For irradiation of neoplasms located near vital radiosensitive structures and organs, it is necessary to ensure precise spatial alignment of the beam with the target in proton therapy sessions. The aim of this work is to compare the dose distributions obtained in the proton beam planning program and measured as a result of an experiment using radiochromic films. In the first stage of measurements, the correspondence of the degree of film darkening to the radiation dose was determined. For this, thirteen pieces of film, with size 20×20 мм, were cut out from one sheet of film, which were then irradiated with doses (0; 0.25; 0.5; up to 3 Gy). A calibration curve was constructed on the basis of these films, and approximation equation was calculated. This equation is used to convert the values of the darkening matrix of the irradiated films to the values of the absorbed dose. Longiudinal and transverse dose fall-off from 80% tо 20% occurs at a depth of 9.2±0.3 мм and a width of 9.0±0.3 мм, respectively.
