A method to analyze the cord geometrical uncertainties during head and neck radiation therapy using cone beam CT

Abstract We developed a method to analyze quantitatively the residual cord geometrical uncertainties after image registration during head and neck radiation therapy by using sequential cone beam CT (CBCT). The geometrical centroid line of cervical spinal canal was computed to serve as a cord surroga...
