摘要
A system and method for tracking or otherwise determining positioning of an intracorporeal device is provided. The invention includes a device that may be inserted into a subject and tracked based on an imageable tag included with the device. The imageable tag is at least partially formed of a substance whose nuclei precess at a Larmor frequency different than the Larmor frequency of hydrogen when subjected to a polarizing magnetic field. MR data may be acquired from the imageable tag using an RF receiver tuned to the Larmor frequency of the substance and used to track movement of the device within the subject.
