[A way to spatial irradiation planning. IV. Examples of radiotherapeutic practice and conclusions]

The method described in detail in part III of this paper aims at an optimization of dose distributions with regard to homogeneity within the common area of intersection of the ray beams concerned; now, practical planning is achieved with good results. Common clinical examples are treated, but of such a kind that dose homogeneity is not to be obtained without difficulty, either because of the chosen arrangement of fields within different planes of incidence or on other grounds. Finally, the advantages, practical possibilities and limits of the method indicated are thoroughly discussed.
