Abstract

In this study, it was aimed to investigate the effect
of different dose rate and different computational resolutions on stereotactic
vertebrae irradiation with the results of the verification schemes on Gamma
analysis and the effect on dose for critical organ and target volume. Ten
patients with vertebrae participated in the study. Patients participating in
the study were investigated for their effect on doses for critical organ and
target volume by recalculating treatment plans at different dose rates and different
computational resolutions without changing the optimization parameters using
Intensity Modulated Radiation Therapy (IMRT) technique in the Eclipse treatment
planning system with Varian Trilogy Linear Accelerator located in Şişli Hamidiye Etfal Training and
Research Hospital ,
Radiation Oncology Department. Verification schedules of all the treatment plans The results
were compared by using the Electronic Portal Imaging Device (EPID). Using
different dose rates did not affect our treatment planning accuracy. However,
it was seen that the high resolution calculated plans represented the target
and critical organ doses better.
