Mixed beam technique using 6MV photon and 10 Mev electron (1:4 weighting), e. Mixed beam technique using 6MV photon and 14 Mev electron (1:4 weighting), f. unilateral 10 Mev electrons with bolus (0.5 cm bolus is used), g. unilateral 14 Mev electrons with bolus (0.5 cm bolus is used), h. Mixed beam technique using 6MV photon and 10 Mev electron (1:4 weighting) with Bolus (0.5 cm bolus is used), i. Mixed beam technique using 6MV photon and 14Mev electron (1:4 weighting) with Bolus (0.5 cm bolus is used) Results: Using of DVH to appraise, the dose to OARs are 0 for techniques 6MV photons, (3-fields), unilateral 10 Mev electrons with and without Bolus, unilateral 14 Mev electrons with & without Bolus. The highest conformal and homogeneity index and near to 1 were for 6MV photons, 3-fields, unilateral 14 Mev electrons with and without Bolus, mixed beam technique using 6MV photon and 14 Mev electron with and without Bolus.
