Abstract
A method and system of correcting alignment of catheter relative to a target including receiving signals from an inertial measurement unit located at a distal end of a catheter, determining movement of the distal end of the catheter caused by physiological forces, receiving images depicting the distal end of the catheter and the target, identifying the distal end of the catheter and the target in the images, determining an orientation of the distal end of the catheter relative to the target and articulating the distal tip of the catheter in response to the detected movement to achieve and maintain an orientation towards the target such that a tool extended from an opening at the distal end of the catheter would intersect the target.
