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 کاملThyroids Dose Evaluation and Calculation of Backscatter Factors for Co-60 Irradiations
The aim of the study is evaluation of absorbed doses for thyroids by using neck phantoms. For this purpose, it was arranged the irradiation set with different phantoms. Three different materials were used for phantom materials as, water, paraffin and wood. The phantoms were three different dimensions for simulation of different ages and human race for each material. Co-60 gamma source was used ...
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 ...
متن کاملDose measurement of cobalt-60 radiotherapy beams in treatment fields.
BACKGROUND Radiation-therapy is a complex process with multiple steps, each of which has an impact on the quality of treatment. Accurate dosimetry is a critical step during the radiotherapy of cancer patients.The aim of the present study was to measure and evaluate the doses of two cobalt- 60 (60Co) teletherapy units GWXJ80 of NPIC China and Theratron 780 of AECL Canada at various points within...
