Illustration of the planning technique with beam outlines (a) of tangential fields (above) and additional fields for lymph node irradiation (below) and the coordinate system (middle); dose distribution of original treatment plan (b) in planning CT position (above) and for an exemplary 6-DOF shift (x,y,z = -3,-4,1 mm; yaw,pitch,roll = 1,-2,-4°) with obvious target volume coverage reductions (below), and for + 5° (c, above) and − 5° (c, below) rotational shift in roll around isocenter for illustration of the asymmetric effect on the spinal cord maximum dose
