Tolerance levels of CT number to electron density table for photon beam in radiotherapy treatment planning system
The accuracy of computed tomography number to electron density (CT-ED) calibration is a key component for dose calculations in an inhomogeneous medium. In a previous work, it was shown that the tolerance levels of CT-ED calibration became stricter with an increase in tissue thickness and decrease in the effective energy of a photon beam. For the last decade, a low effective energy photon beam (...

15 صفحه اولStandard calibration of ionization chambers used in radiation therapy dosimetry and evaluation of uncertainties
Background: Absolute dosimetry of external beam radiotherapy is carried out by the use of ionization chambers. These chambers must be calibrated at a standard dosimetry laboratory before any use in clinical dosimetry. The secondary standard dosimetry laboratory of Iran (SSDL) has the duty of calibrating the ionization chambers used in radiotherapy centers in Iran. Materials and Methods...
متن کاملMonte Carlo calculation of shielding properties of newly developed heavy concretes for megavoltage photon beam spectra used in radiation therapy
Introduction: Globally, the need for radiotherapy as a part of cancer management increases every year. Thus, the shielding for megavoltage radiotherapy rooms is of great importance. Materials and Methods: In the present study, 14 types of developed high-density concrete with densities ranging from 2.45 to 5.11 were simulated by using Monte Carlo method. The linear attenuation coefficient and t...
متن کاملPhoton-number-squeezed recombination radiation in semiconductors
We recently reported the generation of cw photon-numbersqueezed (sub-Poisson) light from a Franck-Hertz experiment in which Hg vapor was excited by inelastic collisions with a space-charge-limited (quiet) electron beam.' The experiment operates by transferring the anticlustering properties of the electrons, resulting from Coulomb repulsion, to the photons. The direction of transfer is the inver...
