Authors
abstract
background: the purpose of this study was to investigate the application of the monte carlo technique to calculate and analysis of dosimetric parameters for electron beams used in radiotherapy. this technique is based on statistical method and has a powerful role in different radiotherapy aspects. materials and methods: the simulated medical linear accelerator was the varian clinac 2100c. the electron beams 9, 12 and 20 mev were simulated by mcnp4c monte carlo code. the beam geometry was 10 ã— 10 cm 2 applicator, 100 cm ssd on the surface of homogenous water phantom. central-axis percentage depth dose (pdd) curves and dose profile (off axis ratio) were obtained to compare with experimental measurements. â results: the comparisons between calculated and experimental results show good agreement (within â±3%). conclusions: the mcnp4c code is a powerful tool for acquiring electron dosimetry results as well as other applications in radiotherapy.

Monte carlo simulation of varian clinac iX 10 MV photon beam for small field dosimetry
Background: The lack of lateral electronic disequilibrium (LED) becomes a main problem in small field. This factor affects the dose in target volume cannot predict correctly. In addition, utilization of high-energy linear accelerator (10 MV) can emit some unwanted particles (electron contamination). Therefore, the aim of this study was to characterize head linear accelerator (linac) Varian Clin...

We have simulated the head geometry of a Varian Clinac 2100C/2300C medical accelerator in a Monte Carlo calculation to produce photoneutrons and transport them through the head shielding into a typical therapy room (modeled by a test cell at Varian Associates). The fast neutron leakage fluence and energy spectra have been calculated at 7 positions around the linac head for typical beam operatio...
