An interpolation technique to enable accurate three-dimensional joint kinematic analyses using asynchronous biplane fluoroscopy

The notion of registering 3D bone volumes to fluoroscopic images in order to quantify 3D joint kinematics in vivo has been studied for several decades [1]. Biplane fluoroscopy is a highly accurate way to measure 3D joint kinematics, using two common techniques of bead tracking (fluoroscopic radiostereometric analysis (RSA)) or 2D-3D model-based registration [2 –13]. When imaging a moving object, the accuracy of the estimated 3D bone pose using these techniques is very sensitive to the synchronicity of image acquisition between the two planes.
