A 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 کاملDetermination of the optimal conditions for dental subtraction radiography using a storage phosphor system.
OBJECTIVES To determine the optimal kVp and exposure conditions for digital subtraction radiography system using a storage phosphor system. METHOD Signal-to-noise (SNR) measurements were acquired using a Digora system (Soredex, Helsinki, Finland) of large area, low contrast, clinically realistic details against varying degrees of background attenuation for both single exposure unsubtracted an...
متن کاملComparison of storage phosphor computed radiography with conventional film-screen radiography in the recognition of pneumoconiosis.
Traditional film-screen radiography (FSR) has been useful in the recognition and evaluation of interstitial lung diseases, but is becoming increasingly obsolete. To evaluate the applicability of storage phosphor digital computed radiography (CR) images in the recognition of small lung opacities, we compared image quality and the profusion of small opacities between FSR and CR radiographs. We sc...
متن کاملLiterature review Digital Subtraction Radiography in Dentistry
Introduction Radiography is a main diagnostic tool for detecting dental and maxillofacial lesions 2, . Radiologic images have two dimension of three dimensional reality, hence, the images of different anatomical structures are superimposed on each other and, thus, make it difficult to detect the lesions 2, 4, . Radiographic examination is still left much to be desired as a diagnostic tool: Firs...
متن کاملEffectiveness of the single‐shot dual‐energy subtraction technique for portal images
The aim of the present study was to evaluate the clinical efficacy of the single-shot dual-energy subtraction technique for obtaining portal images. We prepared two storage phosphor plates for this study. A 1 mm thick tungsten sheet was placed between the two storage phosphor plates. A single use of the double-exposure technique provides two portal images simultaneously (i.e., a standard image ...
