Popis:	The mathematical and interpretation tasks of a directed shaping of dose fields in the contrast radiation therapy of malignant tumors are defined on the basis of the dose-field homogeneity parameter. A schematic iterative algorithm of how to solve the tasks is described. A method for the visual optimization of such field is elaborated; it is based on preset limits to the dose field in the lesion focus and in the healthy organs and tissues. The dose field is shaped by an applicator with multiple terminal fixed positions of irradiation sources--the effect is achieved due to variability of their exposure duration.
