IMRT Verification, Analysis and Performance Evaluations: Modeling of Dose Delivery by Shifting MLC Angel and Phantom Position

Abstract

In modern radiology treatment workflow, verification is a critical process for determining the validity of specific treatment planning. In this article, we verified a treatment plan by modeling of dose delivery by shifting MLC angel and phantom position. The study result shows that any error during the verification process such as an error in the MLC angle or the phantom positioning may lead to different passing rate and refuse a plan, which it is correct originally.
