Organ and effective dose arising from conventional diagnostic X-ray examinations by Monte Carlo simulation (MCNP-4C Code)

Unfolding X-ray spectrum in the diagnostic range using the Monte Carlo Code MCNP5

Introduction: Unfolding X-ray spectrum is a powerful tool for quality control of X-ray tubes. Generally, the acquisition of the X-ray spectrum in diagnostic radiology departments is complicated and difficult due to high photon flux. Measurement of x ray spectra using radiation detectors could not be performed accurately, because of the pulse pile up. Therefore, indirect methods...

Monte Carlo Modeling of an X-ray Fluorescence Detection System by the Mcnp Code

Evaluation of Organ and Effective Doses to Patients Arising From Some Common X-Ray Examinations by PCXMC Program in Sabzevar, Iran

Introduction The purpose of this study was to estimate organ and effective doses in patients undergoing some common X-ray examinations in Sabzevar, Iran. The effective dose is one of the best parameters for describing the amount of radiation dose received by a patient undergoing any diagnostic X-ray examination. The public dose from X-ray examinations depends on various factors, and its contrib...

Evaluation of Organ Specific peripheral dose for Gamma knife 4C based on Monte Carlo

Introduction: Stereotactic Gamma Knife radiosurgery has been widely used for treating brain tumors. The scattered radiation outside of treatment field (peripheral dose) can induce the secondary cancer to specific organ. This paper investigated the absorbed dose to eyes, thyroid, heart, lung, breast and colon using a Monte Carlo technique for Mird phantom. We also study the ef...

Evaluation of X-ray absorbed dose in thyroid during CXR imaging of the chest by Monte Carlo simulation (DOSXYZnrc)

Abstract:   Introduction: Chest radiography is one of the most common X-ray imaging procedures performed worldwide. During this process, in addition to the chest, other tissues, including the thyroid, are also exposed to radiation. Due to the fact that one of the most important risk factors for thyroid cancer is ionizing radiation, measuring the absorption of X- rays in the thyroid is of spec...

Monte Carlo Method for Radiological X-ray Examinations

The organ doses and the effective dose of patients exposed at an X-ray beam, having photon energies between 10–150 keV, are analyzed by using a new method named IradMed. Three major radiological procedures, mammography, radiography and Computer Tomography are considered. The Rayleigh scattering, the Compton scattering and the photoelectric effect were taken into account for patient dose calcula...
