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...
متن کاملOrgan and effective dose arising from conventional diagnostic X-ray examinations by Monte Carlo simulation (MCNP-4C Code)
ABSTRACTBackground: Monte Carlo simulation has been used by many researchers to calculate organ and effective dose of patients arising from conventional X-ray examinations. In this study the radiation transport code, MCNP-4C, has been used to perform Monte Carlo simulations to estimate radiation dose delivered to different organs in conventional X-ray examinations.Material and Methods: In this...
متن کاملEvaluation of PERSH Criteria to Avoid Unnecessary Chest X-ray in Patients with Blunt Chest Trauma: A Qualitative Study
Background: Chest X-rays (CXRs) are traditionally performed to determine intra-thoracic injuries in all blunt chest trauma patients in Shahid Bahonar hospital in Kerman. As there are some disadvantages upon CXR and radiation exposure, therefore, this study aimed to evaluate the role of CXR in the diagnosis of intra-thoracic injuries caused by any blunt chest trauma. Me...
متن کاملMonte 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...
متن کاملAssessment of X-Ray Crosstalk in a Computed Tomography Scanner with Small Detector Elements Using Monte Carlo Method
Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...
