SYSTEMS AND METHODS FOR REGISTERING ELONGATE DEVICES TO THREE DIMENSIONAL IMAGES IN IMAGE-GUIDED PROCEDURES

摘要

Methods for using registered real-time images and prior-time anatomic images during an image-guided procedure are provided herein. An exemplary method includes obtaining a three-dimensional image of a patient anatomy and a portion of a medical instrument disposed therein. The three-dimensional image includes image information characterizing a shape of the portion of the medical instrument. A processing device segments the portion of the medical instrument from the three-dimensional image. Shape data is obtained from the portion of the medical instrument while the portion is positioned within the patient anatomy, and the processing device registers the segmented shape of the portion of the medical instrument with the shape data from the portion of the medical instrument.
