Patent ID: 8805475

Claim:
A system configured to be utilized with a magnetic resonance imaging system to perform an image-guided interventional medical procedure, the system comprising: a medical device configured to be inserted into a subject to perform a medical procedure; an imaging coil coupled to the medical device and configured to be inserted into the subject during the medical procedure to provide tracking information regarding a position of the medical device within the subject during the medical procedure; a circuit connected to the imaging coil and configured to switch between an energy harvesting configuration and an image data acquisition configuration, the circuit comprising: an energy harvesting path and an imaging data path connected to the imaging coil, wherein the energy harvesting path and the imaging data path are electrically distinct; an energy storage device connected to receive power delivered along the energy harvesting path when the circuit is in the energy harvesting configuration; and an amplifier connected to receive operational power from the energy storage device and receive imaging data signals from the imaging coil over the imaging data path to thereby amplify the imaging data signals when the circuit is in the image data acquisition configuration.
