Skeletal imaging and Motion Analysis

Unusual movements of the human joint can initiate a degenerative process by changing the mechanical stresses in soft tissues and bone surfaces. We have developed a dual X-ray fluoroscopic imaging system to measure the patient's accurate three-dimensional joint motion. We use this system to understand abnormal joint movements and changes due to surgical intervention.

• Natural skeletal kinematics of the foot and ankle joints during walking

• Foot and ankle kinematics of patients with flatfoot

• Changes of foot kinematics with different shoe types

• Effect of knee arthroplasty design on knee kinematics

• Natural knee kinematics during daily activities

• Mobile robotic X-ray imaging system for dynamic skeletal imaging

• Deep learning-based bone model to X-ray image (3D-to-2D) registration
