Создание модели фотонного пучка терапевтического линейного ускорителя ELEKTA Synergy в системе планирования PLUNC

Abstract

In the present study, we performed a comparison and selection of the most appropriate treatment plan with an educational treatment planning system PLUNC which was provide recommended absorbed dose of ionizing radiation in tumor volume, and the minimum value of the dose in organs at risk and normal tissues surrounding the tumor. For this reason, was created model of the photon beam for ELEKTA Synergy Linear Accelerator. The treatment plan was developed for patients with rectal cancer. The simulation was performed on the basis of actual dicom - images of the tumor, which was obtained with modern medical equipment (computed tomography Aquilion Toshiba). For checking of the simulated plan quality, reference dose and dose rate measurements were performed. Present study demonstrates the relationship between the dose distributions and selected treatment plan. As result of research, was conducted comparison and analysis of algorithms for dose calculation in tissueequivalent environment with a treatment planning system PLUNC. Was developed methodological guide for work in the PLUNC software. Thereby, educational treatment planning system PLUNC was put into operation.
