Figure 5: Display of entry-angle mode of pedicle screw trajectory planning. (a) Marking of entry point fiducial (E1). (b) Display of desired trajectory of pedicle screw for the chosen entry (E1) with desired yaw (medial-lateral angle, 20 degrees). (c) Window displaying the control panel for setting the desired screw length, diameter pitch (cranial-caudal), and yaw (medial-lateral) angles
