title: [Application of the NSD-concept for the ascertainment of tolerance doses in the region of the lung (author's transl)].
abstract: A clinical application of the NSD-concept using iso-ret plans for the recording of radiation pneumonitis is reported. The conditions of an ascertainment of tolerance values for single organs by help of the Ellis formula are discussed. Of the examined patients with Hodgkin's disease who had been exposed to irradiation of the unaffected mediastinum, 42% suffered from radiogenic lung complications. The calculated iso-ret plans reveal a limitation of the pneumonitic shadow zone identical to the 1200-ret isoline. The data in literature are in accordance with these results.
