introduction the main goal of this study was to perform quality control test on all radiography units operating in golestan province of iran. materials and methods forty-four x-ray units were examined based on general accepted programs for quality control. eight parameters including kvp accuracy, kvp reproducibility, ma-time reciprocity, exposure linearity, exposure reproducibility, timer accur...

High Power Lasers produce an intense burst of Bremmstrahlung radiation which has potential applications in broadband x-ray radiography. Since the radiation produced is through the interaction of accelerated electrons with the remaining laser target, these bursts are extremely short – in the region of a few ps. As a result, the laser-produced x-rays are capable of imaging complex dynamic objects...

Background: A study has been conducted to assess two useful radiation protection indices, the annual per-capita effective dose equivalent (AED) and the genetically significant dose (GSD), from conventional diagnostic radiography in 10 counties with more than 1,886,000 inhabitants in Khorasan province in Iran. Materials and Methods: The health centre authorities of Khorasan province were asked t...

introduction: rapid diagnosis of traumatic intrathoracic injuries leads to improvement in patient management. this study was designed to evaluate the diagnostic value of chest radiography (cxr) in comparison to chest computed tomography (ct) scan in diagnosis of traumatic intrathoracic injuries. methods: participants of this prospective diagnostic accuracy study included multiple trauma patient...

Background: Currently, the detection of retained wood is a frequent but challenging task in emergency care. The purpose of this study is to demonstrate improved foreign-body detection with the novel approach of preclinical X-ray dark-field radiography. Methods: At a preclinical dark-field x-ray radiography, setup resolution and sensitivity for simultaneous detection of wooden and metallic parti...

In clinical routine surgeons depend largely on 2D x‐ray radiographs and their experience to plan and evaluate surgical interventions at the knee. Numerous studies have shown that pure 2D x‐ray radiography based measurements are not accurate due to the error in determining accurate radiography magnification and the projection characteristics of 2D radiographs. Using 2D x‐ray radiographs to plan ...

A flexible microdome-grooved Gd(2)O(2)S:Tb scintillator is simulated, fabricated, and characterized for digital radiography applications. According to Monte Carlo simulation results, the dome-grooved structure has a high spatial resolution, which is verified by X-ray image performance of the scintillator. The proposed scintillator has lower X-ray sensitivity than a nonstructured scintillator bu...
