| description | 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. |
