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...

Introduction: Cone beam computed tomography (CBCT) is a new method that is able to provide three-dimensional images in radiology and is useful for dentomaxillofacial imaging. This study aimed to investigate the cases administrated CBCT by dentists of Kerman (2015 year). Methods: This cross-sectional study was conducted on dentists in Kerman. The data were gathered using standard research q...

This paper summarizes technological advances in diagnostic radiography, fluoroscopy and computed tomography, mainly the developments in digital detectors and helical CT scanners with multiple-row detectors. It reviews dosimetric concepts and presents the most up-to-date information on the global patterns of use of radiological modalities as well as the trends in diagnostic medical exposure dose...

There is no area of medicine where timely and accurate interpretation of diagnostic imaging studies affects patient management as much as in the Emergency Department. Thirty percent of imaging studies are requested by Emergency Departments, and Emergency Medicine Physicians often interpret their own films. Diagnostic Radiology in Emergency Medicine is explicitly written "to address the mutual v...

abstract   background: the x-ray machines used for radiodiagnosis should meet certain quality assurance (qa) programmes . these are necessary to have good quality radiographs at reasonably low exposure to patients.   materials and methods: dose reduction methods in abdomen x-ray examination were carried out in 10 hospitals in tehran. this paper presents the work, which was implemented on 200 pa...

Cameras embedded in consumer devices have previously been used as physiological information sensors. The waveform of the photoplethysmographic image (PPGi) signals may be significantly affected by the light spectra and intensity. The purpose of this paper is to evaluate the performance of PPGi waveform acquisition in the red, green, and blue channels using a commercial camera in different light...

S ince the discovery of X-rays in 1895, the applications of radiation in medicine have broadened tremendously in scope. Three specialties have emerged during the last 50 years; namely, diagnostic radiology, therapeutic radiology, and nuclear medicine. Nowadays, these specialties are established worldwide in clinical practice with board certification, and in education, training, and research, al...
