Small photon field used in the intensity modulated radiotherapy (IMRT) and stereotactic radio surgery (SRS). It is difficult to measure beam profile and output factor because of electron disequilibrium, partial shutting of source because of this challenges, we need the good detector. This article is collection of 5 or more article and summary of the results of EBT3 that compared with EBT2 film ...
Introduction: Beam-angle optimization (BAO) is a computationally intensive problem for a number of reasons. First, the search space of the solutions is huge, requiring enumeration of all possible beam orientation combinations. For example, when choosing 4 angles out of 36 candidate beam angles, C36 = 58905 possible combinations exist. Second, any change in a beam 4 config...
The first purpose of this paper is to shed some new light on the old question of selecting the number of beams in intensity-modulated radiation therapy (IMRT). The second purpose is to illuminate the related issue of discrete static beam angles versus rotational techniques, which has recently re-surfaced due to the advancement of volumetric modulated arc therapy (VMAT). A specific objective is ...
Background: Some ssues in human body are radiobiologically different from water and these inhomogeneity must be considered in dose calcula on in order to achieve an accurate dose delivery. Dose verifica on in complex radia on therapy techniques, such as intensity‐modulated radia on therapy (IMRT) calls for volumetric, ssue equivalent and energy independent dosimeter. The purpose of this study i...
Volumetric modulated arc therapy (VMAT) has found widespread clinical application in recent years. A large number of treatment planning studies have evaluated the potential for VMAT for different disease sites based on the currently available commercial implementations of VMAT planning. In contrast, literature on the underlying mathematical optimization methods used in treatment planning is sca...
