Abstract

Materials and Methods: CT of parotid patients during 2012 to 2014 is used. Twelve patients were evaluated by TPS Core plan, 3D dose distribution and using of dose-volume histogram (DVH), nine techniques were evaluated: a. 6MV photons, 3-fields AP (wedge), PA (wedge), lateral (open), b. unilateral 10 Mev electrons, c. unilateral 14 Mev electrons, d. 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.
