Voltage standing wave suppression for MR-guided therapeutic interventions
Abstract:
A system and method of tracking a medical device and generating an image of a target area. The medical device includes a tracking device to create an imaging field-of-view that extends beyond the tip of the medical device while allowing the tip of the medical device to be visualized. The medical device further includes an imaging/visualization device to create an imaging field from the point of view of the medical device. A voltage standing wave suppression device is formed on the exterior surface of the medical device to prevent the formation of voltage standing waves and localized tissue heating. The voltage standing wave suppression device includes two cable traps spaced apart from one another with each cable trap being formed of a closely packed coiled region of a conductor extending the length of the medical device.
