| Popis: | Purpose: The assessment of the dose load on a pregnant patient during irradiation of the oropharyngeal tumor at different distances from the border of the irradiated field, including at the level corresponding to the position of the fetus, based on phantom measurements.Material and methods: To calculate the exposure plan, the ECLIPSE planning system with the AAA algorithm was used. Irradiation was performed on a LinacClinaciX (Varian, USA) with a nominal photon energy of 6 MeV. The tissue equivalent phantom Alderson–Rando was used to assess the dose load on the fetus.Results and conclusions: It was shown that the total absorbed dose at the level and below the diaphragm (the level of the fetus) at a distance of more than 40 cm from the border of the irradiation field for the entire course of radiation therapy turned out to be significantly less than the permissible limits indicated in the literature and amounted from 41.71 to 14.03 mGy. |
