In one embodiment a medical tracking system, including a catheter to be inserted into blood vessels of a body-part of a living subject, and including a flexible shaft having a deflectable distal end, and a location tracking transducer in the distal end configured to output a signal indicative of a location of the transducer, a tracking subsystem to track locations of the distal end over time responsively to the signal, a display, and processing circuitry to add the tracked locations of the distal end to a movement log, and render to the display an image of at least part of the body-part with a representation of a length of the shaft of the catheter in at least one blood vessel of the body-part, with respective positions along the length of the shaft being located in the image responsively to respective ones of the tracked locations from the movement log.

A method for displaying guidance information using a graphical user interface during an medical procedure comprises displaying, in a first mode of the graphical user interface, first image data from a perspective corresponding to a distal end of an elongate device. The first image data includes a virtual roadmap. The method also comprises transitioning from the first mode of the graphical user interface to a second mode of the graphical user interface. The transition is based on an occurrence of a triggering condition. The method also comprises displaying, in the second mode of the graphical user interface, second image data from a perspective corresponding to the distal end of the elongate device. The second image data includes a target indicator corresponding to a target location and an alignment indicator corresponding to an expected location of the medical procedure at the target location.

MRI-guided robotics offers possibility for physicians to perform interventions remotely on confined anatomy. While the pathological and physiological changes could be visualized by high-contrast volumetric MRI scan during the procedure, robots promise improved navigation with added dexterity and precision. In cardiac catheterization, however, maneuvering a long catheter (1-2 meters) to the desired location and performing the therapy are still challenging. To meet this challenge, this invention presents an MRI-conditional catheter robotic system that integrates intra-op MRI, MR-based tracking units and enhanced visual guidance with catheter manipulation. This system differs fundamentally from existing master/slave catheter manipulation systems, of which the robotic manipulation is still challenging due to the very limited image guidance. This system provides a means of integrating intra-operative MR imaging and tracking to improve the performance of tele-operated robotic catheterization.

A method includes displaying a position of a distal end of a medical probe that is being navigated in an organ of a patient on a three-dimensional (3D) map of the organ. In response to an event, a plane of interest including the distal end is selected, a real-time Magnetic Resonance Imaging (MRI) slice of the organ is acquired at the selected plane, and the MRI slice is displayed overlaid on the 3D map.
