ABSTRACT
Objective To design a new method to verify the position of multileaf collimator(MLC)leaf using a two-dimensional ion chamber array(2D-array).Methods 2D-array of PTW T10018 Seven29~(TM) was used to calibrate the accuracy of MLC leaf position of Elekta Precise accelerator.The edge function of the leaf position of MLC was measured and used as the reference value.The precision of MLC leaf was then evaluated through comparing the measured and reference values.Results The accuracy of MLC leaf position was found within?0.1 mm.Conclusion This method of verifying the accuracy of multileaf collimator leaf position is easy,simple and reliable
