Computed Radiography dose optimization in pediatric patients
Radiation dose reduction in pediatric X-ray imaging is especially important because of children radiation sensitivity. For any radiographic examination performed at a fixed radiographic tube potential, the patient absorbed dose is directly proportional to the value of milliampere-seconds (mAs) selected by the operator. Nevertheless, reducing X-ray exposure has the unavoidable disadvantage of in...
متن کاملEntrance skin dose assessment of selected computed radiography facilities in Ghana
Background: The basic challenge with computed radiography (CR) systems is the large dynamic range which provides an opportunity for radiographers to gradually increase exposure factors and still produce good image quality, a practice that can lead to dose creep. Materials and Methods: The aim of this study was to establish the entrance skin dose (ESD) values for nine selected examinations in t...
متن کاملOptimizing the Exposure Indicator as a Dose Management Strategy in Computed Radiography.
PURPOSE To investigate a technique for optimizing radiation dose and image quality for a computed radiography system. METHODS Entrance skin doses were measured for phantom models of the pelvis and lumbar spine imaged using the vendor's recommended exposure settings (ie, the reference doses) as well as doses above and below the vendor's recommended settings for both body parts. Images were ass...
متن کاملBreakthroughs in Radiography: Computed Radiography
CE Email comments/questions to [email protected], fax 800-556-3288, or log on to www.VetLearn.com Computed radiography (CR) is a digital imaging technology and digital x-ray image management system that has been used in human and veterinary medicine since the 1980s. CR helps eliminate many of the disadvantages of traditional radiography. A storage phosphor plate collects the pattern of x...
متن کاملEvaluation of Gonadal Exposure Dose in Long Bone Plain Radiography for Radiation Protection
Introduction: Long bone examination in standing position, as one of the diagnostic methods in plain radiography, is most commonly used in the field of medical diagnosis, especially leg length discrepancy. However, with regard to this examination, reproductive organs are exposed to radiation as they are placed in the adjacent area to the long bone. Due to the sensitivit...
