A system is provided for determining the movement of an interventional device inside a lumen. The interventional device comprises a distal portion inside the lumen and a proximal portion outside the lumen and the system comprises a processor. The processor is configured to receive one or more images from an ultrasound transducer, wherein the images are representative of the lumen with the interventional device inside and input the one or more images into a machine learning algorithm. The machine learning algorithm is trained to learn the relationship between the content of one or more images of an interventional device inside a lumen and the displacement of the distal portion of the interventional device in an elevational direction parallel, or almost parallel, to the direction of movement of the distal portion of the interventional device and output a one dimensional estimated displacement corresponding to the movement of the distal portion of the interventional device in the elevational direction for one or more of the images.
