D/3D registration is a key technol- ogy in image guidance because it fa- cilitates fusion of 2D X-ray images with 3D pre/intraoperative images. Several methods have been presented in literature. Here we describe a pos- sible improvement of image guidance during TACE procedure using 3D ro- tational angiography (3DRA) and 2D X-rays. The idea is to extract the catheter in the 2D X-rays, extract blood vessels in the 3DRA and then fuse 2D/3D using the knowledge that the catheter is inside the blood vessels. TACE procedure
