title: [Computed tomography for individual treatment planning in tumors of the facial bones (author's transl)].
abstract: Moving-field irradiation of malignant tumors in the region of the facial bones makes possible the application of high focal doses along with optimal sparing of radiosensitive organs and is yielding very good cosmetic results. An indispensable condition, however, is a correctly scaled, exact representation of bone structures in the medium plane of pendulum irradiation. Standardized transversal sections of the skull or radiometric techniques mostly do not satisfy, being deficient in precision and demanding too much time. Every pendulum plane desired can be represented in the picture obtained by addition from the series of transversal sections with the help of appropriate programming of the computer for tomography. By means of an objective representation of the osseous skeleton, of cavities, soft tissues, and of the tumor contours, individually optimized irradiation planning is possible.
