Abstract

A method is presented to track the guide wire during endovascular interventions and to visualize it in 3D, together with the vasculature of the patient. The guide wire is represented by a 3D spline whose position is optimized using internal and external forces. For the external forces, the 3D spline is projected onto the biplane projection images that are routinely acquired. Feature images are constructed based on the enhancement of line-like structures in the projection images. A threshold is applied to this image such that if the probability of a pixel to be part of the guide wire is sufficiently high this feature image is used, whereas outside this region a distance transform is computed to improve the capture range of the method. In preliminary experiments, it is shown that some of the problems of the 2D tracking which where presented in previous work can successfully be circumvented using the 3D tracking method.
