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. The reconstruction controller (44) generates an acceptability indicator that may be visualizing or audibly communicated via a user interface (48).

Abstract: An electromagnetic field quality assurance system employing an electromagnetic field generator (10) for emitting an electromagnetic field (12), and one or more quality assurance electromagnetic sensors (11, 21, 31, 41, 50) for sensing the emission of the electromagnetic field (12). The system further employs a quality assurance controller (74) for assessing a tracking quality of the electromagnetic field (12) derived from a monitoring of a sensed position of each quality assurance electromagnetic sensor (11, 21, 31, 41, 50) within a field-of-view of the electromagnetic field (12). The electromagnetic field generator (10), an ultrasound probe (20), an ultrasound stepper (30) and/or a patient table (40) may be equipped with the quality assurance electromagnetic sensor(s) (11, 21, 31, 41, 50).
