title: [Depth therapy with electrons in the thoracic region. V. Dosimetric studies with telecentric small-angle pendulous irradiation (author's transl)].
abstract: The conditions of dose distribution in telecentric small-angle pendulous electron irradiation of the thoracic region are reported on the basis of isodoses experimentally found using a phantom. Electron energies from 20 to 42 MeV were used, the axial depth amounted to 20 to 30 cm, the pendulous angles to 30 degrees, 40 degrees, or 60 degrees and the field breadth was 3 or 4 cm. Irradiations were performed monaxially as well as biaxially. The influences of single variables upon the dose distribution and especially on the radiation load to skin, lung and spinal cord are discussed.
