The intended procedure was a localization of a right upper lobe lung nodule.The staff called veran technical support during localization procedure with the patient scanned laterally with pads placed on the back.They were unable to complete automatic registration and therefore had to place the pads on the side and walk through vpad snapshot.When they were trying to collect the lumen points, the physician was stating that he was in the trachea but the points were collecting in the left lobe.They reset the point cloud multiple times and the issue persisted.They tried resetting the snapshot multiple times and collecting point cloud but that did not fix the issue.They attempted to trim the point cloud but they were unable to get a good fit.When looking at the planning data, they noticed that the field of view was cutting off the top sensors on the two main board pads, which is the main reason why they were unable to successfully get through automatic registration.There was a reported 30-minute delay during troubleshooting.Navigation was discontinued and the procedure was completed using ultrasound.Although there was no impact on the patient, this event is being reported due to the 30-minute procedure delay while the patient was under anesthesia.
