Introduction: Extensive use of diagnostic radiology is the largest contributor to total population radiation doses. Thus, appropriate equipment and safe practice are necessary for good-quality images with optimal doses. This study aimed to perform quality control (QC) audit for radiography and fluoroscopy devices owned by private sector in Syria (2005-2013) to verify compliance of performance o...

Pressure induced densification and compression of a reprocessed sample of borosilicate glass has been studied by X-ray radiography and energy dispersive X-ray diffraction using a Paris-Edinburgh (PE) press at a synchrotron X-ray source. The reprocessing of a commercial borosilicate glass was carried out by cyclical melting and cooling. Gold foil pressure markers were used to obtain the sample p...

Flat-panel X-ray image detectors have been shown to be suitable to replace the conventional X-ray filmjscreen cassettes for medical radiography (static or snapshot imaging). They are capable of capturing the X-ray image digitally immediately after the X-ray exposure which permits a convenient clinical transition to digital radiography. There are two general approaches to the flat-panel X-ray de...

Discovered by Wilhelm Roentgen in 1895, X-ray technology is the oldest and most commonly used form of medical imaging and remains an important tool for the diagnosis of many disorders. X-rays are generated when a beam of electrons is accelerated by high voltage and hits a metal probe. The kinetic energy released is transformed into quanta of emitted X-ray radiation. X-rays are absorbed by the m...

Endobronchial tuberculosis and chest radiography I read, with interest, the article entitled “Clinical and Para-clinical Presentations of Endobronchial Tuberculosis” by Ahmadi Hoseini H. S. et al. (1) published in this journal. I would like to focus on some details about the chest X-ray of patients as elaborated by the authors in the results section. Accordingly, the findings of chest radiograp...

A method for quantitative measurements of gas and liquid distributions is demonstrated using simultaneous x-ray fluorescence and radiography of both phases in an atomizing coaxial spray. Synchrotron radiation at 10.1 keV from the Advanced Photon Source at Argonne National Laboratory is used for x-ray fluorescence of argon gas and two tracer elements seeded into the liquid stream. Simultaneous t...

We have developed a combinatorial method for determining optimum tissue scaffold composition for several X-ray imaging techniques. X-ray radiography and X-ray microcomputed tomography enable non-invasive imaging of implants in vivo and in vitro. However, highly porous polymeric scaffolds do not always possess sufficient X-ray contrast and are therefore difficult to image with X-ray-based techni...

Digital radiography offers the potential of improved image quality as well as providing opportunities for advances in medical image management, computer-aided diagnosis and teleradiology. Image quality is intimately linked to the precise and accurate acquisition of information from the x-ray beam transmitted by the patient, i.e. to the performance of the x-ray detector. Detectors for digital ra...
