Until a software update is available, ensure you are following the instructions below to prevent the issue from occurring: Firm recommends NOT turning off Guidance View after locking the biopsy trajectory in the Cranial software. After locking trajectory for biopsy needle navigation, always ensure Guidance View remains an active view in at least one screen layout quadrant. If a discrepancy is detected between the biopsy depth gauge graphic and the other 2D information: 1) Obstruct the camera field of view of the biopsy needle or reference frame to cause red status. 2) Return to green status by no longer obstructing camera field of view of the biopsy needle and reference frame. 3) Use the Cycle Views icon to refresh guidance view and confirm that the biopsy depth gauge graphic matches the distance to target values and the position to target information provided by the 2D crosshairs. 4) Visually confirm accuracy before proceeding with navigation. Always Visually confirm navigational accuracy and confirm that the biopsy depth gauge graphic matches the distance to target values and matches the position to target information provided by the 2D crosshairs, which represent the tip position of the navigated instrument. Use the Biopsy Needle Mechanical Depth Stop. If system navigation seems inaccurate and steps to restore accuracy are unsuccessful, abort use of the system.
