Within this discipline all necessary procedures for calibrating photon and electron beams of high energies (1-50 MeV), as well as X-ray beams of low energy (30-100 keV) and medium energy (100-400 keV) for distant radiotherapy and contact radiotherapy based on international protocols (TRS-398, TG-51, TG-25, TG-61, TG-43) are given. Determination of absorbed dose in water for beams of different qualities, as well as determination of their depth characteristics (distribution of the percentage deep dose, determination of beam energy) and transverse distributions (beam profile, estimation of the flatness and symmetry of the beam, beam output factors) is studied. Measurement of beam characteristics in water (Blue Phantom (IBA)) and solid state phantom (SP34 (IBA)) using ionization chambers (cylindrical and plane-parallel) at therapeutic facilities (Theratron Equinox 100, Multisource HDR, Xstrahl 300, Elekta Synergy (Tomsk Regional Oncology Center)).

The discipline describes the main approaches in the planning of radiation therapy, ranging from topometric preparation of the patient in a computer tomograph (magnetic resonance tomograph) to the immediate placement of the patient on the therapy table and the reproduction of the radiation dosimetry plan. Outlining the necessary volumes of target irradiation and organs at risk, adequate prescription of the tumor dose at the point of interest under different fractionation regimens using the radiobiological linear-quadratic model and for various irradiation techniques, such as conventional radiotherapy, conformal radiation therapy (3DCRT), radiotherapy with transverse (IMRT) and VMAT modulation according to international protocols (ICRU 38, ICRU 50, ICRU 58, ICRU 62, ICRU 71, ICRU 83) are studied. Skills in dosimetry planning by the methods of conventional radiation therapy, conformal radiation therapy (3DCRT), radiotherapy with transverse (IMRT) and volumetric (VMAT) modulation are carried out in the PLUNC, XIO, and Monaco treatment planning systems.

Basic procedures for Quality Assurance of radiotherapy that include periodic inspection of therapeutic apparatus (gamma apparatuses, linear particle accelerators, X-ray tubes), treatment planning systems, and verification of individual irradiation plans in the case of using a transverse (IMRT) and volume ( VMAT) modulation according to international protocols (ESTRO Booklet 7-9, TRS 430, TG-45, TG-142, TG-106, TG-120, TG-119, TG-244) are also included.
