Description
The purpose of this study is to evaluate the usefulness of a software-based quality assurance system based on Volumetric M odulated A rc T herapy t reatment p lan. E valuate treatment plan t hrough t he D VH a nalysis, P TV m ean dose (Dmean) and PTV 95% dose(D95) compare the MFX based on original treatment plan, Average error rate was 0.9±0.6%, 1.0±0.8%, respectively. Measuring point dose using phantom and ion chamber, the average error rate between the ionization chamber and MFX was 0.9±0.7%, 1.1±0.7% (high dose region), 1.1±0.9%, 1.2±0.7% (low dose region). The average gamma though of MFX and Delta4PT is 98.7±1.2%, 98.4±1.3%, respectively. Through this study, A software based QA system that simplifies hardware based QA procedures that involve a lot of time and effort. It can be used as a simple and useful tool in clinical practice
