Dose distribution in thorax using measured and calculation algorithm method

ABSTRACT

In This study a trial has been done to verify the treatment planning algorithm implemented on the theraplan TP-11 system. To achieve this goal the thorax part of a humanoid [Rando] Phantom is used. The thorax part is irradiated using 10 Mev electron beam from varian accelerator and the dose distribution is monitored by Lif [700] TLD. The experimental results are compared with the results of the algorithm of the theraplan TP-11 System. The study revealed that the results due to the algorithm at the penumbral region of the radiation field, [area under rib and area between ribs] can vary and read as much as 23%. A discussion of the results is also presented
