Quality comparison of direct digital panoramic radiography and computed radiography panoramic
BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...
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 کاملA flat-panel detector digital radiography and a storage phosphor computed radiography: screening for pneumoconioses.
Storage phosphor computed radiography (SR) and flat-panel detector (FPD) radiography are two types of digital X-ray utilizing different techniques. We compared these two techniques with conventional analogue chest radiograph (AR) among pneumoconiotic patients and healthy controls. Thirty individuals consisting of 20 silica-exposed ex-workers and 10 healthy controls without occupational exposure...
متن کاملGoing Digital: Assessing the Viability of Computed Radiography
including the Navy’s Fleet Readiness Centers (FRC) are faced with replacing aging chemical and film-based radiographic imaging systems used for non-destructive testing (NDT) (or nondestructive inspection (NDI)) with systems that do not rely on such an approach—so called computed radiography (CR) systems. However there are benefits, requirements, concerns, and challenges associated with implemen...
متن کاملOptimization of Dose and Image Quality in Full-fiand Computed Radiography Systems for Common Digital Radiographic Examinations
IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...
