Introduction: Due to preventing unnecessary exposure to x-ray, the dentists must acquire adequate information about radiography. Methods: This descriptive cross-sectional study was conducted on general dentists working in Yazd City, selected by convenience sampling method. The data were collected using a three-part questionnaire, the first part included demographic information of the dentists ...
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...
Flash X-ray radiography provides insights into additively manufactured high explosives and the complex wave interactions that can result.
ODC 232.318 (213) Seeds or fruits of 165 forestry species from nine tropical countries were investigated by x-ray radiography. The results showed that the method can be reliably used for detecting empty, filled, insect-attacked, mechanically damaged and diseased seeds or fruits. The applications o f x-ray radiography in tropical forestry for cone, fruit and seed collection, seed processing, nur...
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...
November 1998 2 medicamundi X-ray examinations of the skeleton are, after chest exposures, the most frequently performed type of radiological examination, representing about 30 % of the total. With a few exceptions, projection radiography forms the basis for the diagnosis of skeletal disorders and, in most cases, provides the information for the definitive diagnosis. In traumatology, rheumatolo...
