Abstract:
With the rapid development of intensity modulated radiation therapy (IMRT) technique,the accuracy of radiotherapy has improved,while the pretreatment dose verification has become more complex.Although the experimental measurements,a widely used way to perform dose verification,is accurate and effective,its time-consuming and labor-intensive is still a challenge for physicist.The independent dose verification method such as the depth dose-off axis ratios (OAR) empirical model,Clarkson integral model,convolution model and Monte Carlo model,could partially solve these problems effectively when the accuracy is ensured within a certain range.This approach could save physicists' time to conduct dose recalculation and plan check,and has become the hotspot in the world.This paper,therefore,mainly introduces the correction-based and the model-based independent dose verification methods,and briefly discusses the development of dose verification for IMRT plans.
