Abstract
|
|
|
A mathematical model is presented for the calculation of the depth absorbed dose in water phantom irradiated by high energy Photon beam(10MV X-ray), based on transport theory. The parameters of this model are obtained from the experimental values which were simulated by non-linear regression process method. The calculated absorbed dose distribution is extended to 3-D by using trial function from beam profile field sizes, SSD and depth in water phantom irradiated by high energy Photon beam.
The calculated values using this model are in good agreement with the measured values.
