- W2390789767 abstract "Objective: To study the measurement method of clinical physical data and to verify the accuracy of dose calculation and the precise of beam modeling in three dimension treatment-planning system. Methods: Based on measurement data, such as percentage depth dose (PDD), out factors (Sc, Sp), beam profiles and other data including of X-ray and electron ray, calculation beam model was set out; calculation data and measurement data were verified. By adjusting algorithms parameters to match beam model, we obtain calculation data. Results: The calculated pentage depth dose agreed with the easements within ±1%(of the dose maximum along the beam axis), and the beam profiles agreed with the measurements within ±3%(or ± 2mm in the penumbra region and high dose gradient region). Conclusions: To obtain better and effective treatment planning system, the precise measurement data and accurate algorithms model must be set out completely. Those enable us to provide more detailed beam characteristics for beam fields than a measurement method, and which can provide better quality assure and quality control." @default.
