New formula for Calculation of Cobalt-60 Percent Depth Dose
Introduction: On the basis of percent depth dose (PDD) calculation, the application of dosimetry in radiotherapy has an important role to play in reducing the chance of tumor recurrence. The aim of this study is to introduce a new formula for calculating the centeral axis percent depth doses of Cobalt-60 beam. Materials and Methods: In the present study, based on ...

متن کاملMonte Carlo calculation of shielded colpostat effect on rectum received dose in high dose rate brachytherapy with Cobalt-60 sources
Background: In the current study the effect of shielded colpostat on rectum received dose was calculated in cervical brachytherapy using Monte Carlo (MC) method. Materials and Methods: Two 60Co sources of GZP6 brachytherapy unit used for intracavitary treatments were simulated using MCNPX Monte Carlo code. Also the two types of colpostats including shielded and unshielded were simulated inside ...
