Abstract
The present disclosure provides medical devices having MRI-compatible circuitry. Preferably, the devices do not project an enlarged profile, yet their position can be determined during an iMRI procedure. Illustrative embodiments of such a device can include a base surface, a first conducting layer disposed on the base surface, a first insulating layer disposed over at least a portion of the first conducting layer, and a second conducting layer disposed over at least a portion of the first insulating layer.
Claims15
An interventional magnetic resonance imaging (iMRI) device having MRI-compatible circuitry, comprising:
- a base surface;
- a first semi-active magnetic resonance marker formed from a first conducting layer disposed on the base surface to form a resonant circuit, the resonant circuit having a resonant frequency tuned to match the local Larmour frequency corresponding to the background magnetic field B0 of a MRI scanner, wherein the resonant circuit is operable to emit a radio frequency signal responsive to being stimulated by a radio frequency at the resonant frequency.
