A simple mathematical model to calculate dose distribution of the Co-60 beam

Abstract EN

The measurement of dose distribution for any radiotherapeatic device is essential for good treatment planning.

Therefore, dose distribution were measured for the field size [F.S = (10 x 10)cm²], then we use mathematical equation according to Fermi-Dirac distribution law after modified it, in this equation two parameter (k) and (n) are directly related to the field size (a), and the depth (d).

So we can contract a theoretical curve by calculating (k), (n) and putting them in to this equation.
