description: During the work, prostate irradiation planning was performed based on IMRT, 3D-CRT and VMAT irradiation techniques for the same patient using Varian Halcyon and Elekta Compact linear electron accelerators. The use of different planning techniques made it possible to create a uniform dose distribution in the irradiated volume, and in some treatment plans it was possible to reduce the radiation dose to critical organs and achieve clinical goals. Clinical goals are an indicator of the implementation of dosimetric planning. In the case of dosimetric planning of irradiation of the prostate gland in the fractionation mode of 35 fractions of 2 Gy with a total absorbed dose of 70 Gy, the clinical targets are critical organs: small, large intestine, colon, bladder, right and left hip joint, as well as the dorsal and cauda equina. During the qualification work, 14 plans were created, 9 of which were for IMRT and VMAT methods, and the remaining 5 for 3D-CRT. In addition, an analysis of the obtained data was carried out. So, for example, we were able to achieve the best result using the planning method on VMAT, but the optimal choice of irradiation of the prostate gland using IMRT and 3D-CRT is the âBoxâ method, which uses four beams of bremsstrahlung radiation with angles of 0, 90, 180, 270 degrees. The geometry of these beams is almost ideally suited to all the anatomical features of the patient.
