1. A LINAC mechanical isocenter determination process comprising:
mounting a signal emitter module on a collimator;
mounting a signal receiver module at a location with an unobstructed view of the signal emitter module;
determining an axis of rotation for a gantry by rotating the gantry while the signal receiver module acquires signal emitter module positions;
determining an axis of rotation for the collimator by rotating the collimator while the gantry is at a fixed position and the signal receiver module acquires signal emitter module positions during the collimator rotation; and
determining the LINAC mechanical isocenter by processing signal emitter module positions during the collimator rotation and the gantry rotation.
