摘要
An invasive device having an inductive coupling element. One embodiment of the invasive device includes a plurality of receive coils inductively coupled to a communicating coil. The receive coils are selectively tuned and detuned to receive MR signals for providing coordinate information used for device tracking. A second embodiment of the invasive device includes a receive coil having a plurality of winding elements separated from each other by different distances. A method of rapidly acquiring both the invasive device orientation and position information to dynamically adapt MR scan planes to continuously follow the invasive device relative to a target is provided. The target-navigation technique automatically defines the MR scan plane and a time domain multiplexing technique is applied for MR imaging and device tracking. Using these techniques, the acquired MR images shows both the invasive device and the target tissue.
