Fig. 2From: Quantification of three-dimensional soft tissue artifacts in the canine hindlimb during passive stifle motionModel-based tracking method using fluoroscopy. (a) The three-dimensional poses of the femur and tibia/fibula were determined by best matching the digitally reconstructed radiography (DRR, green) and the corresponding fluoroscopic images (gray). (b) The same procedure can be applied to a full sequence of fluoroscopic images to reconstruct the three-dimensional kinematics of the stifle jointBack to article page
