  • Publication number: 20160081668
    Abstract: A system and method is provided for solving the AX=XB calibration problem. A calibration method is presented to determine the unknown X in the AX=XB calibration problem. Sensor data is filtered, such that data without the desired screw theory invariants are discarded. The correspondence between A and B is then computed, either through a probabilistic Batch method that treats the data streams as probability density functions, or by formulating the data streams as a time-evolving differential equation which allows for online calibration of the device. Also, a calibration phantom and software is also provided. The phantom is an extension of known Z-fiducial phantoms, in which the Z-fiducials are oriented based on consideration of imaging physics. An additional phantom is designed that does not utilize rods within the phantom to perform the calibration.
