Energy and field size dependence of a silicon diode designed for small-field dosimetry
Purpose: To investigate the energy dependence/spectral sensitivity of silicon diodes designed for small-field dosimetry and obtain response factors (RFs) for arbitrary photon spectra using Monte Carlo (MC) simulations. Methods: The EGSnrc user-code DOSRZnrc was used to calculate the dose deposition in water and in the active volume of a stereotactic diode f...
متن کاملMonte 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...
متن کاملReference dosimetry and small - field dosimetry in external beam radiotherapy : Results from a Danish intercomparison study
max. 2000 char.): A comparison of dosimetry methods at different clinics can be used as a means to uncover systematic uncertainties in radiotherapy. To assess the current status of reference dosimetry and small-field dosimetry in clinical practice, a collaborative comparison study involving several dosimetry methods was performed by DTU Nutech at six Danish clinics. The first part of the interc...
متن کاملValidation of a prototype DiodeAir for small field dosimetry.
Standard commercial diode detectors over-respond within small radiation fields, an effect largely attributable to the relatively high mass-density of silicon. However, Monte Carlo studies can be used to optimise dosimeter designs and have demonstrated that 'mass-density compensation'-for example, introducing a low-density air-gap upstream of a diode's high-density silicon volume-can substantial...
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
