Estimation of Photon Specific Absorbed Fractions in Digimouse Voxel Phantom using Monte Carlo Simulation Code FLUKA
Background: Most preclinical studies are carried out on mice. For internal dose assessment of a mouse, specific absorbed fraction (SAF) values play an important role. In most studies, SAF values are estimated using older standard human organ compositions and values for limited source target pairs.Objective: SAF values for monoenergetic photons of energies 15, 50, 100, 500, 1000 and 4000 keV...
متن کاملConstruction of Voxel-type Phantom Based on Computed Tomographic Data of RANDO Phantom for the Monte Carlo Simulations
The Monte Carlo simulations using the mathematical phantom of a human body model is useful as a method of getting to know the details of the radiation exposure in a human body. However, it is very difficult to evaluate experimentally the validity of the calculation result of the simulation using the human body model. Then, the mathematical phantom of voxel-type (voxel phantom) for the Monte Car...
متن کاملSiemens primus accelerator simulation using EGSnrc Monte Carlo code and gel dosimetry validation with optical computed tomography system by EGSnrc code
Monte Carlo method is the most accurate method for simulation of radiation therapy equipment. The linear accelerators (linac) are currently the most widely used machines in radiation therapy centers. Monte Carlo modeling of the Siemens Primus linear accelerator in 6 MeV beams was used. Square field size of 10 × 10 cm2 produced by the jaws was compared with TLD. Head simulation of Siemens accele...
متن کاملC beam: Monte Carlo simulations and experiment
Charge particle therapy with 12 C ions has the advantage of an enhancement in physical dose distribution due to the Bragg Peak (BP) related to higher Relative Biological Effectiveness (RBE) with respect to X-ray radiotherapy and proton therapy (2.5 for 12 C ions and 1.1 for protons) [1], [2]. The RBE of a 12 C therapeutic beam changes dramatically with depth, especially towards the end of the S...
متن کاملEvaluation of Electron Specific Absorbed Fractions in Organs of Digimouse Voxel Phantom Using Monte Carlo Simulation Code FLUKA
Background: For preclinical evaluations of radiopharmaceuticals, most studies are carried out on mice. Values of electron specific absorbed fractions (SAF) have had vital role in the assessment of absorbed dose. In past studies, electron specific absorbed fractions were given for limited source target pairs using older reports of human organ compositions.Objective: Electron specific absorbed fr...
