Abstract
A method and apparatus for providing a high-quality representation of a volume having a real-time 3-D reconstruction therein of movement of a catheter, wherein its real-time movement is determined using a lower-quality representation of only a portion of the volume. Movement of the catheter is detected in a 2-D X-ray fluoroscopy image and is reconstructed in a 3-D angiography (X-ray) reconstruction. Described is a catheter design for easier detection, and a technique for 3-D reconstruction of a catheter from real-time 2-D fluoroscopic images and stored 3-D angiography data, so as to present the 3-D reconstructed catheter in the common coordinate frame.
