Assessment of lung tumor motion and setup uncertainties using implanted fiducials

Purpose: The purpose of this work was to assess the magnitude of setup uncertainties and respiratory-induced motion of lung tumors by monitoring the location of fiducials implanted in the vicinity of the tumors. Methods and Materials: Gold fiducials were implanted in the periphery of lung tumors in...
