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 کاملPractical guidelines for radiographers to improve computed radiography image quality
Computed Radiography (CR) has become a major digital imaging modality in a modern radiological department. CR system changes workflow from the conventional way of using film/screen by employing photostimulable phosphor plate technology. This results in the changing perspectives of technical, artefacts and quality control issues in radiology departments. Guidelines for better image quality in di...
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 کاملReduction in retake rates and radiation dosage through computed radiography.
The availability of computed radiography has opened the possibility of using reduced dosage for radiographs in clinical settings and reducing the retake rate. A prospective controlled study was carried out over a period of four months comparing conventional X-rays and computed radiography. The aim was to assess if computed radiography at 50% normal dosage would result in films of adequate quali...
متن کاملNeonatal chest computed radiography: image processing and optimal image display.
OBJECTIVE The purpose of this study was to determine soft-copy image display preferences of brightness, latitude, and detail contrast for neonatal chest computed radiography to establish a baseline for future work on low-dose imaging. CONCLUSION Observers preferred brighter images with higher detail contrast and narrow to middle latitude for soft-copy display compared with the typical screen-...
