving the accuracy of guide wires tracking in a single frame and the speed of the extraction of the position of guide wire. In image processing procedures, we integrate a multiscale-filter for vessel's image enhancement, a method of OAC based on edge detection for initializing the vessel's image and an algorithm for deforming and control of curves. A standard analysis is used to evaluate this method in the last part of this paper. And the results show that the accuracy rate is 95.3% from the clinical images.
