[Irradiation planning in conservative treatment of cancer of the breast (author's transl)].
Investigations of homogeneous irradiation of the breast with opposed wedge filter fields are presented. Isodose plans calculated with the help of computer programs were compared with measurements of isodose distributions (LiF rods in polystyrol phantoms), and the possibility of optimizing the irradiation method by means of computed plans was examined. Differences between the calculated and the measured values maximally amounted to 10% (programs SIDOS U2 and COMRAD). The calculations correctly describe the place of dose maxima, the homogeneity of the irradiation and tendency to isodose shift caused by variation of the shape of the breast, of the angle of incidence of radiation and of the angles of the wedges. The results are demonstrated using isodose lines in the mediolateral and in the craniocaudal plane of the breast.
