St. Jude launches 3D nav system for vascular, cardiac anatomy

St. Jude Medical has launched its MediGuide Technology, a three-dimensional navigation system intended for the evaluation of vascular and cardiac anatomy on a recorded fluoroscopic image instead of live fluoroscopy (a series of x-ray images).

Using magnetic tracking to locate miniature sensors embedded in devices, this technology applies 3D visualization to previously recorded fluoroscopic images, according to the St. Paul, Minn.-based company. Adjustments are made to the recorded images to maintain a real-time clinical representation compensating for cardiac motion, respiratory changes and patient movements.
