摘要

Intensity modulated radiotherapy (IMRT) irradiation technique uses steep dose gradients to protect organs at risk (OAR) during treatment course. Therefore even small mistakes in patient positioning during treatment course may lead to significant changes in dose distribution. The influence of small errors (order of millimeters) in patient's positioning on resulting dose absorbed in OARs and target volume (PTV, GTV) was simulated in this work.
