چکیده
Stereotactic radiosurgery (SRS) using external beams of radiation has become an important method of treatment of small intracranial lesions such as arteriovenous malformations, benign or malignant primary tumours and isolated metastases. In this technique, a high dose of radiation is delivered to the stereotactically localized lesion, the adjacent normal brain tissue being minimaly irradiated.

متن کاملInvestigations of parameters affecting the photon energy spectra of an 18 MV Varian 2100C/D linear accelerator
Radiotherapy using linear accelerators is known as an effective modality for cancer treatment. The photons energy of treatment beams significantly affect the dose distribution. Therefore, it is important to accurately evaluate the photon energy spectra. In this study, MCNPX Monte Carlo code (version 2.6.0) was used to simulate an 18 MV photon beam of a Varian 2100C/D linear accelerator. By matc...
متن کاملA Monte Carlo Simulation of Photon Beam Generated by a Linear Accelerator
ntroduction: Monte Carlo simulation is the most accurate method of simulating radiation transport and predicting doses at different points of interest in radiotherapy. A great advantage of the Monte Carlo method compared to the deterministic methods is the ability to deal accurately with any complex geometry. Its disadvantage is the extremely long computing time r...
متن کاملA full quantitative analysis of 18 MV photon beam from 2100 C/D-Varian clinical linear accelerator with and without flattening filter
Background: During intensity modulated radiation therapy (IMRT) technique, theoretically, presence of flattening filter (FF) across the beamline of clinical linear accelerator (linac) is not essential to obtain uniform lateral profiles due to intensity modulation of photon beams by multileaf collimators (MLCs). The aim of this study was to investigate the dosimetrical properties of 18 MV photon...
