Figure 7From: Accuracy assessment of Tri-plane B-mode ultrasound for non-invasive 3D kinematic analysis of knee joints Experiment 2 (collagen-water solution is used as a coupling medium between US and bone phantom): measurement errors for the proposed system. Graphs (a), (c) are for femur translation and rotation error estimation, and (b), (d) for tibia translation and rotation, respectively.Back to article page
