摘要
An MR marker (501, 601, 803, 902) for magnetic resonance imaging (MRI) guided intervention and method of fabricating same. The tracking device can be integrated with an MRI-guided robotic system to provide precise positional tracking of the interventional tools and robotic components, allowing safe operation inside the human body. The MR tracking device includes a plurality of stacked flexible printed circuit boards; a plurality of flat planar spirals comprised of a non-ferromagnetic material and directly disposed on a top surface and a bottom surface side of each flexible printed circuit board, a biocompatible, non-ferromagnetic material encapsulating the flexible printed circuit boards; and an adhesive bonding the flexible printed circuit boards. In another aspect, an orientation-independent device is provided including three or more markers (501, 601, 803, 902) in an array around a cylindrical substrate.
