    摘要： An active tracking system that overcomes the heating problems of conventional transmission line and signal line conductors is provided. The active tracking system includes at least one active tracking coil; at least one integrated circuit proximate the active tracking coil; a tracking receiver; a first MR safe means configured for transmitting a received signal to the tracking receiver; and a second MR safe means configured for communicating one or more signals from the tracking receiver to the integrated circuit at coil. The integrated circuit may also include frequency estimations, analog to digital conversion at the tracking coil location to reduce the amount of processing required in the tracking receiver thereby decreasing the potential for signals passing from the tracking coil location to the tracking receiver to interfere with MR imaging signals.

    摘要： A method for projecting a broad tracking signal received by an inductively coupled element, such as a transformer during an MR tracking sequence is provided. By varying projection planes, the signal acquired from the transformer along the transmission line can be used to depict the body of the actively tracked medical device, such as the shaft or deflection region of a catheter. This may be achieved by interpolating a line between the position of the transformer element within the transmission line and the tracking coil. A curvature may be added to the line segment and gradually increased until the arc length of the line segment is approximately equal to the predefined length. The direction of the curve may be determined by virtually connecting the transformer position to the distal most tracking coil position, then the curve of the line segment is increased towards the proximal coil position.

    摘要： An actively tracked medical device comprising: a dilator having an inner tubular main body having a distal end and a proximal end, said tubular main body including at least first and second receiving channels positioned in a spaced apart relationship on an outer surface of said tubular main body; a region at the distal end of said tubular main body for supporting one or more tracking coils; an atrumatic tip portion operably coupled and positioned distal to said main body; a lumen extending through said tubular main body, said tip support and said atraumatic tip portion; and an outer polymer body having first and second ends, said outer polymer body operably covering said inner tubular main body and said tracking coils, said first end terminating adjacent a proximal end of said atraumatic tip portion and said second end terminating adjacent said hub.
