Using Varian Photon Beam Source Model for Dose Calculation of Small Fields

چکیده
The use of small fi elds in radiotherapy techniques has increased substantially, in particular in stereotactic treatments and large uniform or nonuniform fi elds that are composed of small fi elds, such as for intensity-modulated radiation therapy (IMRT). This clinical perspective will focus on an experimental evaluation of the dose calculation accuracy of the anisotropic analytical algorithm (AAA) and Acuros® XB advanced dose calculation (Acuros XB) for small fi eld sizes. All measurements were performed with fi lm, as well as with point dose detectors suitable for small fi eld aperture. Clinical perspectives | Varian Photon Beam Source Model

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...

Background: Small photon fields are increasingly used in modern radiotherapy especially in intensity modulated radiation therapy (IMRT) and stereotactic radiosurgery (SRS) treatments. Accurate beam profile and central axis depth doses measurements of such beams are complicated due to the electron disequilibrium. Hence the EBT2 (external beam therapy) Gafchromic film was used for dosimetry of sm...
