The accuracy of out-of-field dose calculations of a commercial model based algorithm in sliding window inaccuracy for modern technique of patients with prostate cancer
Author(s): Fahimeh Faghihi Moghadam*
Introduction & Objective: The out-of-filed dose can be clinically important as it related to normal tissue irradiation as the aim of the radiation therapy is decrease Normal Tissue Complications (NTCP) while increasing Tumor Control Probability (TCP). Actually radiotherapy treatment planning systems are not commissioned for the out-of-field dose calculations, although the estimation of dose distributions accuracy by TPSs beyond the borders of treatment fields receives less attention. Today’s using modern radiotherapy techniques such as IMRT because of many advantages is most common, while the increase time delivery and also higher number of Monitor Units (MU), results to increase dose outside the fields which can lead to increases potentially risk of secondary cancers after treatment. Based on documents, increase in collimator scatter and head leakage has be.. View More»
