Radiotherapy is a treatment technique by delivering radiation using considerable energy. We need a plan to make sure the dose administered in accordance with the needs of patients. One of the planning that must be done is by performing dose calculations. This final project aims to carry out calculations of dose distributions in homogeneous media using the Pencil Beam Convolution techniques. In this study, we created a simulation model using a large energy radiation source 8mV and field-size 5x5cm2 and 20x20cm2. This simulation was performed by varying the amount of Beamlet. The results of the simulation were compared with experimental results that have been carried out at the University Hospital, Uppsala, Sweden (Ahnesjo, 1992). <br /> <br /> <br /> We have analyzed the dose distributions that have been obtained using the Percentage Depth Dose (PDD), through the analysis of depth at the maximum dose (Z-max) and also the falling region. We obtained the different value of Z-max (Table 2 and 3), but we got the similar characteristics of the falling regions (Graph 16 and 18).
