[Optimal conditions for irradiating central cancer of the lung using high-energy photon beams].

The authors describe optimum plans of irradiation of central lung cancer of patients with different stature in a restricted number of radiation directions and without such restrictions. The recommendations obtained are compared with routine methods of irradiation. The description of a single dose field by transformed curves of axial distribution, taking into account the heterogeneity of a medium, are used in computation.
