摘要:The advent of modern technologies and mega voltage beam energies in radiation therapy has increased the demand of higher degree of accuracy and efficiency.We intended to increase the efficiency of the radiation therapy by applying mathematical and computational tools not only to verify the measured Percentage Depth Dose(PDD)data but also to aid in rapid machine commissioning.Lagrange’s interpolation method was used to calculate the absorbed doses at depths with step size of 1cm.The measured PDD data at selected depths with 5 to 8 cm separation have been used as the points of interpolations.The interpolated results precisely agree with the measured data,and can be used as the input data for treatment planning.This exploration should be extended for the interpolation of dose for different field sizes as well so that the commissioning time can be further decreased and the reliability of the measured data is assured.
