Abstract

The present disclosure relates to a method for detecting a tip of a vascular catheter in a sequence of vessel image frames obtained using x-rays. The method comprises the steps of determining, within the vessel image frames, a proximal point, the proximal point corresponding to a vessel ostium, cropping the sequence of vessel image frames to an image area surrounding the proximal point to generate a cropped sequence of cropped vessel image frames, detecting, within cropped vessel image frames not indicative of a contrast medium, the tip of the vascular catheter, and tracking, within the sequence of vessel image frames, the detected tip of the vascular catheter.
