XR Catheter Tracking Enhances Cardiac Intervention Efficiency
A novel Extended Reality (XR) platform has been introduced to facilitate real-time tracking of catheters with six degrees of freedom (6-DOF), aiming to improve efficiency, accuracy, and depth perception during cardiac procedures. This system integrates a tailored machine-vision algorithm for five degrees of freedom (5-DOF) tracking alongside a 3D-printed electromechanical encoder for measuring roll, enabling full 6-DOF motion reconstruction within a patient-specific 3D heart model. In a proof-of-concept trial, 20 inexperienced medical students maneuvered an intracardiac echocardiography (ICE) catheter to six targets using either immersive 3D visualization or a 2D display. The 3D group finished in 54.6 seconds, while the 2D group required 267.5 seconds, underscoring XR's potential to enhance procedural results. This research was published on arXiv (2608.07606).
