Abstract: An intervention system employs an interventional device (10), and a sensor wire (20) manually translatable within a lumen (11). The intervention system further employs a reconstruction controller (44) for reconstructing a shape of the interventional tool (10) responsive to a sensing of a manual translation of the sensor wire (20) within the lumen (11) (e.g., a EM sensor being attached to/embedded within a guide wire), and for determining a reconstruction accuracy of a translation velocity of the sensor wire (20) within the lumen (11) to thereby facilitate an accurate reconstruction of the shape of the interventional tool (10). The reconstruction accuracy may be determined by the reconstruction controller (44) as an acceptable translation velocity being less than an acceptable threshold, an unacceptable translation velocity being greater than an unacceptable threshold, and/or a borderline translation velocity being greater than the acceptable threshold and less than the unacceptable threshold.
