1. An imaging-based calibration method for a radiation treatment system including a gantry and a treatment couch, the method comprising:
generating gantry-angle dependent isocenter beam deviation information; generating couch rotation-angle dependent couch position offset information; and correcting target position by combining the gantry-angle dependent isocenter beam deviation information with the couch rotation-angle dependent couch position offset information. |
