Abstract

Purpose: Describes the features of dosimetric planning for breast cancer and conducts statistics analysis of the radiation treatment planning results, while taking into account 2.5 years of work experience on the Halcyon linear accelerator at the Irkutsk Regional Cancer Center.
 Materials and methods: Varian Halcyon tunnel type linear accelerator and Varian TrueBeam C-arm linear accelerator were used for breast irradiation. Treatment planning was performed in the Eclipse planning system, Acuros dose calculation algorithm. The experience of using the specified equipment and developments in the field of radiation treatment planning using the Halcyon system are presented.
 Results: Developed an approach to planning breast radiation at the Halcyon linear accelerator. A retrospective analysis of 84 radiation treatment plans on linear accelerators of various types was carried out. Breast treatment plans for Halcyon linear accelerator have equal dosimetric parameters in comparison to the TrueBeam treatment plans.
 Conclusion: Linear accelerator Halcyon can be used for treating breast cancer if staff understands specifics of treatment planning and treatment delivery.
