The dependence of the PTV dose homogeneity expressed as HI (a, b) and PTV dose conformity CN (c, d) on either the isocentre displacement from the patient origin in the transversal plane and the minimal distance between CTV and external contour. 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
