The dependence of the PTV dose homogeneity expressed as HI (a), PTV dose conformity CN (b), mean dose to the oesophagus (c), V20Gy and V5Gy values for lungs (d, e), and mean dose to the lungs (f) on the target volume sphericity Ψ. All dosimetric parameters were calculated using DCAT treatment plans. An individual patient case is represented as a point in the diagram; its x- and y-coordinates represent its relevant parameter values
