  • C-arm rotation encoding methods and apparatus
    Patent number: 9008279
    Abstract: This invention provides a method for estimating C-ARM fluoroscope rotation pose, and related programmed media and kits. In one embodiment the method includes measuring an angle of the C-arm using an accelerometer affixed to the C-arm, wherein the accelerometer is not moving during the measurement. The method includes generating angle correction equations based on differences between C-arm poses and corresponding accelerometer angles, and optionally generating structural compensation equations to compensate for structural flexion or deformation of the C-arm.
