Fig. 3From: Minimally invasive trans-superior articular process percutaneous endoscopic lumbar discectomy with robot assistanceFluoroscopic images are matched with CT data for the planning puncture trajectory. AĀ The robotic system plans the puncture trajectory according to CT scan data is inputed into the working station. B, C, E, F) Anteroposterior and lateral fluoroscopic images are obtained while the robotic arm holds the reference frame. D)The fluoroscopic images are matched with the planning puncture trajectory based on CT dataBack to article page
