RESUMO
The standardization of data transfer plays an important role in precise radiotherapy,not only boosting the speed but also ensuring the treatment quality.In this article,a method for beam data generation and transfer is introduced based on DICOM RT Standard.Firstly,the realization procedure of this module is presented.Secondly,the realization means of two different IMRT methods including SMLC and DMLC are explained respectively.Finally,the system's validity is proved with instances.
RESUMO
Precise verification is required in the execution of intensity-modulated radiotherapy (IMRT) for its complexity. Thereinto, the verification of dose distributions is the emphases and nodus. Some problems in the verification by using radiotherapy planning dose verification system (DVS) are explored such as how to verify the precision and credibility, how to reduce errors in every verification step, how to provide quantified analysis. A suit of practical methods and techniques are summarized from equipment selection to quantified analysis.
