A comparison of several dosimetric parameters (PTV conformity (a), PTV homogeneity (b, c), MU usage (d), dose to the spinal cord (e), oesophagus (f) and lungs, g-i) in both types of treatment plan. An individual patient case is represented as a point in the diagram; its x-coordinate represents the parameter value in the conventional 3D CRT plan, and its y-coordinate represents the parameter value in the DCAT plan. The points shown in gray correspond to cases in which neither treatment plan meets the planning restrictions
