CATHETER BEING USABLE IN A MAGNETIC RESONANCE IMAGING SYSTEM

摘要

The present invention relates toa catheter (2) for applying energy to an object (6) and a magnetic resonance imaging system (1) for localizing the catheter (2). The catheter (2) comprises an energyapplication element for applying energy to the object (6), and a cavity for providing a magnetic resonance fluid from which magnetic resonance signals generated by the magnetic resonance imaging system (1) arereceivable, wherein the cavity is adapted for providing a cooling fluid as the magnetic resonance fluidfor cooling the energy application element. The catheter (2) comprises further a tracking coil (15) for tracking the catheter (2), wherein the trackingcoil (15) is adapted to receive the magnetic resonance signals from the magnetic resonance fluid. Thus, the magnetic resonance fluid fulfils at least twofunctions, providing magnetic resonance signals for tracking the catheter (2) and cooling the energy application element.
